  • Fault(s) stored in Engine Control Module
  • Engine Control Module recently flashed or re-mapped

Possible Solutions

  • Check CAN-Databus Wiring/Connectors from/to Engine Control Module
  • Check Measuring Value Blocks (MVB)
    • Usually Measuring Value Blocks (MVB) 125+ show the current Communication Status

Special Notes

  • When found in the (1K) chassis with 2.5L gas engine using a MAF (G70) sensor, check the T121/62 (Red/Black) traced power wire to the ECM. If power is missing or a voltage drop is present that wire may be damaged anywhere between 6" and 18" from the connector itself. This will result in no communication in addition to a no-start.
