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.
c07PAZ-00r0100
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

Component Replacement/lnspection After Deployment
NOTE: Before doing any SRS repairs. use the PGM
Tester SRS menu method to check for DTCS; refer to the
DTC Troubleshooting Index for the less obvious
deployed parts (seat beit tensioners, front sensors, side
airbag sensors, etc.)
After a collision where the seat belt tensioners
deployed, replace these items:' Seat belt tensioners. Seat belt buckle tensioners. SRS unit. Front impact sensors
After a collision where the front airbag(s) deployed.
replace these items:. SRS unit. Deployed airbag(s). Seat belt tensioners. Seat belt buckle tensioners. Front impact sensors
After a collision where the side airbag{s) deployed,
replace these items:. SRS unit. Deployed side airbag(s). Side impact senso(s)for the side(s) that deployed
During the repair process, inspect these areas:
. lnspect allthe SRS wire harnesses. Replace, don't
repair, any damaged harnesses.. Inspectthecable reelfor heatdamage. lf there is any
damage, replace the cable reel.
Afterthe vehicle is completely repaired, turn the
ignition switch ON (ll). lf the SRS indicator comes on for
about 6 seconds and then goes off, the SRS airbag
system is OK. lf the indicator does not function properly,
use the PGM Tester SRS Menu Method to read the DTC
(see page 23-23). lf this doesn't retrieve any codes, use
the Tester's SCS menu method (see page 23-24). lf you
still cannot retrieve a code, go to SRS Indicator Circuit
Troubleshooting.
