The Antilock Brake Module (ABM) is a microcontroller-based device which monitors the antilock brake system (ABS) during normal braking and controls it when the vehicle is in an ABS stop or when in a traction control situation. The ABM utilizes a 47-way electrical connector on the vehicle wiring harness. The power source for the ABM is through the ignition switch in the RUN or ON position.

NOTE:

The ABM is only separately serviceable for non-HSA (Hill Start Assist) equipped vehicles. Do not remove the ABM for vehicles equipped with HSA.

The ABM (1) is mounted to the HCU (2) as part of the Integrated Control Unit (ICU). The ICU (3) is located in the engine compartment below the master cylinder on the front suspension cradle/crossmember. For information on the ICU. Refer to INTEGRATED CONTROL UNIT (ICU), DESCRIPTION .
