How to Troubleshoot the B-CAN System
Troubleshoot the B-CAN Circuit Related Problems
Using the HDS (preferred method)
The HDS can check the F-CAN and B-CAN communication status, read and clear the DTCs, display the data list, and perform function test.
NOTE: If the HDS does not communicate with the vehicle, troubleshoot the DLC circuit.
Check for DTCs
  1. Connect the HDS to the data link connector (A) located under the driver's side of the dashboard.
  1. Turn the ignition switch ON (II).
  1. Make sure the HDS communicates with vehicle. If it doesn't, troubleshoot the DLC circuit.
  1. Select the BODY ELECTRICAL, then enter the TEST MODE menu, and check the DTCs.
    NOTE: For specific operations, refer to the HDS user's manual.
  1. If any DTCs are indicated, go to the indicated DTCs troubleshooting.
    NOTE: If a number of DTCs are indicated, always troubleshoots the lowest number of the DTC first.
