JN7 – Safety Recall: SRS Unit – 2003 Acura MDX

NHTSA Campaign Number: 15V045
Manufacturer Honda (American Honda Motor Co.)
Components AIR BAGS
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.

BACKGROUND

Electrical noise (interference) generated by the vehicle may inadvertently cause some or all of the vehicle’s airbags to deploy. Many vehicles had an electrical noise suppressor installed under S/B 13-038, Safety Recall: Electrical Noise May Cause Inadvertent Front Airbag Deployment. In rare cases, even with the noise suppressor installed, some front airbags inadvertently deployed.

NOTE: If the VIN status inquiry indicates that the vehicle is subject to any open safety recalls, including an airbag inflator campaign/recall, make sure to also complete those recall repairs before returning the vehicle to the client. If you are unable to complete any open recall, advise the client of the recall status and when the recall may be completed.

 

CLIENT NOTIFICATION

Owners of affected vehicles will be sent a notification of this campaign.

Do an iN VIN status inquiry to make sure the vehicle is shown as eligible.

Some vehicles affected by this campaign may be in your new or used vehicle inventory. These vehicles must be repaired before they are sold.

Should your dealership sell an unrepaired vehicle that subsequently causes injury or damage because of the recalled item, the dealership will be solely responsible to the damaged party, and will be required to defend and indemnify American Honda for any resulting claims. To see if a vehicle in inventory is affected by this recall, do a VIN status inquiry before selling it.

 

CORRECTIVE ACTION

Inspect the vehicle and based on your results, do one of the following:

  • Do nothing, the vehicle is up to date.
  • Replace the SRS unit.
  • Remove the noise suppressor and replace the SRS unit.

NOTE: When you install a new SRS unit, do not initialize the OPDS unit.

  2. Reinstall the center console side trim.
  3. Reconnect the negative battery cable.

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

 

  1. 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).
  2. 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.

OPDS Sensors

 

  • 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).

OPDS Sensors

 

  1. Enter the anti-theft codes for the audio and navigation system (if applicable), then enter the client’s audio unit presets.
  2. 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.
