OPDS Unit Initialization

When a seat-back cover/pad and/or OPDS unit is replaced, initialize the OPDS by doing this procedure.
NOTE: A new (uninitialized) OPDS unit installed with a faulty OPDS sensor can cause DTC 85-71 or 85-78.
  1. 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.
  1. Make sure the ignition switch is in LOCK (0).
  1. Connect the HDS to the data link connector (DLC) (A).
  1. Turn the ignition switch to ON (II).
  1. Make sure the HDS communicates with the vehicle and the SRS unit. If it does not communicate, troubleshoot the DLC circuit.
  1. From the HDS Main Menu, select SRS, then SRS, then Calibration. In the Calibration Menu, select OPDS UNIT INITIALIZATION. Follow the screen prompts to initialize the OPDS unit.
  1. Turn the ignition switch to LOCK (0).
  1. Disconnect the HDS from the DLC.
    NOTE: If the OPDS unit fails to initialize after several attempts, replace the OPDS sensor/seat-back and retry. If the OPDS unit continues to fail to initialize, replace the OPDS unit.
