SRS Unit - Update

NOTE:

Make sure the HDS or the MVCI unit has the latest HDS software version.
Before you update the SRS unit, make sure the battery in the vehicle is fully charged, and connect a jumper battery (not a battery charger) to maintain system voltage.
Never press the engine start/stop button during the update. If there is a problem with the update, keep the vehicle in ON mode.
To prevent SRS unit damage, do not operate anything electrical (headlights, audio system, brakes, A/C, power windows, door locks, etc.) during the update.
To ensure the latest program is installed, do an SRS unit update whenever the SRS unit is substituted or replaced.
You cannot update an SRS unit with the program it already has. It will only accept a new program.
If you need to diagnose the MVCI unit because any error message is indicated on the MVCI unit display during the update, keep the vehicle in ON mode when you disconnect the MVCI unit from the data link connector (DLC). This will prevent SRS unit damage.

1. Select the update program, and follow the screen prompts to update the SRS unit.

2. If the software in the SRS unit is the latest, disconnect the updating tool from the DLC, and go back to the procedure that you were doing. If the software in the SRS unit is not the latest, follow the instructions on the screen.

NOTE: If you run into a problem during the update procedure (programming takes over 15 minutes, status bar goes over 100%, D position or immobilizer indicator flashes, HDS tablet freezes, etc.), follow these steps to minimize the chance of damaging the SRS unit:

Keep the vehicle in the ON mode.
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 tools.
Reconnect the updating tool to the DLC, and try the update procedure again.

3. Press the engine start/stop button to select the OFF mode.
