Traction Control

[bowtie123]

Hi,

2005 Deville DTS.

Traction Control Light will come on.

Does not come on when the car is first started.

When driven a short distance and cut off, then

restarted, the traction control light will be on.

The console switch does not seem to make a difference.

No Codes are set!

Thanks for any info.

Bowtie,

First, a nice looking ride!

I thought the 2003 and newer Caddys do not have a user-interface for reading diagnositc codes from the dash, (as in OBD-1 and OBD-2 generations).

Therefore, if you note that "no codes are set", do you really mean that no new messages appear on the dash when the Service Traction Control light comes on?

If the above is correct, then perhaps a code has already been set, such that you will need to have it read by a "Tech 2" device by a Dealer or someone that has the proper connections etc.

You probably already know that many inputs can cause issues with the traction control and/or stability system. For example, seemingly mundane things like different/low/high tire pressues and brake pad wear can trigger stability/traction control codes and perhaps disable speed over 90MPH.

These are basically computers, with a vehicle for an option.

Good luck,

The "mods" to the car were done before I brought it.

I would have only done the roof and gold package.

Have come to like it more as time goes by.

The car has the full diagnostic system, which checks the codes

on 20 different computers.

Most of the codes I get are loss of communication related to the "Drivers Door Module"

I do have one rear tire that is about 3 lbs. lower than the others so

I will bring it up tomorrow and see if it makes a difference.

Thanks again,

Bowtie

There are lots of OBD II code readers out there with prices varying from under $100 to the $500 range. The best are intended for independent mechanics or serious do-it-yourself types and are PC based, with the hardware being a cable and an expansion card for the PC. The Tech 2 is designed for GM dealers and is very expensive. I have one of the $100 code readers and find it useful for quick checks of my wife's Pontiac and a friend's Toyota.
