I think you have a false code stored due to your work. clear the code and you should be ok.
If the air bag indicator does not illuminate or the indicator stays on or flashes at any time, a fault has been detected by the air bag diagnostic monitor.
Diagnostic trouble codes (DTCs) may not be displayed for approximately 30 seconds after the ignition switch is placed in the RUN position. This is the amount of time the air bag diagnostic monitor requires to perform all tests and verify system faults.
Each DTC (a series of flashes and pauses of the air bag indicator):
- Represents a two-digit number.
- Is always displayed at least twice.
If the diagnostic monitor detects a fault in the air bag system, a diagnostic trouble code (DTC) will be written to the diagnostic monitor's Non-Volatile RAM (NVRAM). This DTC will then cause the lamp to flash a lamp fault code (LFC) on the air bag warning lamp and can be retrieved with the New Generation STAR (NGS) tester. After servicing the DTC may then be cleared from the NVRAM.
If a system fault is present and the air bag indicator is malfunctioning, an audible tone will be heard. The tone is a series of five sets of five beeps. If the tone is heard, the air bag system needs attention.
If a fault exists that makes unwanted air bag deployment possible, the air bag diagnostic monitor will attempt to remove deployment power by turning on a solid state switch to blow the 10A battery fuse.
If the 10A battery fuse has successfully been blown by the air bag diagnostic monitor, the air bag diagnostic monitor will not attempt to blow it again until the proper fault has been repaired and cleared (refer to Diagnostic Instructions). The air bag diagnostic monitor will store both the unwanted deployment diagnostic trouble code and the loss of deployment power diagnostic trouble code. The loss of deployment power diagnostic trouble code is the highest priority.
If a fault exists that makes unwanted air bag deployment possible, the air bag diagnostic monitor has an internal fuse that that will blow (open) automatically. This removes all power to the air bag deployment circuit.
DTCs are prioritized numerically. If two or more faults occur at the same time, the fault having the highest priority will be displayed first. After that fault has been corrected, the next highest priority fault will be displayed.
The air bag diagnostic monitor includes an internal backup power supply. This feature provides sufficient backup power to deploy the air bag in the event the battery (10655) or battery cables are damaged in a collision before safing and air bag sensors close. The backup power supply will deplete its stored energy approximately one minute after the positive battery cable is disconnected.
Once a DTC is logged into the air bag diagnostic monitor memory, it will stay in memory until 80 key cycles have been recorded or until the NGS is used to erase the DTCs. Once 256 key cycles have been recorded since the concern was last detected, the DTC will automatically be removed from memory.
Active Command Modes
This command allows the technician to verify operation of the air bag system, indicator and tone. When the air bag output command is executed, the indicator and the tone are simultaneously activated for approximately four seconds. Both devices are automatically deactivated.
