Flash computer 2010 chevy equinox Abs, traction control, ck engine lights all come on. Vehicle goes into "safe" mode Drives at about 5 mph until I turn off & restart after 5 mins


Probably caused by the electronic throttle control . How many miles on the vehicle ? The gas pedal has position sensors that the PCM - engine computer uses to know how much to open the throttle plate .
Drive by Wire Function and diagnostics by Wells
What engine ?
The throttle actuator control (TAC) system is used to improve emissions, fuel economy, and driveability. The TAC system eliminates the mechanical link between the accelerator pedal and the throttle plate. The TAC system eliminates the need for a cruise control module and idle air control motor. The following is a list of TAC system components:
• The accelerator pedal assembly includes the following components:
- The accelerator pedal
- The accelerator pedal position (APP) sensor 1
- The APP sensor 2
• The throttle body assembly includes the following components:
- The throttle position (TP) sensor 1
- The TP sensor 2
- The throttle actuator motor
- The throttle plate
• The engine control module (ECM)

I loose power when traction control light comes on in my 2002 mustange gt


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

Low traction light


sounds like failed wheel speed sensors. you can get around this by turning off traction control until you can get em fixed. If you hold in the the traction control button, it should shut the system down

ASR - Acceleration Skid Control system.
When ASR warning light blinking the system is activated itself for car acceleration skid control.

For today's typical high-torque engines, traction control (ASR) can increase both comfort and safety, particularly when driving on slippery roads or surfaces offering differing levels of grip. Traction control permits smooth starting and acceleration through the full speed range without wheel-spin or fishtailing.

ASR only operates in conjunction with the electronic accelerator (E-gas) and uses components of the anti-lock braking system (ABS). If one wheel suddenly begins to rotate faster than the others (slip), ASR intervenes in the engine management system and reduces power until the wheel stops spinning.
The ASR system represents a further contribution to active safety as it maintains vehicle traction and directional stability throughout the acceleration phase at any speed. In addition, it reduces tyre wear. Activation of the ASR system is indicated by a flashing indicator lamp in the instrument cluster.
The ESP system means the Electronic Stability Program. If the ESP lights on the dashboard permanently the ESP system is faulty. You must access the ESP Electronic Control Unit (ECU) memory for pull out all DTC (Diagnostic Trouble Codes), using diagnostic equipment connected to the data link connector of the car. Then you will be full informed about bad pieces (e.g.: front right wheel abs sensor interrupted, ...). After bad pieces replacement you will be able to erase all faults memored by ESP ECU, in other words reset the ESP system and turn off the warning lamp on dashboard.

I just recently purchased a 2007 Ford Focus SES that had only 75000 km. I have never driven a car with traction control on it. We had a snow storm, and when I accelerated to about 45 km per hour, I had a...


All vehicles will slide in the snow. Traction control or not. What traction control does, in simple terms...Is when your wheel start to slip, which is detected by some sensors, it lowers the vehicles throttle position, slows the RPM's down, even if your foot is still on the gas, for a matter of seconds, until the wheels stop slipping. So when you feel or hear your vehicles engine slowing down on its own, its best to just let off the gas and let it go for a couple seconds. A way to test the traction control...From a stop, if you are in the snow, and you push the gas down a good bit, make it spin, and the vehicle should seem to power down on its own, while the light comes on, if it does not do this, then traction control would not be working. Hope this helped.

Traction Control problem


I would pull the fuse. I do not like traction control or abs personally and I pull the fuse on both. They tend to have problems in their circuits and the pumps and I do not trust them

Traction control helps limit tire slip in acceleration on slippery surfaces. In the past you had to feather the gas pedal to prevent the drive wheels from spinning wildly on slippery pavement. Many of today's vehicles employ electronic controls to limit power delivery for the driver, eliminating wheel slip and helping the driver accelerate under control. Don't turn it off.
