I know the VXR came with adaptive cruise control, I just wonder if anyone would know if it can be installed in the LT models? All models have the sensors for collision alert but I wasn't sure if it was just something that could be reprogrammed or whether a new module was needed?
Can the likes of this module be retrofitted?
Is all the wiring there?
Does it/can it be made to "talk" via the CANBUS to the cruise control system?
Once the module has been fitted, is it just a matter of using something like a diagnostic tool to enable the module and get Actuve Cruise Control working?
I kind of suspect it's not quite that simple as that. I think the VIN or build number determines what features were fitted at the factory and it may not be easy to over ride those factory settings.

The wiring will be missing and i am sure there will be some other module that is needed or programming required because the system uses both the radar and forward looking camera as data inputs for adaptive cruise control.
Don't we have the forward looking camera for Lane Keep Assist and other functions? I kind of suspect the wiring may be there. Just from a manufacturing point of view and based on experience with other cars. One wiring loom is cheaper to make than customising the loom for the different features.
However just because the wiring and other bitd may may be there I not suggesting it's possble to retrofit the ACC.

In some cases the one loom is made and others a loom will have the same main connector plugs but it will be missing the extra wires.
It depends on the loom location and whether it is a slave loom plugged into a master loom.
For instance the vf front bumper, some have drls some have fogs and drls and others have none.
The bumper has a slave loom routed through it and it does not contain the wires for the features the bumper does not have, the master loom does have the wires.
The lt and rs have different dash looms to the rsv, vxr calais-v around the infotainment and the steering wheel.
the wires are not the main problem though because even if they are missing you could run them separately.
the main problem is the module that does the computing for the adaptive cruse, it uses the radar, camera and multiple other sensors as data inputs to calculate the actions for controlling the speed and braking and that will be some form of program which wont be in the non adaptive cruise vehicles.
it would require some sort of firmware flash and more modules.
the steering wheel control for cruise is different in the vxr compared to the lt/rs so you would need to get that and the clock spring to match because the wires are different in the wheel and then you would need to set the bcm to expect different/new serial data(canbus) messages because they are different.
the instrument cluster might also need to be changed.
the more complex vehicles get the harder it becomes to retrofit things
even the instrument cluster is a problem, trying to retrofit the full color cluster seems to be a no go because of the different steering wheels and serial data messages, the controls for the cluster are different on the wheel so while you can put the cluster in you cannot control it unless you change the wheel controls which raise issues controlling the infotainment system.
i dont know if it is possible to add adaptive cruise to the lower spec but i would say it would be incredibly hard and unless they are working on it in europe or the usa i dont think a solution would be found because the insignia is really not that popular enough here for people to put the r&d into something like that.
a bit of info from the manual
ADAPTIVE CRUISE CONTROL DESCRIPTION AND OPERATION
The adaptive cruise control system is an enhanced cruise control system with the ability to sense and
react to forward traffic. Compared to the common cruise control system found on many vehicles, the
main functional enhancement of the adaptive cruise control system is the ability to detect the presence of
a vehicle in the path of the adaptive cruise control vehicle. Adaptive cruise control retains the existing
cruise control feature that controls the vehicle speed to the driver selected speed. However, adaptive
cruise control allows a driver to set and maintain a following distance to the preceding nearest vehicle in
the path ahead. The active safety control module controller calculates a follow speed limit to ensure an
acceptable distance is maintained to the preceding vehicle in front, should one be present. The adaptive
cruise control system automatically adjusts the speed when the vehicle comes up behind a slower
travelling vehicle in front. The system applies limited automatic braking and throttle control without
driver input when necessary to maintain the set following distance. The preceding vehicle's speed and
acceleration along with the active cruise control vehicle speed and acceleration and the distance between
the two vehicles are factors used by the active safety control module controller to determine the follow
speed limit. The vehicle speeds up to the original driver selected set speed when the pathway becomes
clear without driver input.
The adaptive cruise control functionality depends on various modules on the vehicle to function and
each module performs a function that is critical to the proper operation of the adaptive cruise control
system. Adaptive cruise control will not operate if any components fail. Communication between
modules is via serial data. The following is a functional description of the active safety control module
and the other associated components: Active Safety Control Module
Body Control Module
Digital Map Module
Engine Control Module
Electronic Brake Control Module
Transmission Control Module
Instrument Cluster
Cruise Control Switch
Gap Switch
Active Safety Control Module
The active safety control module analyzes data from various modules, sensors, and switches to provide
enhanced safety features. In addition to enhanced safety features, the active safety control module
provides the adaptive cruise control system functionality. The active safety control module analyzes data
from the long range radar sensor module, front short range radar sensor modules, and frontview camera
module to identify and classify objects in the road environment. The system scans the road environment
to detect targets within its specified field of view. The active safety control module then sends throttle
and/or brake commands to the engine control module (ECM) and electronic brake control module
(EBCM) via serial data in order to control the vehicle acceleration/deceleration based on the data from
the modules. The ECM and EBCM provide throttle control and automatic braking needed for proper
cruise speed adjustment. The following is a list of the active safety control module functions pertaining
to the adaptive cruise control functionality:
/
The active safety control module processes the road environment to get data concerning any
vehicle ahead of the adaptive cruise control vehicle. Detection, parameter estimation, tracking,
object classification and diagnostics are the primary functions. When an object is detected, the
controller calculates the object range, range rate, acceleration and azimuth angle parameters.
The active safety control module performs adaptive cruise control state processing automatically -
distance control or speed control. The adaptive cruise control operates in 2 possible states - cruise
or follow. The normal operating state is cruise, whereby the vehicle speed is controlled to match
the driver selected set speed. When a preceding forward target is identified, the adaptive cruise
control system will automatically transition into the follow speed state to provide proper lane
spacing behind the target vehicle in front. The preceding vehicle's speed and acceleration, with the
adaptive cruise control vehicle speed, acceleration and distance between the two vehicles will be
used to determine the adaptive cruise control follow speed limit. The adaptive cruise control
follow speed limit will ensure that an acceptable distance is maintained to the preceding vehicle.
The active safety control module determines the follow speed limit for throttle control by the
ECM.
The active safety control module arbitrates the adaptive cruise control system brake and throttle
control between the EBCM and the ECM.
The active safety control module requests brake light activation during automatic braking.
The active safety control module provides operational feedback to the vehicle driver. The active
safety control module sends signals for telltales and messages to be displayed on the instrument
cluster or driver information center. Body Control Module
The following are the adaptive cruise control System functions provided by the body control module
(BCM):
The BCM provides a translating gateway for the high speed GMLAN serial data circuit.
The BCM reads all cruise control switches and the gap switch. The active safety control module
monitors a variety of user operated switches from the BCM switch status information sent via the
GMLAN serial data circuit.
The BCM illuminates the brake light based on a GMLAN message from the active safety control
module during automatic braking.
The BCM measures the brake pedal position and sends brake pedal travel status via GMLAN
serial data circuit to the ECM. The ECM disengages the adaptive cruise control system when the
brake is applied by the driver pressing the brake pedal.
The BCM serves as a gateway to the instrument cluster and driver information center. The BCM
will generate visual warnings based on high speed GMLAN serial data messages from the active
safety control module. Digital Map Module
The following are the adaptive cruise control System functions provided by the Digital Map Module:
The Digital Map Module (DMM) is capable of determining vehicle position and localization and
then communicating navigational and predictive data
The Digital Map Module provides information to the Cruise system that the vehicle is on an
acceptable freeway or highway for engaging the feature
The Digital Map Module provides road information to the Cruise system about road
characteristics, like exits and merge areas that will alert the system to changing road conditions Engine Control Module
The following are the adaptive cruise control system functions performed by the engine control module
(ECM):
The ECM provides the electronic throttle control to the adaptive cruise control System. The ECM
is also responsible for determining when a driver is overriding the adaptive cruise control throttle
position by pressing the accelerator pedal.
/
The ECM processes the cruise control switch requests received via the GMLAN serial data circuit
from the BCM. Engaging and disengaging the adaptive cruise control system are functions
performed by the ECM.
The ECM determines the driver selected vehicle speed. Unless the adaptive cruise control module
requests a lower vehicle speed, the ECM will control the vehicle speed to the driver selected set
speed.
The ECM allows automatic braking without disengaging the adaptive cruise control. Electronic Brake Control Module
The following are the adaptive cruise control System functions performed by the electronic brake
control module (EBCM):
The EBCM controls the operation of the Antilock Brake System.
The EBCM provides automatic braking for the adaptive cruise control system. The active safety
control module will request vehicle deceleration via high speed GMLAN serial data circuit.
The EBCM determines when the driver - applied brake pressure is active. The EBCM will
communicate this status via the GMLAN serial data circuit to the BCM.
The EBCM releases vehicle automatic braking when there is a throttle override by the driver
pressing the accelerator.
The EBCM predicts brake temperatures. Due to automatic braking, the brake system may
overheat. When the brakes are overheated, the EBCM requests the adaptive cruise control System
to be temporarily shut down by the ECM until the brakes cool to a normal operating temperature. Transmission Control Module
The transmission control module (TCM) provides a down shift to protect the brakes. When the TCM
detects some driver braking activity or adaptive cruise control automatic braking activity, the TCM
down shifts the vehicle transmission to increase engine braking. This helps reduce braking activity,
extend brake pad life and reduce brake system overheating. Instrument Cluster
The driver information center is a part of the instrument cluster and displays the adaptive cruise control
system warning messages. The active safety control module requests messages to be displayed on the
driver information center by sending a GMLAN request to the BCM. The BCM sends a GMLAN serial
data request to the instrument cluster demanding the display of the warning message. When the message
is acknowledged by the driver and the cause of the message resolved, the driver information center turns
the message off. The adaptive cruise control system will not operate if the driver information center
fails. Cruise Control Switch
The cruise control switch, functionally is a common feature that is shared between the adaptive cruise
control system and the regular cruise control system. The adaptive cruise control system will not operate
if any cruise switch fails. The cruise control switch comprises the following cruise control function
switches:
On/Off switch
Set/decrease switch
Resume/increase switch
The cruise control function switches are arranged in a resistive ladder design whereby each switch
function is set up with different resistance values. The BCM through the cruise control switch signal
circuit detects a predetermined voltage value when any cruise control switch function is activated. The
associated cruise control function signal detected by the BCM is then sent to the engine control module
(ECM) as a GMLAN serial data circuit message. The ECM on receiving the message provides the cruise
control function requested by the BCM. The ECM is responsible for recognizing and responding to
cruise control switch requests sent by the BCM. The cruise control function switches are used by the
ECM to communicate to the active safety control module the driver selected vehicle speed. The driver
selected vehicle speed is communicated through GMLAN serial data circuit to the active safety control
/
module and the BCM. The adaptive cruise control system engages and adjusts vehicle speeds based on
the activation of the following cruise control function switches:
Cruise Control On/Off Switch
The BCM monitors the switch signal circuit in order to determine when the On/Off switch is disabled or
activated. The BCM detects a predetermined voltage value on the switch signal circuit. The On/Off
switch state is then relayed to the ECM via the GMLAN serial data circuit. The ECM sends the On/Off
switch input status to the active safety control module. When the On/Off switch is turned ON, the
adaptive cruise control system enters either a standby enabled or a standby disabled mode. The standby
enabled mode indicates that every condition required for the adaptive cruise control system to function
has been met, but the adaptive cruise control is not engaged. When the adaptive cruise control is in the
standby disabled mode, the conditions necessary for the adaptive cruise control system to function has
not been met. When the On/Off switch is turned OFF, the adaptive cruise control will enter the disabled
mode. The adaptive cruise control will not activate in the disabled mode. Cruise Control Set/Decrease Switch
The adaptive cruise control system is engaged when the adaptive cruise control On/Off switch is turned
ON and the set/decrease switch is momentarily pressed and released. When the set/decrease switch is
pressed, the selected vehicle speed is set to the current vehicle speed by the ECM. The vehicle speed
must be at or greater than 40 km/h (25 MPH). The selected vehicle speed is displayed by the driver
information center. While in the engaged state, the selected vehicle speed and the following distance can
be adjusted. Pressing and holding the set/decrease switch, when the adaptive cruise control system is
engaged, will decrease the selected vehicle speed without deactivating the adaptive cruise control.
Momentarily pressing and releasing the set/decrease switch, when the adaptive cruise control is
engaged, decreased the selected vehicle speed by 1.6 km/h (1 MPH) for each time that the set/decrease
switch is pressed. Cruise Control Resume/Increase Switch
The resume/increase switch is used in order to increase the selected vehicle speed when adaptive cruise
control is active. The amount selected vehicle speed can be increased from the resume/increase switch
depends on how long the switch is pressed. The presence of a slower moving vehicle in the path of the
adaptive cruise control vehicle will limit the extent to which the selected vehicle speed can be achieved.
If there is no preceding vehicle in front, limiting the adaptive cruise control vehicle acceleration, then
the vehicle speed that is attained is the new selected vehicle speed. The current selected vehicle speed is
displayed by the driver information center. Acceleration is terminated when the resume/increase switch
is released. Momentarily pressing and releasing the resume/increase switch will allow the selected
vehicle to accelerate in at 1.6 km/h (1 MPH) increments for each time that the resume/increase switch is
momentarily pressed. Gap Switch
The gap switch allows the driver to determine how closely the adaptive cruise control vehicle follows a
target vehicle while adaptive cruise control is engaged. When the adaptive cruise control vehicle speed
is being limited due to a slower travelling vehicle, the adaptive cruise control vehicle speed is
automatically controlled to the follow speed limit. The gap switch has 3 following distance selections
that range from 1 - 2 s. The gap switch following distance between the adaptive cruise control vehicle
and the target vehicle is expressed in time as opposed to actual distance. The distance maintained for a
selected gap will vary based on vehicle speed. The faster the vehicle speed, the further back you will
follow. The gap setting can only be adjusted when the adaptive cruise control system is engaged. The
gap switch is hard-wired to the BCM. Based on voltage variations, the BCM is able to read the gap
switch selection and communicates the switch status on the GMLAN serial data circuit to the active
safety control module. The gap switch is a momentary switch.
The initial push of the gap switch recalls the current setting and activates the display. Subsequent pushes
of the gap switch will change the gap setting. Driver Information Messages
Adaptive Cruise Control Temporarily Unavailable
/
The active safety control module will send this message if the adaptive cruise control has been
disengage or disabled. There are many reasons that can cause this, some will also set DTCs. Check
vehicle for DTCs and also check the adaptive cruise control enable and disengage scan tool data.
Definitions of parameters can be found in active safety control module scan tool information.
Service Driver Assist System
This message can be set by either the active safety control module if there is a problem with the driver
assist system or by the memory seat module if there is a problem with the haptic seat circuits. Check
vehicle for DTCs.
Service Adaptive Cruise Control and Service Front Camera
The message is set if the active safety control module is not communicating to the instrument cluster.
Check vehicle for DTCs.
Set Speed
The adaptive cruise control vehicle set speed is displayed at all times in the driver information center
when adaptive cruise control is engaged. The active safety control module set speed display request is
sent to the instrument cluster via the GMLAN serial data circuit. Follow Distance
The driver information center displays the driver selected following distance when adaptive cruise
control is engaged and the gap switch is active. The current follow distance setting is displayed in the
driver information center for a few seconds after the gap switch is pressed to increase or decrease the
following distance. The active safety control module follow distance display request is sent to the
instrument cluster via the GMLAN serial data circuit. Vehicle Ahead Indicator
The vehicle ahead indicator is displayed in the instrument cluster hen the radar identifies an in-path
vehicle. The vehicle ahead indicator is a warning to the driver that a vehicle is ahead. The indicator also
serves as a feedback to the driver that the radar is functioning properly. The active safety control module
commands the display of the vehicle ahead indicator via a GMLAN serial data message to the
instrument cluster. The vehicle ahead indicator only displays with the adaptive cruise control active and
may sometimes display for stationary road objects
I just got my MY19 Calais ZB Tourer and was wondering. Does it have Adaptive cruise control? With the cruise control on I was coming too close to the cars in front of me. But at the same time it shows me in the dash if there's a car in front and how far it is(in seconds).
Any help appreciated.
Cheers!
