Service bulletin 502

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

CHECK FOR LOOSE ALTERNATOR BOLTS.

IF THE ALTERNATOR BOLTS ARE LOOSE, TIGHTEN THEM AND TRY RESTARTING THE ENGINE. IF IT STILL WON’T START, THEN CHECK THE ECM/PCM CONNECTOR FOR BATTERY VOLTAGE AND GROUND. IF YOUR READINGS ARE GOOD, THEN REPLACE THE ECM/PCM."
