H-CAN Register and Communication Line Inspection
WARNING: This page is about a different variant/trim than selected.
■ H-CAN Register and Communication Line Inspection 1
- IG KEY OFF.
- Connect PCM, BMS connector.
- Measure resistance between terminal H-CAN High and H-CAN Low of PCM connector.
Specification : About 60 Ω
- Is the measured resistance within specification?
- Check Each Module 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.
- Go to next procedure.
NO
- If the measured value is out of specification, repair or replace 120Ω CAN register (Inside of PCM and BMS) and then, go to "VERIFICATION OF VEHICLE REPAIR " procedure.
- If the measured value is lower than 10Ω, repair or replace H-CAN High and H-CAN Low are short each other. And then, go to "VERIFICATION OF VEHICLE REPAIR " procedure.
- If the measured value is ∞ Ω, repair or replace the open in H-CAN High/H-CAN Low circuit. And then, go to "VERIFICATION OF VEHICLE REPAIR " procedure.
- Go to next procedure.
