Electronic Brake Traction Control Module (EBTCM)

The EBTCM is located in the LH side of the engine compartment and is mounted to the lower rail.

The EBTCM receives a vehicle speed signal from the left rear Vehicle Speed Sensor (VSS). The VSS produces an AC signal when the rear axle shaft rotates. The frequency of the signal is proportional at which speed the shaft rotates. The shaft speed is proportional to the speed of the vehicle.

The EBTCM processes the VSS signal and transmits the processed speed signal to the ECM.
