There is no specific control module for traction control. It works by the engine controller and ABS controller communicating with each other. If the ABS controller detects that a driving wheel sensor is noticably faster than the others and the brake pedal is not being applied it knows that the driving wheel/s are spinning. The engine controller then reduces the engine power output accordingly. This operation cannot be properly performed if there is any kind of malfunction on either the engine or ABS systems, including the MAF.....

cheers very useful info there
