ODS Unit Initialization

Procedure

NOTE:
* After SRS unit or ODS unit is replaced, do this procedure to initialize the ODS unit.
* ODS unit initialization initializes both the OPDS sensor and the front passenger's weight sensor.

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. DTC - Clear

1. Clear the DTC(s) by following the screen prompts on the HDS.

2. Turn the ignition switch to LOCK (0), then wait for 10 seconds.

3. OPDS Sensor Initialization

OPDS Sensor Initialization

When you replace the front passenger's seat-back cover/pad, the SRS unit, and/or the ODS unit, initialize the OPDS sensor with the HDS.

NOTE:
* Before initializing the ODS unit, make sure the battery is fully charged.
* A new (uninitialized) ODS unit installed with a faulty OPDS sensor (DTC 86-1x or 86-2x) can cause DTCs 85-71 and 85-78. If the SRS has a hard DTC 86-1x or 86-2x, troubleshoot the DTCs completely before replacing the ODS unit.
* Make sure all components of the front passenger's seat are correctly installed.
* Make sure nothing is on the front passenger's seat, including aftermarket seat covers or mats.
* Make sure there is nothing in the front passenger's seat-back pocket.
* Dehumidify inside of the vehicle with A/C.

1. Set the seat-back in a normal position.

2. From the HDS Main Menu, select SRS, then INITIALIZATION. In the INITIALIZATION Menu, select ODS Initialization. Follow the prompts until the OPDS sensor initialization has been completed.

3. Turn the ignition switch to LOCK (0), then wait for 10 seconds.

NOTE: If the ODS unit fails to initialize after several attempts, replace the seat-back cover/pad equipped with an OPDS sensor, and retry. If the ODS unit continues to fail to initialize, replace the ODS unit.

4. Front Passenger's Weight Sensor Initialization

Front Passenger's Weight Sensor Initialization

When you replace the SRS unit, the front passenger's weight sensor, the front passenger's seat frame, front passenger's seat rail, or the ODS unit, initialize the front passenger's weight sensor with the HDS.

NOTE:
* Before initializing the front passenger's weight sensor, make sure the battery is fully charged.
* Make sure all components of the front passenger's seat are correctly installed.
* Make sure nothing is on the front passenger's seat, including aftermarket seat covers or mats.
* Make sure there is nothing in the front passenger's seat-back pocket.
* Keep the windows and the moonroof closed.
* Make sure the vehicle is on level ground.
* Dehumidify inside of the vehicle with A/C.
* Do not touch the front passenger's seat during the operation check.
* Do not expose the front passenger's seat to sudden temperature changes.

1. Position the front passenger's seat all the way rearward, and adjust the seat-back to the forward most position. Do not move the seat from this position until the initialization is completed.

2. Drive the vehicle, and accelerate to 22 mph (36 km/h), then stop on level ground.

3. From the HDS Main Menu, select SRS, then INITIALIZATION. In the INITIALIZATION Menu, select SWS Initialization. Follow the prompts until the front passenger's weight sensor initialization has been completed.

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