How to Troubleshoot the SRS - Initializing the OPDS Unit/DTC Troubleshooting: 85-71, 85-78
Initializing the OPDS (Occupant Position Detection System) Unit
When a seat-back cover, seat-back cushion, and/or OPDS unit is replaced, initialize the OPDS by following the procedure.
NOTE: A new (uninitialized) OPDS unit installed with a faulty OPDS sensor can cause DTC 85-71.
|1.||Erase the DTC memory (see ‘‘Erasing the DTC Memory'').|
|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 DLC (A).|
|5.||Turn the ignition switch ON (II).|
|6.||From the HDS Main Menu, select SRS, then Misc Test, then adjustments. In the Adjustment Menu, select OPDS INIT. Follow the screen prompts to initialize the OPDS.|
|7.||Turn the ignition switch OFF.|
|8.||Disconnect the HDS from the DLC.|
NOTE: If the OPDS system fails to initialize after several attempts, replace the OPDS sensor and retry. If the OPDS system continues to fail to initialize, replace the OPDS unit.
