Auto traction and cruise control problems

I have the same problem few days ago, and still didn't find any solution. Can any one please help?????20

Unsafe to drive the van - probably not unless you are relying on the traction control system. There is an issue somewhere with the traction control system that needs to be diagnosed and repaired. Generally this requires special tools that your local trusty auto repair facility should have. They can help diagnose the issue and recommend a course of action for you.

check the abs sensors common to hit or damage the wiring or knock connection loose when doing a brake job the traction control system[tcs] is tied into the abs system

the traction control system watches wheel speed thru the wheel speed sensors. it was designed to aid in traction in slippery conditions. when one of the wheels loses traction and the system sees an abnormal insrease of speed in one of the wheels the system will activate and derate the power to avoid wheel slippage. going around a corner the outside wheel will spin faster then the inside wheel. under normal acceleration nothing will happen, however under heay acceleration you may be causing a wheel to break free, especially on wet roads. you could have a speed sensor problem but i would expect you would also have an antilock problem. try a slower acceleration around corners then try a heavy acceleration, if it was ok on normal acceleration but activated on heavy acceleration then your going to have to lighten up on the pedal a bit. otherwise the system should be scanned for codes. i never liked this system much and it wasen,t around too long. good luck!

those lights come on when the system is shut down by the computer. You have to scan the abs system. It is usually one of the sensors. I have seen many of the front wheel bearings being the problem because the sensor is built in and when the bearing goes bad.

The ABS and Traction control both work off the abs system .

Hope this helps.

use a scanner to check the abs system . most of the time the abs brakes and traction control system work together. your cruise control . unit has a servo motor .in front right fender well. check the fuse and relay also the cruise control brake release switch. and the brake light switch.if all is good you have a cruise control module problems. dealer ship job.

wheel bearing about to go bad.. Notice any slight roaring noise??

Sounds like you have a problem in the front brakes or a front wheel speed sensor. A common cause for a Traction light is a faulty front ABS wheel speed sensor or harness. When the Anti lock brake computer sees a problem in the ABS syetm, it disables traction control as well.

The first thing i would check is all 4 abs sensors at the wheels.You can do this with a volt meter set on ac voltage and spin the wheel if it generates voltage at all on the meter its good.

I agree with the post about the tail lights. And the symptom about the brakes on when starting was also helpful. When I took off my rear tail lights and removed the top light bulb (top of the 4 is closest to connector) then repeat starting the car the problem is gone. I have a whole drawer of these bulbs that I removed, not because the filament was burned out, but because the base (similar to circuit card edge connector) had heat damage and melted. I am not sure exactly what the problem is but I think there are multiple conductors in the fixture which are too close or get moisture shorts. Anyway I hypothesize the circuit for daytime running lights is leaking current into the brake light circuit, and it causes that module that controls traction control and ABS to declare a fault. When you start with foot on the brakes the brake lamp is pulled on (I don't know if switches hi or lo) so that module doesn't declare the fault until you release the brakes.

I put in new bulbs and it works fine for now, but I know it may reappear some day then I will repeat, disassembly of the fixtures and inspect bulb bases for heat damage and clean out and replace. That is what did the trick for me.
