Troubleshooting the CAN circuit related problems


Using the PGM Tester or the HDS (Preferred method)


1.Go to B-CAN system diagnosis test mode A.

2.If no DTCs are retrieved, go to Test Mode C or D.

Without the PGM Tester or the HDS
(Should be used if PGM Tester or the HDS is unavailable)


3.Check for communication circuit problems using Mode 1.

4.Check for DTCs while in Mode A.

5.Sort, and then troubleshoot the DTCs in the order below. Refer to the DTC troubleshooting Index for DTC descriptions.

1st. Internal Error DTCs 
2nd. Loss of communication DTCs 
3rd. Signal Error DTCs
