2006 Colorado Traction control not restoring engine to normal operation after one wheel spins excessively. The only way to get traction control to release control of the engine is to disconnect the battery cable and re-install. The engine will not reset even after letting idle after traction control takes over. Is there any other way to reset traction control? engine is 3.5 liter 5 cylinder.

That's normal operation for automatic traction control.

With some makes and models this is normal. The PCM will reduce engine power when the traction control senses wheel slip as a safety precaution until traction is restored

The traction control system DOES cut your engine power when the tires spin. That is by design. The system cuts engine power to stop the wheels spinning and restores power once the wheels regain traction. It feels odd when the tires spin and power cuts out. It's good practice to lift off the accelerator when the system kicks in. Otherwise, if you are on gravel or slick streets the tires may spin, stop when traction control kicks in, and then spin again when power is restored. It is not an "elegant" solution but it does work for the most part.

Traction assist is a measurement that compares the spin of one wheel to the spin of another. When a traction light is on, it means that the system is activated to make the two wheels spin at the same rate.

Traction control systems perform this in several ways. Some systems use independent braking to apply the brakes to the fastest spinning wheel. Other systems affect the engine so RPM is lowered and a combination of both methods may be used to brake one wheel while reducing engine RPM.

Now the spin counter can be mounted at each wheel or in the differential. Those that are mounted in the wheels are subject to debris like rust or brake pad material blocking the spin counters.

I can imagine the trans being tied into the traction system by limiting the trans from shifting into higher gears if the car thinks the wheels are already turning too fast.

Now I am not a Lexus Expert, but on Mercury systems the Traction Control has an on/off switch. If you go to alldatadiy.com or Autozone.com and register your vehicle for free. You will be able to get wiring and fusebox details. If the traction control system has its own fuse, pull it.

There is a good chance that with the traction control shut off, the car will shift normally. Then you can drive somewhere that can test the traction control and predict what is wrong.

The traction control system senses wheel spin from either drive wheel. Excessive spin sensed by the ABS sensor will force the wheel that is spinning to brake to avoid loss of traction. You could have a faulty ABS sensor (wheel speed sensor) As far as the engine "cutting off" Do you mean that it shuts off completely or you cannot accelerate?

TRACTION CONTROL: An enhancement of an existing ABS system that prevents wheel spin while accelerating on wet or slick surfaces. It uses the same wheel speed sensors to monitor wheel speed during acceleration, but requires some additional control solenoids and a pump to apply braking pressure to control wheel spin. The traction control system brakes the drive wheel that's starting to spin to shift torque to the opposite drive wheel that still has traction. Most traction control systems only operate at speeds up to about 30 mph. Additional control strategies that some traction control systems use to limit wheel spin include reducing the throttle opening, upshifting the transmission, retarding spark timing and deactivating fuel injectors.

Hope helps.

the TRACTION CONTROL SYSTEM is to stop the driven wheels from spinning on excessive acceleration,which would normally result in loss of traction from one or both wheels,like the abs but in reverse.

Traction control controls spin in wheels on slippery roads. if you are stuck in snow or ice or on slippery road surface,try switching the traction control system off. this may allow excess wheel spin to dig the vehicle out.

Hello Jeremy.
When your traction light comes on it is indicating wheel spin on acceleration. To prevent wheel spin an onboard computer reduces engine power to limit the wheel spin. Some, if not most, cars equipped with this feature will also apply the brakes if wheel spin continues after reducing engine power.
Hope this answers your question.
Thank you for using Fixya!

that is what it is desgined to do - reduce acceleration and apply the brakes intermittently when the wheels spin. You have a switch you cn push to disable it. You need to disable each time you start car. See owner manual.

DESCRIPTION AND OPERATION Traction Control System The optional traction control system is designed to control wheel spin when accelerating on slippery or loose surfaces. Traction control system is available only with anti-lock brakes. The traction control system includes the following components:

• Hydraulic control unit.
• Throttle control actuator (9N825).
• Traction control switch.
• Traction control warning indicator.
• Front brake anti-lock sensor (2C204).
• Rear brake anti-lock sensor (2C190).

The traction control system operates as follows:

• System functions by transferring torque from the spinning wheel to the wheel with the most traction.
• This is achieved by applying the brake at the spinning wheel through the hydraulic control unit or reducing the throttle opening.
• Traction control braking and throttle control occur at vehicle speeds up to 50 km/h (30 mph).
• At vehicle speeds above 50 km/h (30 mph), only throttle limiting control is used.
• If speed control is operating when traction control system engages the traction control system will disengage speed control through the use of a speed control relay. This action is the same as applying the brake pedal with speed control engaged.

Traction Control Switch The traction control switch is located on the instrument panel, left of the steering column.
