"SERVICE NEWS ARTICLE - TROUBLESHOOTING A VEHICLE FOR ANY OR ALL OF THESE SYMPTOMS?
• THE ENGINE CRANKS, BUT WON’T START.
• THE MIL COMES ON.
• THE IMMOBILIZER SYSTEM INDICATOR BLINKS WHILE THE ENGINE CRANKS.
• THE HDS CAN’T COMMUNICATE WITH THE ECM/PCM.
CHECK FOR LOOSE ALTERNATOR BOLTS. IF THESE BOLTS ARE LOOSE FOR ANY REASON, SUCH AS THE ALTERNATOR WAS SERVICED OR AN ACCESSORY A/C WAS INSTALLED ON A DX MODEL AT THE DEALERSHIP, THE ALTERNATOR CAN OVERCHARGE AND FRY THE ECM/PCM.
IF THE ALTERNATOR BOLTS ARE LOOSE, TIGHTEN THEM AND TRY RESTARTING THE ENGINE. IF IT STILL WONÂ’T START, THEN CHECK THE ECM/PCM CONNECTOR FOR BATTERY VOLTAGE AND GROUND. IF YOUR READINGS ARE GOOD, THEN REPLACE THE ECM/PCM."
