CAN Register And Communication Line Inspection 1
- IG Key "OFF".
- Connect ECM/PCM, ESP, EPS, BSD connector.
- Measure resistance between terminal 3 and 11 of diagnostic connector.
Specification: About 60 Ω
- Is the measured resistance within specification?
YES
- Check BSD (RH) 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
- If the measured value is lower than 10Ω, repair or replace CAN High and 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 CAN High/CAN Low circuit. And then, go to "VERIFICATION OF VEHICLE REPAIR " procedure.
