■ CAN register and communication line inspection 1
- Ignition "OFF".
- Connect all module connectors in proper locations.
- Measure resistance between terminal 3 and 11 of Data Link Connector (DLC).
Specification: approx. 60 Ω
- Is the measured resistance within specification?
YES
- Check 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 "■ CAN register and communication line inspection 2 " procedure.
NO
- If the measured value is out of specification, repair or replace 120Ω CAN register (Inside of ECM/PCM and CLU) 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.
- Go to "■ CAN register and communication line inspection 2 " procedure.
