Trouble Shooting Hints
On all models, note condition of SECURITY indicator light. If indicator stays on or flashes continuously, see appropriate ANTI-THEFT SYSTEM article in ACCESSORIES & EQUIPMENT section:
- ANTI-THEFT SYSTEM - DeVille & Eldorado
- ANTI-THEFT SYSTEM - Seville
Check starter solenoid terminals and battery grounds. Check for proper installation of aftermarket electronic equipment. Perform self-diagnostic system test, to be certain no trouble codes are stored in PCM memory which may lead to misdiagnosis. See TESTS W/CODES article in ENGINE PERFORMANCE.
Check for open 50-amp BATT1 fuse and 30-amp BATT2 fuse. If ether fuse is open, check for a short to ground in Purple wire between starter enable relay connector terminal "E" and starter solenoid terminal "S". Also check for short in Yellow wire between ignition switch and park/neutral position switch connector C1, terminal "G". Check for BATTERY VOLTS LOW, BATTERY NO CHARGE or SERVICE ELECTRICAL SYSTEM massages on instrument panel. Check Instrument Panel Cluster (IPC) and Power Control Module (PCM) for related trouble codes.
