ODS Unit Initialization

NOTE:

- After ODS unit is replaced, do this procedure to initialize the ODS unit.

- ODS unit initialization will initialize both OPDS sensor and seat weight sensor.

OPDS Sensor Initialization

After a seat-back cover, seat-back cushion, and/or ODS unit is replaced, do this procedure to initialize the OPDS sensor with the HDS unit.

NOTE:

- A new (uninitialized) ODS unit installed with a faulty OPDS sensor can cause DTC 85-71 and DTC 85-78.

- Before initializing the ODS unit, make sure the battery is fully charged.

1. Clear the DTC memory. Reading and Clearing Diagnostic Trouble Codes

2. Make sure the front passenger's seat is dry. Set the seat-back in a normal position, and make sure there is nothing on the seat.

3. Make sure the ignition switch is in LOCK (0) and the MES connector is not shorted.

4. Connect the HDS to the data link connector (DLC) (A).

5. Turn the ignition switch to ON (II).

6. Make sure the HDS communicates with the vehicle and the SRS unit. If it does not communicate, troubleshoot the DLC circuit. Testing and Inspection

7. From the HDS Main Menu, select SRS, then SRS, then Calibration. In the Calibration Menu, select ODS UNIT INITIALIZATION. Follow the screen prompts to initialize the ODS unit.

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

9. Disconnect the HDS from the DLC.
NOTE: If the ODS unit fails to initialize after several attempts, replace the OPDS sensor/seat-back cover/pad Front Seat-Back Cover Replacement and retry. If the ODS unit continues to fail to initialize, replace the ODS unit. ODS Unit Replacement






Front Passenger's Weight Sensor Initialization

When you replace the SRS unit, the front passenger's seat assembly, or the ODS unit, calibrate the seat weight sensor with the HDS unit.

While calibrating the ODS unit, observe these precautions:

- Make sure all components of the front passenger's seat are correctly installed.

- Make sure nothing is on or under the front passenger's seat.

- Make sure there is nothing in the front passenger's seat-back pocket.

- Keep the windows and the moonroof closed.

- Do all calibration procedures, except test-driving, in the service bay.

- Make sure the vehicle is on level ground.

- Keep the A/C and the heater off.

- Do not touch the front passenger's seat during calibration, until you are prompted to or when you have completed the calibration.

- Do not expose the front passenger's seat to sudden temperature changes.

1. Position the front passenger's seat to the rearmost position, adjust the seat height to the lowest position, and adjust the recliner to the forwardmost position. Do not move the seat form this position.

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

3. Turn the ignition switch to ON (II).

4. Make sure the HDS communicates with the vehicle and the SRS unit. If it does not communicate, troubleshoot the DLC circuit. Testing and Inspection

5. Drive the vehicle, and accelerate to 20 mph (36 km/h), then stop on level ground.

6. From the Main Menu, select SRS, then SRS, then Calibration, then select SWS INITIALIZATION, and follow the prompts until the calibration is complete.
