1. Verify the customer's concern by operating the parking lamps to duplicate the condition.
2. Inspect to determine if one of the following electrical conditions apply:
VISUAL INSPECTION CHART
-
Damaged headlamp switch.
-
circuitry open/shorted.
-
Bulb burned out.
-
Damaged connector.
3. If inspection reveals an obvious concern that is readily serviced, correct the concern before continuing with Inspection and Verification.
4. If a concern remains after the inspection, use Rotunda New Generation STAR (NGS) Tester 418-F048 (007-00500) or equivalent connected to the
Data Link Connector (DLC) to retrieve continuous Diagnostic Trouble Codes (DTCs) and to execute Self Test Diagnostics for the Lighting
Control Module. If, after performing data link diagnostic test, the NGS Tester responds with NO RESPONSE/NOT EQUIPPED, go to Pinpoint
Test AA. See: Headlamp/Testing and Inspection/Component Tests and General Diagnostics/Pinpoint Tests/Test AA: No Communication With
Lighting Control Module
5. If self test is passed and no DTCs are retrieved, go to the Symptom Chart to continue diagnostics. See: Symptom Related Diagnostic Procedures
6. If DTCs are retrieved, go to the Lighting Control Module Diagnostic Trouble Code (DTC) Index to continue diagnostics. See: Diagnostic Trouble
Code Descriptions/LCM Diagnostic Trouble Code (DTC) Index
7. If the lighting control module cannot be accessed by the NGS Tester, go to Pinpoint Test AA. See: Headlamp/Testing and Inspection/Component
Tests and General Diagnostics/Pinpoint Tests/Test AA: No Communication With Lighting Control Module
Rotunda Service Bay Diagnostic System (SBDS(R)) 418-F001 (001-00001) may also be used to diagnose this system.
