CAN Communication Circuit Inspection (BSD ECU ↔ EMS)
- IG Key "OFF".
- Disconnect BSD ECU (RH) connector and EMS connector.
- Measure the resistance between CAN-HIGH terminal of BSD ECU harness connector and CAN-HIGH terminal of ECM/PCM harness connector.
- Measure the resistance between CAN-LOW terminal of BSD ECU harness connector and CAN-LOW terminal of ECM/PCM harness connector.
Specification: below 1Ω
- Is the measured resistance within specification?
YES
- Check BSD ECU connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO
- Check for short in harness.
- Repair as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
