6. Exit the HDS diagnostic system, then select the update mode, and follow the screen prompts to update the ECM/PCM.
7. If the software in the ECM/PCM is the latest, disconnect the HDS/HIM/GNA600 from the DLC, and go back to the procedure that you were
doing. If the software in the ECM/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 ECM/PCM update system requires you to cool the ECM/PCM, follow the instructions on screen. If you run into 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 ECM/PCM:
-
Leave the ignition switch in ON (II) or vehicle in the ON mode.
-
Connect a jumper battery (do not connect a battery charger).
-
Shut down the HDS.
-
Disconnect the HDS from the DLC.
-
Reboot the HDS.
-
Reconnect the HDS to the DLC, and try the update procedure again.
