Signal Circuit Inspection

Check Open In Harness
1. IG "OFF" and disconnect ECM (PCM) and FPCM connector.
2. Check resistance between CAN-HIGH terminal of ECM (PCM) harness Connector and CAN-HIGH terminal of FPCM harness connector.
3. Check resistance between CAN-LOW terminal of ECM (PCM) harness Connector and CAN-LOW terminal of FPCM harness connector.
  Specification: Below 1.0Ω
4. Is the measured resistance within specification?
  YES
  - Go to "VERIFICATION OF VEHICLE REPAIR ".
  NO
  - Repair open in CAN BUS line. Go to "VERIFICATION OF VEHICLE REPAIR ".
