Initializing the OPDS (Occupant Position Detection System) Unit

Manual Mode
When a seat-back cover, seat-back cushion, OPDS unit, and/or the SRS unit is replaced, initialize the OPDS by following the procedure, only when the HDS does not have the latest software.
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 seal.
2. Make sure the ignition switch is OFF.




3. Connect the HDS to the DLC (A) and turn on the HDS.
4. All the screen prompts, enter the VIN and the odometer reading.
5. From the System Selection Menu screen, select SCS and follow the screen prompts.




6. Plug the SCS service connector (A) into the yellow 2P memory erase signal (MES) connector (B). Do not use a jumper wire.
7. Turn the ignition switch ON (II).
8. Watch the SRS indicator. It will come on for about 6 seconds and then go off. Unplug the SCS service connector from the 2P MES connector within 4 seconds after the indicator goes off.
9. When the SRS indicator comes on again, plug the SCS service connector into the 2P MES connector within 4 seconds after the indicator comes on.
10. When the SRS indicator goes off, unplug the SCS from the 2P MES connector within 4 seconds.
11. Watch the SRS indicator:
- If the indicator blinks twice and then goes off, the OPDS is initialized. Turn the ignition switch off, and disconnect the HDS.
- If the indicator blinks twice and then stays on, the OPDS is initialized, but the SRS DTC's need to be cleared.
- If the indicator stays on without first blinking, the OPDS is not initialized. Repeat steps 3 thru 10.
