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.

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.

A self-diagnostic circuit is built into the SRS unit; when the ignition switch is turned to ON (II), the SRS indicator comes
on and goes off after about 6 seconds if the system is operating normally.
If the indicator does not come on, or does not go off after 6 seconds, or comes on while driving, it indicates an
abnormality in the system. The system must be inspected and repaired as soon as possible.
For better serviceability, the SRS unit memory stores a DTCs related to the cause of the malfunction, and the unit is
connected to the data link connector (DLC). This information can be read with the HDS when it is connected to the DLC
(see page 24-22).
NOTE: Before you disconnect the negative cable from battery for troubleshooting, review Battery Terminal
Disconnection and Reconnection (see page 22-68).

NOTE: Before doing this troubleshooting procedure,
review SRS Precautions and Procedures (see page
24-13), General Troubleshooting Information (see page
24-22), and Battery Terminal Disconnection and
Reconnection (see page 22-68).
1. Clear the DTC memory (see page 24-23).
2. Turn the ignition switch to ON (II), and check that the SRS indicator comes on for about 6 seconds
and then goes off.
Go to step 3.
Intermittent failure, system is OK at this time.
Go to Troubleshooting Intermittent Failures
(see page 24-24). If another DTC is indicated,
troubleshoot the DTC. 3. Turn the ignition switch to LOCK (0). Disconnect the
negative cable from the battery, then wait at least 3
minutes.
4. Disconnect the driver’s airbag 4P connector (A) from the cable reel.
5. Connect the SRS inflator simulator (2 connectors) and simulator lead J to the cable reel.
Does the SRS indicator stay on, and is DT C 11-1xor 11-4x i nd i cat ed ?
