Component Tests and General Diagnostics

ODS Unit Operation Check

Check the ODS operation after any of these actions:

- Replacement of front passenger's seat component(s) (except ODS unit and/or weight sensors)
- After a vehicle collision
- SRS unit replacement

Pre-Operation Check Set-up

- Make sure all the components of the front passenger's seat are correctly installed.
- Before doing the ODS unit operation check, make sure the battery is fully charged.
- Position the front passenger's seat all the way rearward. Adjust the seat-back all the way forward. Do not move the seat from this position until the operation check is completed.
- 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.
- Turn the heater and the A/C off.
- Do not touch the passenger's seat during the operation check.
- Do not expose the front passenger's seat to sudden temperature changes.
- Make sure all after market devices such as amplifiers, fluorescent light, air purifiers, CB or HAM radios, etc. are turned off.

After Replacing Front Passenger's Seat Component(s)

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

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, accelerate to 22 mph (36 km/h), then stop on level ground.

6. From the HDS Main Menu, select SRS, then Inspection. In the Inspection Menu, select AFTER REPLACING FRONT PASSENGER'S SEAT COMPONENT(S). Follow the prompts until the ODS unit operation check has been completed.

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

8. Disconnect the HDS from the DLC.

Front Passenger's Weight Sensor Output Check After a Vehicle Collision

1. Position the front passenger's seat to the rear most position, and adjust the seat-back to the forward most position. Do not move the seat from this position until the output check is completed.

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

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 Inspection. In the Inspection Menu, select AFTER A VEHICLE COLLISION. Follow the prompts until the front passenger's weight sensor output check has been completed.

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

9. Disconnect the HDS from the DLC.
