PCM Update

*: Any one of the above updating tools can be used.

Procedure

1. HDS DLC - Connection

1. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.

2. Turn the ignition switch to ON (II).

3. Make sure the HDS communicates with the vehicle. If it does not communicate, go to the DLC circuit troubleshooting.

2. PCM - Update

1. Connect an updating tool to the data link connector.

2. Follow the screen prompts to update the PCM.

3. If the software in the PCM is the latest, disconnect the updating tool from the DLC, then go back to the procedure that you were doing. If the software in the PCM is not the latest, follow the instructions on the screen. If prompted to choose the PGM-FI system or the A/T system, make sure you update both.

NOTE: If the PCM update system requires you to cool the PCM, follow the instructions on screen. If you have a problem during the update procedure (programming takes over 15 minutes, status bar goes over 100 %, D or immobilizer indicator flashes, HDS tablet freezes, etc.), follow these steps to minimize the chance of damaging the PCM.
* Leave the ignition switch in ON (II).
* Connect a jumper battery (do not connect a battery charger).
* Shut down the updating tool.
* Disconnect the updating tool from the DLC.
* Reboot the updating tool.
* Reconnect the updating tool to the DLC, and try the update procedure again.

4. After updating, disconnect the updating tool from the DLC.

NOTE: If the radiator fan comes on, do not include its running time in the 5 minutes.
