Good
- Disconnect B-CAN communication units one by one and monitor DTC to find the cause.
- If problem still occurs, replace control unit that causing the fault and then go to "VERIFICATION OF REPAIR " procedure.
No Good
- Check for open, short to battery/ground in B-CAN line.
- Repair as necessary, go to "VERIFICATION OF REPAIR " procedure.
