WARNING: This page is about a different car, the 2005 Dodge Durango. However, it is still accessible from the selected car via links, so may be relevant.

The Antilock Brake Module (ABM) is a microprocessor which handles testing, monitoring and controlling the ABS brake system operation.

The ABM is mounted on the top of the hydraulic control unit (HCU). The ABM operates the ABS system and is separate from other vehicle electrical circuits. ABM voltage source is through CKT A111 (fused B+).

NOTE: If the ABM needs to be replaced, the rear axle type and tire revolutions per mile must be programed into the new ABM. For axle type, refer to DIFFERENTIAL & DRIVELINE . For tire revolutions per mile, (Refer to TIRES/WHEELS/TIRES - SPECIFICATIONS) . To program the ABM, refer to ABS - SERVICE INFORMATION .
