CAN Register And Communication Line Inspection
WARNING: This page is about a different variant/trim than selected.
- CAN REGISTER AND COMMUNICATION LINE INSPECTION 1
- IG KEY OFF.
- Connect PCM, 4WD ECU, TCM, ABS connector.
- Measure resistance between terminal 3 and 11 of diagnostic connector.
Specification: About 60 Ω
- Is the measured resistance within specification?
YES
- Check 4WD 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.
- Go to next procedure.
NO
- If the measured value is out of specification, repair or replace 120Ω CAN register (Inside of PCM and Cluster) and then, go to "VERIFICATION OF VEHICLE REPAIR " procedure.
- 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.
- Go to next procedure.
- CAN REGISTER AND COMMUNICATION LINE INSPECTION 2
- IG KEY OFF
- Disconnect PCM connector and Cluster connector.
- Measure resistance between terminal CAN Low and CAN High of ECM.
Specification: About 120 Ω
- Is the measured value within specification?
YES
- Go to next procedure.
NO
- If the measured value is out of specification, repair or replace 120Ω CAN register (Inside of PCM and Cluster) and then, go to "VERIFICATION OF VEHICLE REPAIR " procedure.
- 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.
