Possible Causes

Higher than normal voltage on Pin 11 can be caused by:

1. An open in one or more of the circuits between the air bag diagnostic monitor and the air bag sensors. Circuits 933 BR/GN, 932 BR/R, or 931 BR/BK may have an open circuit in the wiring.
2. An abnormally high resistance value across one or more of the air bag sensors. One or more of the air bag sensor resistors may have too high resistance or may be a completely open circuit.
3. An intermittent open between the positive terminal of the battery and Pin 13 may cause the air bag diagnostic monitor to determine that voltage on Pins 17, 18, and 19 is too high with respect to the voltage on Pin 13.
4. Resistance across the safing sensor. The safing sensor is a normally open switch with infinite resistance across its contacts. If the safing sensor is faulty and some resistance builds up across the open contacts, the voltage on circuit 943 (BL) will pull up the voltage on circuit 944A (GN/R).
