SRS Unit 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. SRS Unit - Update

NOTE:
* Make sure the HDS/HIM or the MVCI unit has the latest software version.
* If the SRS unit does not display in SYSTEM SELECTION screen of MVCI, it means cannot update the SRS unit. Replace the SRS unit as needed.
* Before you update the SRS unit, make sure the battery in the vehicle is fully charged.
* Never turn the ignition switch to LOCK (0) or ACCESSORY (I) during the update. If there is a problem with the update, leave the ignition switch in ON (II).
* To prevent SRS unit damage, do not operate anything electrical (headlights, audio system, brakes, A/C, power windows, moonroof (if equipped), 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 Honda interface module (HIM) because the HIM's red (#3) light came on or was flashing during the update, leave the ignition switch in ON (II) when you disconnect the HIM 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:
* Leave the ignition switch in ON (II).
* Connect a jumper battery (do not connect a battery charger).
* Shut down the updating tools.
* Disconnect the updating tool from the DLC.
* Reboot the updating tool.
* Reconnect the updating tool to the DLC, and try the update procedure again.

3. Turn the ignition switch to LOCK (0).
