Trouble Shooting Hints: Notes

On all models, note condition of SECURITY indicator light. If indicator stays on or flashes continuously, see appropriate ANTI-THEFT SYSTEMS article in ACCESSORIES & EQUIPMENT. 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 appropriate SELF-DIAGNOSTICS article in ENGINE PERFORMANCE.
