OPDS Sensor Initialization

WARNING: This page is about a different car, the 2013 Acura MDX, 2012 Acura MDX, 2011 Acura MDX, and 2010 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.

When you replace a seat-back cover/pad, and/or ODS unit initialize the OPDS sensor with the HDS.

NOTE:

A new (uninitialized) ODS unit installed with a faulty OPDS sensor can cause DTC 85-71 and DTC 85-78.
Before initializing the ODS unit, make sure the battery is fully charged.
Make sure all components of the front passenger's seat are correctly installed.
Make sure nothing is the front passenger's seat.
Make sure there is nothing in the front passenger's seat-back pocket.
Keep the A/C and the heater off.

Clear the DTCs with the HDS (see HOW TO CLEAR DTCS ).
Set the seat-back in a normal position.
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 INITIALIZATION. In the INITIALIZATION Menu, select ODS Initialization. Follow the prompts until the OPDS sensor initialization has been completed.
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 ).
