Check electrical connections for obvious damage, shorts, or opens.
3. If the inspection reveals obvious concerns that can be readily serviced, correct the concern before continuing with Inspection and Verification.
4. If the concern remains after the inspection, connect the Rotunda New Generation Star (NGS) Tester 007-00500 or equivalent to the data link

If the DATA LINK DIAGNOSTICS test is passed for the lighting control module, retrieve continuous DTCs and execute Self Test Diagnostics for
the lighting control module to retrieve current DTCs.
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 (LCM) Diagnostic Trouble Code (DTC) Index to continue diagnostics. See:
Component Tests and General Diagnostics/Lighting Control Module Diagnostic Trouble Code Index
7. If the lighting control module(s) cannot be accessed by the NGS, GO to Pinpoint Test A. See: Pinpoint Tests/Test A : No Communication With
Lighting Control Module
