ANTILOCK BRAKE MODULE DESCRIPTION The Antilock Brake Module (ABM) is a micropro- cessor-based device which monitors the antilock The ABM is mounted to the HCU as part of the Integrated Control Unit (ICU) (Fig. 1). The ICU is (INTEGRATED CONTROL UNIT) - DESCRIPTION). OPERATION The primary functions of the Antilock Brake Mod- ule (ABM) are to: • Monitor the antilock brake system for proper operation. • Detect wheel locking or wheel slipping tenden- cies by monitoring the speed of all four wheels of the • Control fluid modulation to the wheel brakes while the system is in an ABS mode. • Store diagnostic information. • Provide communication to the scan tool while in diagnostic mode. • Illuminate the amber ABS warning indicator lamp. • (With traction control only) Illuminate the TRAC ON lamp in the message center on the instrument • (with traction control only) Illuminate the TRAC OFF lamp when the amber ABS warning indicator The ABM constantly monitors the antilock brake system for proper operation. If the ABM detects a NOTE: If the vehicle is equipped with traction con- The ABM continuously monitors the speed of each wheel through the signals generated by the wheel The ABM contains a self-diagnostic program that monitors the antilock brake system for system faults.
