These procedures include all the specifications, instructions, and graphics needed to diagnose Dodge Truck Kelsey-Hayes EBC 325 Antilock Brake System (ABS) and Rear Wheel Antilock (EBC 2) System problems. The diagnostics are based on the failure condition or symptom being present at time of diagnosis.

Follow the recommendations below when choosing your diagnostic path.

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

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

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

Diagnostic procedures change every year. New diagnostic systems may be added; carryover systems may be enhanced. READ THIS Information BEFORE TRYING TO DIAGNOSE A VEHICLE DIAGNOSTIC TROUBLE CODE.
