Body Control Modules: Diagnosis Dodge Durango I

PRETEST INSPECTION

Before proceeding with TROUBLE SHOOTING, SELF-DIAGNOSTIC SYSTEM, or SYSTEM TESTS, the following precautions must be followed

1. Vehicle must have a fully charged battery and functional charging system.
2. Always start at «RETRIEVING DIAGNOSTIC TROUBLE CODES (DTC)»(ref-3317-S34789037982000072100000) under SELF-DIAGNOSTIC SYSTEM. Starting with any other test may result in incorrect results.
3. Only perform test steps indicated. It is NOT necessary to perform all steps in a test.
4. Turn ignition switch to OFF position before disconnecting any module, or before connecting components.
5. Use extreme care when connecting or disconnecting components during testing to prevent accidental grounding or shorting.
6. DO NOT use a test light in place of a DVOM, unless instructed to do so.
7. Always disconnect scan tool after use or when disconnecting/charging battery.
8. Always perform appropriate VERIFICATION TEST after repairs are made.

SELF-DIAGNOSTIC SYSTEM

Note. Self-diagnostic procedures are written specifically for use with Chrysler's Diagnostic Readout Box (DRBIII(R)) scan tool. Other generic scan tools can be used, but may have limited functions.

RETRIEVING DIAGNOSTIC TROUBLE CODES (DTC)

1. Generic Scan Tool - Refer to scan tool manufacturer's instructions and procedures. Scan tools may not have ability to measure voltage, resistance or continuity. When instructed, use of an additional DVOM may be required.
2. DRBIII(R) Scan Tool - DRBIII(R) scan tool is grounded through Data Link Connector (DLC) connector. Only one volt/ohmmeter test lead is required when instructed by testing to measure voltage or resistance on specified circuit using DRBIII(R). DRBIII(R) scan tool volt/ohmmeter mode should only be used when system tests require use of this option or when prompted by DRBIII(R) scan tool. NOTE: Refer to DRBIII(R) scan tool manufacturer's instructions to retrieve and clear fault messages and when performing other DRBIII(R) scan tool functions.
3. Connect scan tool to Data Link Connector (DLC) 16-pin connector. See «COMPONENT LOCATIONS»(ref-3317-S16495408522000042500000) . Turn ignition switch to ON position. If scan tool LEDs do not illuminate and no sound emitted, check for poor cable connections. Check for a minimum of 11 volts at DLC connector terminal No. 16, and repair power supply as necessary. If scan tool display remains blank, consult scan tool manufacturer's manual. If scan tool LEDs illuminate and sound is emitted, continue with fault message and code retrieval.
4. Using scan tool, select SYSTEM MONITORS, then CCD BUS TEST. Scan tool will perform a CCD bus test. If scan tool displays BUS OPERATIONAL, go to next step. If scan tool displays any message except BUS OPERATIONAL, go to appropriate procedure for message displayed. See «SYMPTOM INDEX DIRECTORY»(ref-3317-S12923901372000042500000) table. If scan tool displays any CCD bus fault message or any NO RESPONSE message, it must diagnosed before proceeding with any other diagnostics.
5. Using scan tool, select READ DTCs. If any Diagnostic Trouble Code (DTC) message is present, go to appropriate procedures for DTC message(s) displayed. See «DTC MESSAGE INDEX DIRECTORY»(ref-3317-S30205649732000072400000) table. If no DTC messages are present, identify customer complaint and diagnose by symptoms present. See «SYMPTOM INDEX DIRECTORY»(ref-3317-S12923901372000042500000) table. When diagnosing a system with many apparent problems, a sequence of tests may be required. After repairs, ensure all problems or failures have been corrected. Perform appropriate VERIFICATION TEST.
