ve ss temp guage not working

Sounds like you've got a problem with a module locking up the CAN BUS line, need to have the trouble codes checked and work out which ones giving you trouble

The Can bus is the data network that all the modules in the car use to communicate. In VE's theres a low speed network for comfort items such as HVAC, Radio etc and a high speed network for engine/ABS/ESP etc.

It may simply be a failed temp sensor. Ill check out the schematic and get back to you.

 

The IPC displays the engine coolant temperature as determined by the engine control module (ECM). The IPC receives a GMLAN message from the ECM indicating the engine coolant temperature. The IPC engine coolant temperature gauge only displays coolant temperatures greater than 60°C. The engine coolant temperature gauge defaults to 60°C or below if:

• The ECM detects a malfunction in the engine coolant temperature sensor circuit.
• The IPC detects a loss of GMLAN communications with the ECM.
• The body control module (BCM) detects a loss of GMLAN communications with the ECM.

Basically the sensor itself may have failed, or as said above a loss of comms. Need to check DTCs with a scan tool.

 

Any workshop with a scan tool can read the codes.

 

Hi there,

Had the same thing happen to my Calais this morning. Have checked all fuses and relays and all seem fine. Im hoping that mine will start in the morning and the problem will be gone.

 

Hi just for info, my calais had reset its self over night and no problem since.

 

self fixing cars lol

 

'07 Lumina SS (in Bahrain)...I've been having the same problem off and on for the past couple of weeks. The "Contact Dealer" message displays, then my A/C and temp guage stop working. After driving for a while and (sometimes) after sitting over night it goes away and everything is fine. Had it in the dealer last week and, of course, it wasn't malfunctioning and they didn't know what I was talking about.

 

I had the same problem with my 2008 VE ssv ute. At first it came up with contact dealer and service which went away a couple of times but then came back all the time with a check engine light. I bought a coolant temp sensor off eBay for $36 and fitted it. Took 10 mins and problem hasn't come back for over a week now. I disconnected the battery while I did it to reset the codes. I did try disconnecting the battery before hand but the problem came back straight away.

 

Hi,
Having the same problem as you all.
Codes are throwing out a faulty temp sensor so had it replaced at a mechanic and it still has not fixed the problem. Had an auto electrician look at it and $200 later he was useless. Can anyone please help me out with this issue, its driving me nuts as i can't even pay to get it fixed.
Thank you

 

Holden only charge $120 to plug their Tech2 scanner in and find the problem. Nothing against auto electricians but they are kind of useless when it comes to this type of problem. Been there and done that before.

 

Yea he had no idea, do you think Holdens scanner would be different to the standard mechanic/auto elec scanner?
Thanks mate

 

I have to agree. Unless you know a Auto electrician for cheap. Its better to go Holden or a Mechanic with a scan tool that has a bit of knowledge with Holden's.

 

It's not the fact that they have different scan tools or not, it's the fact that Holden have seen every possible problem with these cars and know what the problem is 99% of the time and have the know how to repair it. Don't get me wrong here, I am not a fan of Holden dealers as they over charge for most of their work but unless you know an ex Holden mechanic somewhere else, you are limited to where you can go. I have had problems in the past with other holders and spent weeks dicking around with small workshops and paying a fortune and in the end I still had to take it to Holden because the other mechanic could not fix it. So now unless it's a simple job like oil change or brake pads my car goes to Holden.

 

Hi everyone, problem was solved.. ending up being the thermostat.
Scan tools couldnt pin point it so i went with my gut feeling and changed the thermo so far so good.
Thanks for everyones advice.
