Good
- Disconnect P-CAN communication units one by one and monitor DTC to find the cause.
- If the DTC is erased, check for proper operation. If the problem is corrected, replace the unit and go to "Verification Of Repair " procedure.
No Good
- Check for open, short to battery or ground in P-CAN line.
- Repair as necessary, go to "Verification Of Repair " procedure.
