Initializing Occupant Position Detection System (OPDS) Unit

NOTE: Do not use a jumper wire in place of SCS short connector. Jumper wire may be difficult to connect and disconnect quickly enough.

Place right seat back in normal position. Ensure nothing is sitting on right front seat cushion and right front seat is free of moisture. Turn ignition switch to OFF position. Connect Honda Diagnostic System to 16-pin data link connector and follow tester prompts in SCS menu to ground SCS line. See Figure . Connect SCS Service Connector (07PAZ-0010100) to Memory Erase Signal (MES) connector. See Figure .
Turn ignition switch to ON position. AIR BAG warning light will come on for about 6 seconds then go off.
Disconnect SCS service connector from MES connector within 4 seconds after AIR BAG warning light goes off. AIR BAG warning light will come on again.
Reconnect SCS service connector to MES connector within 4 seconds after AIR BAG warning light comes on. AIR BAG warning light will go off.
Disconnect SCS service connector from MES connector within 4 seconds. AIR BAG warning 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 Diagnostic Trouble Code (DTC) and proceed with troubleshooting.
Turn ignition switch to OFF position, and wait 10 seconds. Disconnect Honda Diagnostic System. Turn ignition switch to ON position and monitor AIR BAG warning light. If AIR BAG warning light comes on for about 6 seconds and goes off, and AIR BAG warning light does not come back on for 30 seconds, initialization of OPDS unit is complete.

⁽¹⁾	Before replacing SRS unit, ensure battery is fully charged. Clear DTCs. Turn ignition switch to ON position. If AIR BAG warning light stays ON, replace SRS unit. If AIR BAG warning light does not stay on, check for intermittent problem. See TROUBLESHOOTING INTERMITTENT FAILURES .

⁽²⁾	If intermittent, code could result from an internal failure of SRS unit or faulty indicator light circuit.

⁽³⁾	If intermittent, code could result from an internal failure of power supply (VB line). See TROUBLESHOOTING INTERMITTENT FAILURES .

⁽⁴⁾	SRS unit must be replaced if any air bags and/or pretensioners have deployed.

⁽⁵⁾	Clear DTCs. Turn ignition switch to ON position. If AIR BAG warning light stays ON, replace appropriate impact sensor. If AIR BAG warning light does not stay on, check for intermittent problem. See TROUBLESHOOTING INTERMITTENT FAILURES .
