That is the Acceleration Slip Regulation; It works with your Anti lock Brake/Traction Control system. The ASR monitors the Steering angle sensor & Accelerator position sensor. Wheel speed is continuously monitored by the ASR module. It controls the braking of the rear wheels when it has noticed a slipping of the wheels until the slip has been corrected. It does not plug into the transmission. It is used to turn off the traction control.
Acceleration Slip Regulater,It is for traction control should be plugged into the trans..it may be malfunctioning.
