WARNING: This page is about a different car, the 2004 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.

The procedures contained in this article include all the specifications, instructions, and graphics needed to diagnose the AN Chassis system problems: TRW EBC 125 Rear Wheel Antilock (RWAL) and EBC 325 Antilock Braking System (ABS) . The diagnostics in this article are based on the failure condition or symptom being present at time of diagnosis.

Please follow the recommendations below when choosing your diagnostic path.

First make sure the DRBIII® is communicating with the vehicle system being diagnosed. If the DRBIII® displays a "No Response" condition, you must diagnose that first.
Read DTC's (diagnostic trouble codes) with the DRBIII®.
If no DTC's are present, identify the customer complaint.
Once the DTC or customer complaint is identified locate the matching test in the Table of Contents and begin to diagnose the system.

All component location views are in COMPONENT LOCATIONS . All connector pinouts are in CONNECTOR PINOUTS . All schematics are in SCHEMATIC DIAGRAMS .

An asterisk (*) placed before the symptom description indicates a customer complaint.

When repairs are required, refer to the appropriate article for the proper removal and repair procedure.
