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 front passenger's weight sensor.

OPDS Sensor Initialization

When you replace a seat-back cover/pad, and/or ODS unit initialize the OPDS sensor with the HDS.

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.
- Make sure all components of the front passenger's seat are correctly installed.
- Make sure nothing is on the front passenger's seat.
- Make sure there is nothing in the front passenger's seat-back pocket.
- Keep the A/C and the heater off.

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

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

3. Make sure the ignition switch is in LOCK (0).

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 INITIALIZATION. In the INITIALIZATION Menu, select ODS Initialization. Follow the prompts until the OPDS sensor initialization has been completed.

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 seat-back cover/pad with equipped OPDS sensor Front Seat-back Cover/Pad 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 weight sensor, the front passenger's seat assembly, 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.
- Make sure there is nothing in the front passenger's seat-back pocket.
- Keep the windows and the moonroof closed.
- Do all initialization 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 initialization, until you are prompted to or when you have completed the initialization.
- 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. Make sure the ignition switch is in LOCK (0).

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






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

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

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

7. 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.

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

9. Disconnect the HDS from the DLC.
