Traction Control System

I have a 2001 silhouette and the Service Traction System message displays in the message center and the Traction System is turned off. I have noticed that this only happens when the headlights (not the running lights) are on and the van is in reverse or you use the right blinker. The dealer told me that my transmission was slipping and need to be rebuilt, it does not SLIP. Any suggestions on where to look for this problem.

Take a look at the circuit boards for the brake lights bulbs. Check for melting of the plastic where the bulbs connect. Check all of the bulbs (brake, reverse, turn signal) for melting at the circuit board. Strange things happen to the electrical system when there is a problem with these boards.

Does your cruise control still work?

If you need new circuit boards you can buy "new" circuit boards on Ebay.

Welcome to the forum!

Sounds like the DEALER is trying to get your money.

I believe the Traction Control system is part of the BRAKING system, not the transmission.

I did find a TSB (Technical Service Bulletin) that applies to 2000-2005 GM minivans & a couple other GM vehicles. The TSB is #01-08-45-005B and is dated Oct. 14, 2004.

It mentions some possibly corroded or bent pins in connector C305, which is located on the floor to the rear of the driver's seat. You should be able to see the connector from BELOW the van (outside).

It says that water may get into the connector (from inside or outside) and cause the pins to corrode, or that the female terminals of connector may have spread apart and causing intermittent connections.

I'm thinking that this could possibly be the problem because this only happens when you are drawing extra power (to run lights, blinkers, etc.), and a poor connection would tend to show up under those conditions.

Almost forgot: this connector carries signals from the EBCM (Electronic Brake Control Module) and the fuel system.

Let us know what you find.

Take Care,

Just thought I'd throw in my two cents worth. I have a 2002 olds silhouette and had the same problem with my traction light coming on and no cruise control. Had the two rear circuit boards replaced in the tailights. Cost was $42.39 a piece. that fixed the cruise control. For the traction control light coming on they replaced a melted brake switch. cost was $10.52 for the switch. Should mention that I had the work done at the local gm dealer and the price is without the labor . Hope this helps anybody
