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.
Preliminary Inspection
Verify the customer's original concern. Check electrical connections for obvious damage, opens or shorts. Inspect terminals No. 2 (Tan/Orange wire), No. 7 (Light Blue/White wire) and No. 10 (Pink/Light Blue wire) on the data link connector for loose, bent, deformed, corroded or broken terminals. If terminal is damaged, service or replace terminal, verify communication with Rotunda New Generation Star Tester (007-00500) or equivalent. If the concern(s) remains after the inspection, continue with New Generation Star Tester Driven Diagnostics. See SELF-DIAGNOSTIC SYSTEM .
