Checking Front Passenger’s Weight Sensors
After a Vehicle Collision
24-25
A
10. Shake the related wire harnesses and theconnectors, and look for loose connections, poor
pinfits, and poor grounds.
11. Take a test-drive (quick acceleration, quick braking, and cornering), turn the steering wheel fully left
and right, and hold it there for 5 to 10 seconds. If
the problem recurs, the SRS indicator will come on.
12. If you cannot duplicate the concern, ask the client about the conditions when it occurred, or ask the
client to demonstrate the concern.
13. If you cannot duplicate the intermittent failure, the system is OK at this time. 1. Position the front passenger’s seat to the rearmost
position, adjust the seat-back to the forwardmost
position. Do not move it from this position.
2. Drive the vehicle, accelerate to 20 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 does not communicate,
troubleshoot the DLC circuit (see page 11-204).
7. From the SRS inspection menu, select Seat Weight Sensor, then Misc test, then SEAT OUTPUT CHK
and follow the prompts until the front passenger’s
weight sensor operation check is complete.

ODS Unit Initialization
A
When a seat-back cover, seat-back cushion, and/or ODS
unit is replaced, initialize the ODS by following the
procedure.
NOTE: A new (uninitialized) ODS unit installed with a
faulty OPDS sensor can cause DTC 85-71.
1. Clear the DTC memory (see page 24-23).
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) and the MES connector is not shorted.
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 (see page 11-204).
7. From the HDS Main Menu, select SRS, then SRS, then Calibration. In the Calibration Menu, select
ODS INITIALIZATION. Follow the screen prompts to
initialize the ODS unit.
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 (see page 24-209).

ODS Unit Calibration
A
When you replace the SRS unit, front passenger’s
weight sensors or ODS unit, calibrate the ODS unit.
While calibrating the ODS unit, observe these
precautions: 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 and moonroof closed.
 Do all calibration procedures except, test-driving, in the service bay.
 Make sure the vehicle is on level gr ound.
 Keep the A/C and the heater off.
 Do not touch the front passenger’s seat during calibration, unless you are prompted to or when you
have completed the calibration.
 Do not expose the front passenger’s seat to sudden temperature changes.
1. Position the front passenger’s seat to the rearmost position, and adjust the seat-back to the
forwardmost position. Do not move the seat from
these positions.
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 (see page 11- 204).6. Drive the vehicle, and accelerate to 20 mph
(36 km/h), then stop on level ground.
7. From the Main Menu, select SRS, then Calibration, then Misc Test, then select SWS INITIALIZATION,
and follow the prompts until the calibration is
complete.

 Make sure all the components of the front passenger’s seat are correctly installed.
 Position the front passenger’s seat to the rearmost position.
 Adjust the seat-back to the forwardmost position.
 Do not move the seat from this position.
 Make sure nothing is on or under the front passenger’s seat.

 Turn the heater and the A/C off.
 Do not touch the front passenger’s seat during the calibration, unless you are prompted to or until you
have completed the operation check.
 Do not expose the front passenger’s seat to sudden temperature changes.
 Make sure all aftermarket devices such as amplifiers, fluorescent lights, air purifies, CB or HAM radios, etc.
are turned off. 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 (see page 11-204).

Driver’s Seat Position Sensor Operation Check
A A

Check the driver’s seat position after any of these
actions.
 Driver’s seat position sensor replacement
 Cover plate (front side of driver’s seat slide rail) replacement
1. Make sure the driver’s seat is at its full forward position.
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 (see page 11- 204).
6. From the HDS Main Menu, select SRS, then Prameter Information, then Buckle Switch, Seat
Position Sensor. 7. Using a piece of tape (A), mark the location on the
seat’s outer cover (B) where the front riser cover
meets the seat riser (C). The driver’s seat position
sensor should read NEAR.
8. Move the seat back in small increments (about 0.2 in., 5 mm) until the driver’s seat position sensor
reads NOT NEAR. The seat should be about 25 mm
(1 in.) from the front.
NOTE: It takes a few seconds for the HDS to display changes, so wait about 5 seconds between each
move.
 If the driver’s seat position sensor data does not work as described, check the driver’s seat
positionsensororthecoverplatefordamage,
and replace parts as needed.
9. Turn the ignition switch to LOCK (0), and disconnect the HDS from the DLC.
