Potential Number of Units Affected 374,177

Inadvertent Air Bag Deployment

Inadvertent deployment of the air bags may increase the risk of injury and the possibility of a vehicle crash.

Summary

Honda is recalling certain model year 2003-2004 Honda Odyssey vehicles manufactured February 13, 2002, to August 13, 2004, and 2003 Acura MDX vehicles manufactured February 21, 2002, to September 23, 2003.

Due to electrical noise, a component in the air bag control module may fail, causing the front air bags, side air bags, and/or seatbelt pretensioners to deploy inadvertently while the vehicle is being operated.

Remedy

Honda dealers will replace the supplemental restraint system electronic control unit (SRS ECU). The recall began on February 22, 2016.

Owners may contact Honda customer service at 1-800-999-1009.

Honda’s number for this recall is JN6 (Odyssey), and JN7 (MDX).

Note: This recall supersedes recall 13V-412.

Vehicles that had a noise filter installed as the remedy for that campaign need to have the SRS ECU replaced under this campaign.

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

REPAIR PROCEDURE A

Cut the wire tie and unbolt the suppressor bracket.

On the driver’s side, disconnect the clip, then disconnect the two yellow connectors and the blue connector.

Remove the SRS ground wire Torx (T30) bolt.

Remove the SRS unit by removing the three Torx (T30) mounting bolts.

NOTE: Two of the bolts are accessible from the driver’s side, and one is accessible from the front passenger’s side.

Remove the SRS unit and the subharness from the vehicle.

Remove the subharness clip from the underside of the SRS unit, then disconnect the subharness from the old SRS unit.

Connect the subharness to the new SRS unit P/N 77960-S3V-307.
Remove the bracket from the suppressor because you will reuse the bracket. Do not reuse the noise suppressor.

Apply a piece of 80 mm x 80 mm cushion tape over the noise suppressor connector as shown.
Using a wire tie, secure the old bracket to the harness as shown. In a later step this will hold the harness with the connector pointing down.

Reinstall the new SRS unit and subharness into the vehicle.
- Make sure the SRS unit is squarely against its bracket and install the three new Torx bolts. Torque them to 9.8 N•m (7.2 lb-ft).
- Install the fourth new Torx bolt to secure the ground wire and torque it to 9.8 N•m (7.2 lb-ft).

Reinstall the bracket using the original bolt as shown. Make sure the connector is pointing downward.

Make sure the SRS subharness does not interfere with or rub against the shift cable.

Reconnect the two yellow connectors and the blue connector, then reconnect the clip.
Reinstall the center console side trim.
Reconnect the negative battery cable.

NOTE: Do not initialize the OPDS unit with the HDS.

To ready the vehicle for OPDS initialization, do this:
- Move the front passenger’s seat back to the most upright position.
- Slide the front passenger’s seat all the way back.
- Make sure there is nothing in the front passenger’s seat back pocket.
- Make sure there is nothing under the front passenger’s seat.
- Make sure the vehicle is parked out of direct sunlight.
- Make sure the vehicle’s temperature has stabilized to the shop temperature (do not initialize the vehicle in extreme cold or hot temperatures).
To complete SRS unit initialization, turn the ignition to ON for 1 full minute, turn the ignition off for another minute, then repeat two more times, making sure to wait 1 full minute between turning the ignition key ON or OFF. After cycling the ignition 3 times, turn the ignition to ON and if the SRS indicator comes on for about 6 seconds then goes off, the SRS unit initialization is complete.
- If the OPDS is initialized (the indicator light is off) and it passed all the inspection items (INSPECTION PROCEDURE steps 1-3), go to step 19.
- If the SRS indicator remains on and the SIDE AIRBAG OFF indicator is flashing, the leather passenger seat back material around the OPDS may be causing an issue. Massage the leather to make sure there are no tight areas where the leather is stretched across the seat for about 1 minute and then repeat step 17-18.

If the SRS indicator remains on after the doing the OPDS initialization it is most likely because the interior of the front seat around the OPDS isn’t completely dry. After drying the seat, repeat steps 17-18. To dry the seat, do this:
- Close the vehicle windows and sunroof.
- Start the engine and run the HVAC at its lowest temperature setting and make sure the A/C is on.
- Aim the vents at the OPDS sensor area.
- If you can’t safely run the vehicle to dry the seat, use a shop fan aimed directly at the OPDS sensor.
- Try to initialize the OPDS every 30 minutes. If it doesn’t initialize, continue drying the seat and try again in 30 minutes. Most seats will dry within 1.5 hours.
If the SRS indicator remains on and the SIDE AIRBAG OFF indicator is flashing, use the HDS to initialize the OPDS from the SRS menu.

NOTE: If the SRS indicator is on and the SIDE AIRBAG OFF indicator is flashing, do not initialize the SWS (seat weight sensor).

Enter the anti-theft codes for the audio and navigation system (if applicable), then enter the client’s audio unit presets.
Reset the power window control unit:
- Turn the ignition to OFF, then back to ON.
- Press the driver’s window switch firmly to the second detent to lower the window all the way down.
- When the window reaches the bottom, continue holding the driver’s window switch in the down position for 2 seconds.
- Pull the driver’s window switch up and hold it to the second detent to raise the window without stopping.
- When the window reaches the top, continue holding the driver’s window switch in the up position for 2 seconds.
Vehicles without navigation: Set the clock.
Do the idle learn procedure.
- Make sure all electrical items (A/C, audio unit, defogger, lights, etc.) are off.
- Start the engine and let it warm up to its normal operating temperature (the cooling fans cycle twice).
- Let the engine idle (throttle closed and all electrical items off) for 10 minutes.

NOTE: Do not initialize the OPDS unit.
