OPDS Sensor Initialization: Notes

When a seat-back cover, a seat-back cushion/pad, and/or the ODS unit is replaced, do this procedure to initialize the OPDS sensor with the HDS unit.

NOTE:

A new (uninitialized) ODS unit installed with a faulty OPDS sensor (DTCs 86-1x or 86-2x) can cause DTC 85-71 and DTC 85-78. If the SRS system has a hard DTC 86-1x or 86-2x, troubleshoot the DTCs completely before replacing the ODS unit.
Before initializing the ODS unit, make sure the 12 volt battery is fully charged.

Clear the DTC memory (see HOW TO CLEAR DTCS ).
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.
Make sure the ignition switch is in LOCK (0).
Connect the HDS to the data link connector (DLC) (A).

Turn the ignition switch to ON (II).
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 ).
From the HDS Main Menu, select SRS, then SRS, then Calibration. In the Calibration Menu, select ODS Unit Initialization. Follow the screen prompts to initialize the ODS unit.
Turn the ignition switch to LOCK (0), then wait for 10 seconds.
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 ODS UNIT REPLACEMENT ).
