Air Bag Control Module: Testing and Inspection

SRS Unit Update

Special Tools Required

- Honda Diagnostic System (HDS) tablet tester
- Honda Interface Module (HIM) and an iN workstation with the latest HDS software version
- HDS pocket tester
- GNA600 and an iN workstation with the latest HDS software version
- MVCI unit with the latest control module (CM) update software installed
Any one of the above updating tools can be used.

NOTE:

- Make sure the HDS/iN workstation or MVCI has latest HDS software version.
- 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 replaced.
- You cannot update an SRS unit with a program it already has. It will only accept a new program.
- If you need to diagnose the 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. Make sure the ignition switch is in LOCK (0).

2. Connect the updating tool to the data link connector (DLC) (A).





3. Turn the ignition switch to ON (II), but do not start the engine.

4. Make sure the updating tool communicates with the vehicle and the SRS unit. If it does not communicate, go to the DLC circuit troubleshooting Testing and Inspection.

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

6. 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 or immobilizer light flashes, updating tool 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 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.

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

8. Disconnect the updating tool from the DLC.
