If concern remains after inspection, 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). See MODULE COMMUNICATIONS NETWORK article.
If self test is passed and no trouble codes are retrieved, go to SYMPTOM CHART table to continue diagnostics. See SYMPTOM CHART table. If DTCs are retrieved, go to MODULE COMMUNICATIONS NETWORK article. If GEM cannot be accessed by NGS, go to pinpoint test "A". GEM is located behind instrument panel, to left of steering column.
