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 Tester, 007-00500 or equivalent to execute Self Test Diagnostics for the generic electronic module (GEM).
5. If self test is passed and no diagnostic trouble codes (DTCs) are retrieved, go to the Symptom Chart to continue diagnostics. Diagnosis by Symptom
6. If diagnostic trouble codes (DTCs) are retrieved, go to the GEM DTC Index to continue diagnostics. Generic Electronic Module DTC Index
7. If the generic electronic module (GEM) can not be accessed by the New Generation Star (NGS) tester, GO to Pinpoint Test A. A: No Communications With Generic Electronic Module
8. Rotunda Service Bay Diagnostic System (SBDS) 001-00001 or equivalent, may also be used to diagnose this system.
