How to check for DTCs with 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.
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 to ON (II).
  1. Make sure the HDS communicates with vehicle.
    NOTE: If the HDS does not communicate with the vehicle, troubleshoot the DLC circuit.
  1. Select the BODY ELECTRICAL, then select the desired TEST MODE menu, and check the DTCs. If the DTCs do not pertain to the select menu, select the All DTC Check icon to view all Body 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 the DTC B1000 is stored, troubleshoot the DTC B1000 first.
