You will have to take this to a dealer to shut the air bag light off .. Unless it has been in a wreck at one time or another .. if it has it needs the sensor on front end replaced and the module also reset or replaced.. thanks Jerry and holler if you need more.

My 2004 buick ranier says service air bags the scan says driversside deployment sensor openwhat does this mean and is it real expensive to fix


It means that the ECM thinks the air bag has deployed. Your air bags will not protect you in a crash until this is fixed. I'm not sure if the deployment sensor has a dedicated line on the clockspring ribbon or not. The reason is, that the clockspring is the usual suspect for air bag codes. Since the deployment sensor is not accessible, I would have a professional look at it. Alternatively, some black tape over the air bag light and drive carefully.

2000 CHEVY IMPALA AIR BAG LIGHT ON


  • B0041
CIRCUIT DESCRIPTION
The inflatable restraint side impact module-LF deployment loop consists of the inflatable restraint side impact module-LF, the inflatable restraint side impact module wiring harness, and the side impact module-LF high and low circuits. A shorting bar used within the side impact module-LF connector shorts together the side impact module-LF high and low circuits when the connector is disconnected. This helps to prevent unwanted deployment of the inflator module during servicing. During a side or frontal crash of sufficient force the inflatable restraint Sensing and Diagnostic Module (SDM) allows current to flow through the deployment loop in order to deploy the side impact module-LF. When the ignition is turned ON, the SDM performs continuous diagnostic tests on the deployment loops to check for proper circuit continuity and for shorts to ground or voltage. If a malfunction is detected, a Diagnostic Trouble Code (DTC) will be stored in memory.

CONDITIONS FOR RUNNING THE DTC
Ignition 1 voltage is within the normal operating voltage range.

CONDITIONS FOR SETTING THE DTC
  • DTC B0040 will set when the side impact module-LF deployment loop resistance is less than 1.3 ohms for 500 milliseconds .
  • DTC B0041 will set when one of the following conditions occurs:
  • Side impact module-LF high circuit is less than 2.4 volts and the side impact module-LF deployment loop is more than 6 ohms for 500 milliseconds .
  • Side impact module-LF deployment loop resistance is more than 4.8 ohms for 500 milliseconds .
  • DTC B0045 will set when one of the following conditions occur:
  • Side impact module-LF high and/or low circuits is short to ground or short to voltage for 500 milliseconds .
  • Side impact module-LF high circuit is less than 2.4 volts and side impact module-LF deployment loop resistance is less than 6 ohms for 500 milliseconds .
ACTION TAKEN WHEN THE DTC SETS
The SDM commands the AIR BAG indicator ON via Class 2 serial data.

CONDITIONS FOR CLEARING THE DTC
  • The condition responsible for setting the DTC no longer exists and the scan tool Clear DTCs function is used.
  • A history DTC will clear once 255 malfunction free ignition cycles have occurred.
DIAGNOSTIC AIDS
The following are possible causes of the malfunction:
  • A short between the side impact module-LF high and low circuits
  • An open or a high resistance in the side impact module-LF high or low circuits
  • A short to ground or a short to voltage in the side impact module-LF high or low circuits
  • The side impact module-LF connector
  • The SDM connector
  • A malfunctioning side impact module-LF
  • A malfunctioning SDM

1997 honda civic 1.6L DX SRS Air Bag light stuck on after drove throo heavy rain!


A code reader may not access the body computer, but a professional scanner should. You may be able to research the air bag system online and find a way to make the light flash the codes.
I would guess after reading your description one of the front crash sensors got water in the connector and the sensor has failed.

Air bag light


only possible if the steering wheel bag sensor is at fault
If it is a passenger bag , would not be affected
run the fault codes to determine the exact fault area /sensor

Air bag needs reset in 1998 chevy blazer ls. air bag comes on and goes off while driving down the road.


Chances are it's the airbag clockspring mechanism behind the horn in the steering wheel, they wear out and cause the light to flash. There is no reset for the light. If it's on, you have a short or a bad connection. The clockspring is available at most auto parts stores and installs with a few screws. Make sure you disconnect the battery before you do anything related to the airbag because you don't want it to go off while you are working on it.

B0012 SAYS FRONTAL PASSENGER DEPLOYMENT LOOP. WHAT


B0012 is a fault on the DRIVERS side, you sure you read the code right?
If it is a B0012 then any of the wiring could be suspect the coil or the air bag it's self. I have seen a couple of cars coming with this code and I found the wires coming out of the air bag in the steering wheel to be rubing where they go through the steering wheel into the colume, may want to check there first.
Report back if the code is something else so we can try and assist you.

Air bag light on


the flashing is a code, you need to get a pen and a piece of paper and decode this. It is a two digit number the first set of flashes is the first number so lets say it flashes 3 times and then pauses for 3 to 5 seconds your first number would be 3 and then after the pause it blinks 4 times that would be your second number... so your code would be 34. anyways here is a list of the code meanings so after you count the two set of flashes and get your code compare it here

12=Low Battery Voltage
13=Air Bag Circuit Shorted to Ground
14=Primary Crash Sensor Circuit Shorted to Ground
21=Safing Sensor Not Mounted to Vehicle Properly
22=Safing Sensor Output Shorted to Battery Voltage
23=Safing Sensor Circuit Input Feed/Return Circuit Open
24=Safing Sensor Output Feed/Return Circuit Open
32=Driver Side Air Bag Circuit High Resistance or Open
33=Passenger Side Air Bag Circuit High Resistance or Open
34=Driver Side Air Bag Circuit Low Resistance or Shorted
35=Passenger Side Air Bag Circuit Low Resistance or Shorted
41=RH Primary Crash Sensor Feed/Return Circuit Open
42=LH Primary Crash Sensor Feed/Return Circuit Open
44=RH Primary Crash Sensor Not Mounted to Vehicle Properly
45=LH Primary Crash Sensor Not Mounted to Vehicle Properly
51=Air Bag Diagnostic Monitor Internal Thermal FuseFuse Blown Due to Intermittent Short to Ground
52=Backup Power SupplyVoltage Boost Fault
53=Primary Crash Sensor Circuits Resistance to Ground or Air Bag Diagnostic Fault

It likely is a bad passenger air bag. Did you try switching it back to off on the switch,and unhooking the battery for 5 minutes.

Air bag light


Sounds to me to be a faulty clockspring, have your dealer read the code, they can also estimate the job for you, also, a ten minute battery disconnect usually clears all codes. Disconnect the negitive cable whenever doing any electrical work.
