Initializing the OPDS {Occupant Position Detection System} Unit
Special Tool Required
SCS service connector 07PAz-00'1 01 00
When a seat-back cover, seat-back cushion, and/or OPDS unit is replaced, initialize the OPDS by following theprocedure below.
NOTE: Make sure the front passenger's seat is dry. Set the seat-back in the normal position, and make sure there isnothing on the seat.
'1. l\4ake sure the ignition switch is OFF.
2. Connect the Honda PGM Tester (A) to the DLC (16P) (B), andfollowtheTester's prompts jn the ,,SCS,, menu toground the SCS line (see the Honda PGM Tester Operator's ManuaD.
3. Connect the SCS service connector (C) to the MES 2P connector (D). Do not use a iumoer wire.

4. Turn the ignition switch ON {ll).
5. The SRS indicator comes on for about 6 seconds and goes off. Remove the SCS service connector from the MESconnector within 4 seconds after the SRS indicator went off.
6. The SRS indicator comes on again. Reconnect the SCS service connector to the MES connector within 4 secondsafter the SRS indicator comes on.
7. The SRS indicator goes off. Remove the SCS service connector from the MES connector withln 4 seconds.8. Watch the sRS indicator.'lftheindicatorblinkstwotimesandthenstayson,theOPDSisinitialized.buttheDTCSneedtobeerased.Goto

Self-diagnosis System
A self-diagnosis circuit is built into the SRS uniU when the ignition switch is turned ON (ll), the SRS indicator comes onand goes off after about 6 seconds if the SRS is operating normally.
lf the indicator does not come on, or does not go off after 6 seconds. or if il comes on while driving, it indicates anabnormality in the SRS. The SRS must be inspected and repaired as soon as possible.
For better serviceability, the SRS unit memory stores a DTC that relates to the cause of the malfunction, and the unit isconnected to the data link circuit. This information can be read with the Honda PGM Tester when it is connected to thedata link connector (DLc) (see page 23-23).
