How to Retrieve DTCs

1. With the vehicle in OFF (LOCK) mode, connect the HDS to the data link connector (DLC)

2. Turn the vehicle to the ON mode.

3. Make sure the HDS communicates with the vehicle and the VSA modulator-control unit. If it does not, go to the F-CAN circuit troubleshooting

4. Follow the prompts on the HDS to display the DTC (s) on the screen. After determining the DTC, refer to the DTC troubleshooting. Do the all systems DTC check, and troubleshoot any powertrain DTCs first.

5. Turn the vehicle to the OFF (LOCK) mode.
