Initializing Occupant Position Detection System (OPDS) Unit

WARNING: This page is about a different car, the 2000 Honda Accord. 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.
  1. 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 .
  2. Turn ignition on. SRS indicator light will come on for about 6 seconds then go off.
  3. Disconnect SCS service connector from MES connector within 4 seconds after SRS indicator light goes off. SRS indicator light will come on again.
  4. Reconnect SCS service connector to MES connector within 4 seconds after SRS indicator light comes on. SRS indicator light will go off.
  5. 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.

NOTE: SRS units from 2 manufacturers (NEC and Siemens) are used in Accord. NEC made SRS units are installed in vehicles without side-impact air bag systems. Siemens made SRS units are installed in vehicles with side-impact systems. Ensure correct SRS unit is installed. See SRS UNIT IDENTIFICATION  table.
