Possible Causes






Low voltage at air bag diagnostic monitor Pin 11 can be caused by:

1. A short to ground within the wiring harness on circuits 944A (GN/R), 944 (GN/R), 944B (GN/R), 944C (GN/R), 938 (R), 937 (GY), 939 (GN/Y), 933 (BR/GN), 932 (BR/R) or 931 (BR/BK) causing the air bag diagnostic monitor voltage to drop.
2. An internal short to ground within the air bag sliding contact causing the driver side air bag module circuit(s) to be shorted to ground.
4. An internal short to ground within the safing sensor causing circuit 944A (GN/R), 944 (GN/R), 944B (GN/R), 944C (GN/R), or 938 (R) to be shorted to ground.

NOTE: Circuits 933 (BR/GN), 932 (BR/R) and 931 (BR/BK) are all connected together inside the air bag diagnostic monitor. Therefore, a short to ground on any of these circuits will short all of the circuits to ground.

5. An internal short to ground within one or more of the air bag sensors causing circuits 933 (BR/GN), 932 (BR/R), and 931 (BR/BK) to be shorted to ground.
6. An internal short to case ground within the driver side air bag module or passenger side air bag module.
