VT ex-cop Traction control issue!

[t-rav]

hey guys
my mate has an ex cop VT it has traction control and when it also has lsd this is simply unacceptabe and it needs to be switched off ....

BUT....

It has no tracton control button, no fuses or relays that are marked to have anything to do with traction control and its not linked up with the abs either as we have pulled out and played with all the fuses and relays and nothing will turn it off

Does any one have any idea how we can fix this problem
any help would be great

[walesy]

dont try pull out relays or fuses im pretty sure its linked with the abs...

[t-rav]

well we took out the ABS fuse and that stopped the abs from working but traction still stayed on .....

[walesy]

oh ok i thought they were linked... an auto electrician might be able to put a switch in? ... it does come in handy having a button for it.. as u can see in my avatar

there is no traction control on Police Vehicles.


heres what they do have though:

section 218 - Is there already a National Police Car

[fitz_vt]

yeah every police vehicle i have seen in VT/VX does not have traction control as they were executives with the Police Pack in them

[t-rav]

well its a police pack its manual says so and so do the engine plates, it has the the fuses and wiring for all the lights and it has traction control haha it'll spin for about 1.5meters and then will grab and no more loss of traction on dirt,wet road and or grass....
either foot to the boards or keeping it in 1 on the auto ???
anyway i dont think wer gonna figure it out
thanks for the help anyway guys

ABS and TCS Control Module are the same according to the Holden Workshop manual and my gregory's one as well.

ABS works off of a Fusible Link in the engine bay and fuse 27, TCS works off of the ABS module.
The way TCS works is by applying brake pressure to the certain brakes that have lost traction, though the ABS modulator, upon the wheels braking, the vehicle regains traction. there are also various torque sensors throughout the vehicle and attached to the engine these sensors provide data to the central unit at the ABS module so that when ABS is turned off Traction Control is turned off too. so if you take out the ABS/TCS Fuse Fuse number 27, it should not operate.

Sell the car and buy one with a switch for traction control.

go to someone that tunes cars they should be able to turn it off permanently

[fatboy15]

hey i have an ex cop vt commodore aswell and let me tell you they have tractin control like hell. and it cant be turned off unless you go to ultra tune and get them to permantly disable traction, then good luck with taking corners fast :P

Sounds like you need better tyres/suspension.

The only recommended way of disabling the ETC system is to disconnect terminal 27 from the ABS/ETC Control Module connector YE98, circuit 1427, Black/White wire (actual torque). This is to be achieved by withdrawing terminal 27 from connector YE98 and taping the wire back to the main wiring harness. This will disable the ETC system while maintaining normal ABS operation.
If the ETC system is disabled, the TRAC OFF warning lamp in the instrument cluster will be permanently illuminated when the ignition is on and Diagnostic Trouble Code 74 will be logged. At no time must the ‘TRAC OFF’ warning lamp be disconnected as its function is to advise the driver that this safety feature is not available.

are you sure it has traction control and your just not used to a heavy car with an lsd and probably alot of rubber?

[buzuki]

cut pin B11 at ecu, black/white trace.

that will disable traction control (if it has it) the wire will be there if it has it or not, this will also illuminate the light on dash permanently,

thanks mate great help

[canabl]

just reading through this question, my vt senator manual is the same thing, you can rev it dump it and just get a little chirp from the tyres.
this wire that can be cut/disconnected, i guess you could put in a switch of your own so as to be able to activate in times of need like wet weather or on the track?
did this fix the non wheel spinning issues for anyone?

[GMMAD]

if it doesnt have a TC switch it hasnt got it
more like torque management I would say

[GMMAD]

go to someone that tunes cars they should be able to turn it off permanently

its not in the tune

[rlnhrd276]

does this remove torque management on vt 5.0 that has no trac cntrl?

it'll spin for about 1.5meters and then will grab and no more loss of traction on dirt,wet road and or grass....
either foot to the boards or keeping it in 1 on the auto ???... I hope your not doing this on public roads.......

No he saves this sort of activity for foot paths and playgrounds.
