1994 T-100 SR5.
My air bag light is constantly on when the ignition is not in the Lock position. The code I pulled is an 11 (Something wrong). The FSM diagnostic steps are:
From the Center Sensor Connector:
1) Check resistance between +SR and -SR, +SL and -SL. It should be between ~760 and ~880 Ohms (It was).
2) Check resistance between +SR and body ground and +SL and body ground. The resistance should be 1M Ohms or higher.
I have an analog MM. The needle never moved. Is this a pass or fail? I don't know what a 1M Ohm is.
BTW, I tried to clear the SRS Code (something like switching Tc and Ab to ground every second (twice) and leaving Tc to ground (I can't remember the correct interfaces)), but the code wouldn't clear.
TIA
Edit: On #2, the needle never moved... The resistance was okay on #1.
