Traction control flash up and doesn`t work

[Black_Supra]

Hey guys,

 

got a problem with my car (96 TT 6)

 

Since some weeks the Traction Control flash up all the time i drive the car. It even doesn`t work.

 

Furthermore the Control Light (red exclamation mark) flashs up when i drive more than 60 MPH and then it stays until i restart the car. Maybe this is another Problem but i just wanted to let you know.

 

When i start the car the Stepper Motor opens/closes the TB 30 times in ~1 second distance. You can hear the TB slapping against the TB Body.

 

 

What i did:

 

Checked the TRC switch in the interior - it`s okay.

 

Checked the Stepper Motor at the TB - it works fine.

 

Checked all fuses - they are even okay.

 

 

 

So what it could be? Anybody got a idea?

 

 

thanks in advance

You could see if you have any error codes, that'll let you know if its a faulty ABS sensor. If the ECU does say speed sensor fault then you need to unplug the sensors and check there is a resistance across the sensor leads of several thousand ohms to point to which sensor has failed. If there is no resistance or no circuit the sensor or wiring or pickup ring has failed.

it flashes when theres a prob with trac control. ie trac motor not working, butterfly jamming open etc

 

You could take it off and give it a clean up followed by a battery disconnect ECU reset and see if that resolves the problem.
