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

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

NOTE: Check the front passenger's weight sensor output after this action:

- After a vehicle collision

Pre-Operation Check Set-Up With the HDS

- Make sure all the components of the front passenger's seat are correctly installed.
- 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 output check is completed.
- 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 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 front passenger's seat during the operation check.
- Do not expose the front passenger's seat to sudden temperature changes.
- Make sure all aftermarket devices such as amplifiers, fluorescent light, air purifiers, CB or HAM radios, etc. are turned off.

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

2. Turn the ignition switch to 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, go to the DLC circuit troubleshooting:

- R18A1 engine Testing and Inspection
- K20Z3 engine Testing and Inspection

6. 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.

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

8. Disconnect the HDS from the DLC.

Pre-Operation Check Without the HDS

NOTE:

- Always check the front passenger's seat weight sensor output after replacing any of the front passenger's seat components, except the ODS unit, and after a vehicle collision.
- Make sure the SCS line is not shorted by the HDS.

1. Adjust the front passenger's seat-back to a normal upright position, and remove anything that is on or near the seat.

2. Turn the ignition switch to ON (II), and wait for the passenger's airbag cutoff indicator to go off.

3. Apply the specified weight to the front passenger's seat.

4. Apply the specified weight to the front passenger's seat:

- 4-door; 58 lbs (26.5 kg)
- 2-door; 64 lbs (29 kg)

5. Top headrest twice firmly.

6. Add another 15-20 lbs (7-9 kg) of weight to the front passenger's seat.

7. Top headrest twice firmly.

8. Watch the passenger's airbag cutoff indicator. The indicator should go off.

- If the indicator goes off, the front passenger's weight sensors are OK.
- If the indicator does not goes off, check for SRS DTCs and, troubleshoot them, then repeat steps 1 thru 6.
