Initializing Occupant Position Detection System (OPDS) Unit

WARNING: This page is about a different car, the 2002 Acura 3.2CL. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Avoid using jumper wire in place of SCS short connector. Jumper wire may be difficult to connect and disconnect quickly enough.

Turn ignition off. Connect Honda PGM Tester to 16-pin data link connector and follow tester prompts in "SCS" menu. See Figure. Connect SCS Service Connector (07PAZ-0010100) to Memory Erase Signal (MES) connector. See Figure.
Turn ignition on. SRS indicator light will come on for about 6 seconds then go off.
Disconnect SCS service connector from MES connector within 4 seconds after SRS indicator light goes off. SRS indicator light will come on again.
Reconnect SCS service connector to MES connector within 4 seconds after SRS indicator light comes on. SRS indicator light will go off.
Disconnect SCS service connector from MES connector within 4 seconds. SRS indicator light will indicate that OPDS unit is initialized by blinking 2 times. If light doesn"t blink and stays on, repeat procedure. If light blinks 2 times and stays on, read DTC and proceed with troubleshooting. Turn ignition off, and wait 10 seconds.
