Preliminary Inspection

WARNING: This page is about a different car, the 2002 Chevrolet Monte Carlo and 2002 Chevrolet Impala. However, it is still accessible from the selected car via links, so may be relevant.

Verify customer complaint by operating suspecting system. Visually inspect for obvious signs of mechanical and electrical damage. Inspect for blown fuses and damaged relays. For Impala fuse and/or relay identification, see FUSES & CIRCUIT BREAKERS article in ELECTRICAL. For Monte Carlo fuse and/or relay identification, see FUSES & CIRCUIT BREAKERS article in ELECTRICAL.

Inspect for loose or corroded connections, damaged wiring harnesses and/or switches. Check for a broken or partially broken or partially broken wire inside insulation, which could cause system malfunction but prove good in a continuity/voltage check with system disconnected. Ensure any aftermarket electronic equipment is properly installed. If fault is found, repair as necessary. If no fault is found, perform self-diagnostics. See SELF-DIAGNOSTIC SYSTEM .
