RAM 1500 Truck 4WD V8-5.7L VIN D (2005)
Electronic Brake Control Module: Description and Operation
The Antilock Brake Module (ABM) is mounted to the Hydraulic Control Unit (HCU) and operates the ABS system.
The ABM voltage source is through the ignition switch in the RUN position. The ABM contains a self check program that illuminates the ABS warning
light when a system fault is detected. Faults are stored in a diagnostic program memory and are accessible with the DRB III scan tool. ABS faults remain
in memory until cleared, or until after the vehicle is started approximately 50 times. Stored faults are not erased if the battery is disconnected.
NOTE: If the ABM is being replaced with a new ABM is must be reprogrammed with the use of a DRB III.
