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 13-088, 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 customer. If you are unable to complete any open recall, advise the customer of the recall status and when the recall may be completed.

CUSTOMER 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 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 with the HDS. There is a new method to complete the SRS unit installation.

INSPECTION PROCEDURE

Make sure you follow the inspection steps 1-3 to make sure the SRS is functioning properly before doing a repair.

Turn the ignition ON and check if the SRS indicator comes on for about 6 seconds, then goes out.
- If the indicator comes on, then goes out after about 6 seconds, go to step 2.
- If the indicator does not come on, or if it stays on, connect the HDS and write the DTCs on the RO.
  - Contact the customer and inform them that there is a problem with the SRS system and explain that replacing the SRS unit may not fix the problems causing the indicator light to illuminate as the SRS unit replacement was only intended to address the specific problem that led to the recall.
  - If the customer declines the customer pay repairs, make sure you write down the description of the problem and any DTCs on the RO. Also state that the SRS system is not operating properly and may pose a risk to the front occupants in the event of a collision; either because the airbags did not deploy, or the airbags deploy in a manner that does not account for all factors involved in the collision.
  - After the SRS unit is replaced, additional customer pay repairs will likely be needed to return the SRS system to proper operation.

Turn the ignition to OFF and wait for 30 seconds. Turn the ignition to ON and check if the SIDE AIRBAG OFF indicator comes on for about 6 seconds, then goes out.

NOTE: Do not confuse the SIDE AIRBAG OFF indicator and the PASSENGER AIRBAG OFF indicator.

If the indicator comes on, then turns off after about 6 seconds, go to step 3.
If the indicator does not come on at all, or comes on and stays on, connect the HDS and write the DTCs on the RO.
- Have the service advisor contact the customer and inform them that there is a problem with the side airbag and explain that replacing the SRS unit may not fix the problems causing the indicator to illuminate. The SRS unit replacement was only intended to address the specific problem that led to the recall.
- If the customer declines the customer pay repairs, make sure you write down the description of the problem and any DTCs on the RO. Also, state that the SRS system is not operating properly and may pose a risk to the front occupants in the event of a collision; either because the airbags may not deploy, or the airbags may deploy in a manner that does not account for all factors involved in the collision.
- After the SRS unit is replaced, additional customer pay repairs will likely be needed to return the SRS system to proper operation.

Make sure the OPDS is working properly by leaving the ignition turned to ON, then grabbing and holding the passenger seat back outside bolster with both hands for about 30 seconds. The SIDE AIRBAG OFF indicator should come on.
- If the SIDE AIRBAG OFF indicator comes on, go to step 4.
- If the indicator does not come on, connect the HDS and write any SRS DTCs on the RO.
  - Have the service advisor contact the customer and inform them that there is a problem with the OPDS and explain that replacing the SRS unit may not fix the problems. The SRS unit replacement was only intended to address the specific problem that led to the recall.
  - If the customer declines the customer pay repairs, make sure you write down the description of the problem and any DTCs on the RO. Also state that the SRS system is not operating properly and may pose a risk to the front occupants in the event of a collision; either because the airbags may not deploy, or the airbags may deploy in a manner that does not account for all factors involved in the collision.
  - After the SRS unit is replaced, additional customer pay repairs will likely be needed to return the SRS system to proper operation.

Make sure you have the anti-theft codes for the audio and navigation system (if applicable) and write down the frequencies for the audio unit presets.
Disconnect the negative battery cable and wait at least 3 minutes before beginning work.
Remove the center lower trim.

Remove the driver’s and front passenger’s lower heater covers.

Inspect the subharness and note its arrangement:
- The original subharness is installed in the vehicle.
- There is an updated subharness connected to the noise suppressor.
- There is an updated subharness that has been taped up as shown and the noise suppressor has been removed.

Write down the SRS unit P/N on the RO.

Check the SRS unit P/N and arrangement of the subharness against the table below and follow the correct repair action.

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

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

Replace the subharness clip.
Connect the subharness to the new SRS unit (P/N 77960-S0X-407) and connect the clip.
Apply a piece of 80 mm x 80 mm cushion tape over the noise suppressor connector as shown.

Reinstall the new SRS unit and existing SRS subharness into the vehicle with three new Torx bolts and torque them to 8 N·m (7.2 lb-ft).

Reinstall the ground wire with a new Torx bolt and torque it to 8 N·m (7.2 lb-ft).
Reconnect the connectors and the clip.

Clip the noise suppressor subharness to the top of the connectors.
Fold the subharness over and secure it with the wire tie as shown.

NOTE: Make sure the noise suppressor subharness does not block the driver’s heater lower cover connection point.

Reinstall the driver’s and front passenger’s lower heater covers, the center lower pocket, and the center console 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 20.
- If the SRS indicator remains on and the SIDE AIRBAG OFF indicator is flashing, the passenger seat back material around the OPDS may be causing an issue. Do the following for about 1 minute and then repeat step 18-19.
  - If the vehicle has a fabric seat cover, smooth out the fabric across the seat so that it doesn’t bunch up or wrinkle.

If the vehicle has a leather seat, massage the leather to make sure there are no tight areas where the leather is stretched across the seat.

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 steps18-19. 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 customer’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.
