Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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). See MODULE COMMUNICATIONS NETWORK article.
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.
