Anti-Lock Brake System Module - Description
DESCRIPTION
The Antilock Brake Module (ABM) is a microprocessor-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 or Electronic Stability Program (ESP) 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.
The ABM (1) is mounted to the HCU (2) as part of the Integrated Control Unit (ICU). The ICU is located in the engine compartment on the inboard side
of the right body frame rail behind the strut tower. For information on the ICU, See: Brakes and Traction Control/Antilock Brakes / Traction Control
Systems/Hydraulic Control Assembly - Antilock Brakes/Description and Operation/Integrated Control Unit (ICU) - Description - DESCRIPTION).
