| A18070 | 2018-09-04. Service bulletin. ENGINE AND ENGINE COOLING. Service bulletin - Emission certification labels that were replaced on a small number of vehicles may have been replaced with a label listing incorrect information. The affected emission labels are replacement service parts, and were not installed at the factory; they were installed during postmanufacturing repairs that required replacement of the underlying part. This will cause the vehicle to be non-compliant with emissions regulations. |

"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 WON’T START, THEN CHECK THE ECM/PCM CONNECTOR FOR BATTERY VOLTAGE AND GROUND. IF YOUR READINGS ARE GOOD, THEN REPLACE THE ECM/PCM." |
