ODS Unit Initialization

ODS Unit Initialization

NOTE:

- After ODS unit is replaced, do this procedure to initialize the ODS unit.
- ODS unit initialization will initialize OPDS sensor and front passenger's weight sensor.

OPDS Sensor Initialization

When a seat-back cover, a seat-back cushion/pad, and/or the 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 DTCs with the HDS 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).

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 OPDS 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 OPDS sensor/seat-back 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, front passenger's weight sensors, or the ODS unit, initialize the front passenger's weight sensor with the HDS unit.

While doing the initialization of the ODS unit, observe these precautions:

- Before initialization 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 or under the front passenger's seat.
- Make sure there is nothing in the front passenger's seat-back pocket.
- Keep the windows 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 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. Make sure the ignition switch is in LOCK (0).

2. Position the front passenger's seat all the way rearward position, and adjust the seat-back to the all the way forward. Do not move the seat from this position.

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 20 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.
