First make sure the DRBIII® is communicating with the CAB. 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 DIAGNOSTIC INFORMATION AND PROCEDURES and begin to diagnose the symptom.

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