23 : Right Cowl Front Sensor Input Feed/Return Circuit Open

Normal Operation
Battery voltage is provided at air bag diagnostic monitor pin 15 (circuit 611, W/O) at all times. However, voltage at pin 15 can be as high as 19 volts (as provided by the backup power supply) when the ignition switch is in the RUN position and the backup power supply in the air bag diagnostic monitor is charged up. Circuit 612 (P/O) is connected to circuit 611 (W/O) inside the right cowl side panel front air bag sensor and bracket. Therefore, the voltage at pin 23 (circuit 612, P/O) should be the same as the voltage at pin 15 at all times. The air bag diagnostic monitor compares the voltage available at pins 15 and 23. If the voltage at pin 23 is low, the air bag diagnostic monitor will flash out code 23 to indicate an open between these two circuits.

Possible Causes
Low voltage at pin 23 can be caused by:

1. An open circuit in the wiring harness in either circuit 611 (W/O) or 612 (P/O).
2. An open circuit inside the right cowl side panel front air bag sensor and bracket across the W/O and P/O wires.
