Signal Circuit Inspection

Check open in harness
1. IG "OFF" and disconnect PCM and IDB connector.
2. Check resistance between CAN-HIGH terminal of PCM harness Connector and CAN-HIGH terminal of IDB harness connector.
3. Check resistance between CAN-LOW terminal of PCM harness Connector and CAN-LOW terminal of IDB harness connector.

Specification :Below 1.0Ohms




4. Is the measured resistance within specification ?
