Preliminary Inspection

Verify customer's complaint by observing indicators and gauges to determine correct operation with ignition switch in ON position and engine off. Check for stuck gauge needle. Check for low brake fluid level, low coolant level or low engine oil level. Check for damaged engine oil filter and/or oil pump, fuel tank, Hybrid Electronic Cluster (HEC), vehicle speed sensor and worn or damaged generator drive belt.

Check for damaged wiring harness, loose or corroded connections, or damaged switches and sensors. Check related Central Junction Box (CJB) fuses. See WIRING DIAGRAMS . CJB is located under left side of instrument panel, near left kick panel.

Check function of charging, cooling, engine oiling, and fuel delivery systems. Repair or replace as necessary. If no problems are found, check for Diagnostic Trouble Codes (DTC). See SELF-DIAGNOSTIC SYSTEM . If no DTCs exist, diagnose by symptom. See SYMPTOM INDEX  table under SYSTEM TESTS.
