Initializing Occupant Position Detection System (OPDS) Unit
WARNING: This page is about a different car, the 2000 Acura 3.5RL. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
DO NOT use a jumper wire in place of SCS short connector. Jumper wire may be difficult to connect and disconnect quickly enough.
- Turn ignition off. Connect SCS Short Connector (07PAZ-0010100) to service check connector. See Figure. Remove SCS short connector and connect 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.
