Test Notes

Normal Operation
The voltage at Pin C209-16, Circuit 617 (PK/O), is set by the air bag diagnostic monitor to be slightly less than battery voltage. Circuit 617 (PK/O) is connected to Circuit 624 (Y/W) inside the RH air bag sensor. Therefore, the voltage at Pin C208-24, Circuit 624 (Y/W) should be the same as the voltage at Pin C209-16, Circuit 617(PK/O).

The air bag diagnostic monitor periodically pulls the voltage at Pin C209-16, Circuit 617 (PK/O), low to verify the connection to Pin C208-24, Circuit 624 (Y/W). If the voltage at Pin C208-24, Circuit 624 (Y/W), does not pull low as a result of this test, the air bag diagnostic monitor will store in memory the Diagnostic Trouble Code (DTC) B1941 and flash a Lamp Fault Code (LFC) 41 on the air bag indicator. If the connection between Pin C209-l6, Circuit 617(PK/O), and Pin C208-24, Circuit 624(Y/W), is later repaired, the DTC B1941 will be stored in memory.

Possible Causes
Failure to get low voltage at Pin C208-24, Circuit 624(Y/W), during the test can be caused by:
^ an open circuit in the wiring harness in either Circuit 617(PK/O) or Circuit 624(Y/W).
^ an open circuit inside the RH air bag sensor across Circuit 617(PK/O) or Circuit 624(Y/W).
^ a short to battery or ignition voltage in any of the Circuits 617(PK/O), 619(PK/W), 624(Y/W), or 625(Y/LG).
