Honda Civic. Manual — part 27

ODS UNIT INITIALIZATION

When a seat-back cover, seat-back cushion, and/or ODS unit is replaced, initialize
the ODS by following the procedure.

1. Clear the DTC memory (see CLEAR THE DTC MEMORY WITH THE

HDS).

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 OFF and the MES connector is not shorted.
4. Connect the HDS to the data link connector (DLC) (A).

5. Turn the ignition switch 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 DLC CIRCUIT
TROUBLESHOOTING ).

7. From the HDS Main Menu, select SRS, then SRS, then Adjustments. In the

Adjustment Menu, select ODS INIT. Follow the screen prompts to initialize
the ODS unit.

NOTE:

A new (uninitialized) ODS unit installed with a faulty OPDS
sensor can cause DTC 85-71.

8. Turn the ignition switch OFF.
9. Disconnect the HDS from the DLC.

ODS UNIT CALIBRATION

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 closed.

Do all calibration 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 until 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

recliner to the forwardmost position. Do not move the seat from these
positions.

2. Make sure the ignition switch is OFF.
3. Connect the HDS to the data link connector (DLC) (A).
4. Turn the ignition switch ON (II).

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 ODS UNIT REPLACEMENT).
