ODS Unit Initialization
ODS Unit Initialization
NOTE:
- After SRS unit or 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
When you replace a seat-back cover/pad, SRS unit, and/or ODS unit initialize the OPDS sensor with the HDS.
NOTE:
- 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.
- Before initializing the ODS unit, make sure the battery is fully charged.
- Before initializing the ODS unit, clear the DTCs.
- Make sure nothing is on the front passenger's seat, including after market seat covers or mats.
- Make sure there is nothing in the front passenger's seat-back pocket.
- Keep the A/C and the heater off.
1. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
2. Set the seat-back in a normal position.
3. Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.
4. Connect the HDS to the data link connector (DLC) (A).
5. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
6. Make sure the HDS communicates with the vehicle and the SRS unit. If it does not communicate, go to the DLC circuit troubleshooting 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), or press the engine start/stop button to select the OFF mode, then wait for 10 seconds.
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 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 frame, 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.
- Before initializing the ODS unit, clear the DTCs.
- Make sure all components of the front passenger's seat are correctly installed.
- Make sure nothing is on the front passenger's seat, including after market seat covers or mats.
- 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 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. Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.
3. Connect the HDS to the data link connector (DLC) (A).
4. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
5. Make sure the HDS communicates with the vehicle and the SRS unit. If it does not communicate, go to the DLC circuit troubleshooting 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), or press the engine start/stop button to select the OFF mode.
9. Disconnect the HDS from the DLC.
