Retrieving Trouble Codes
Use New Generation Star (NGS) Tester (007-00500) connected to Data Link Connector (DLC), located below instrument panel at right of steering column, to retrieve Diagnostic Trouble Codes (DTCs) and execute self-test diagnostics for Generic Electronic Module (GEM).
If self-test passed and no trouble codes are retrieved, go to appropriate test to continue diagnostics. If DTCs are retrieved, go to appropriate test.
