    My airbag light comes on and off when braking and driving kinda irritating after a while. If you disconnect the fuses then the light just stays on. Tempted to just put electrical tape over light and disconnect the fuses.

Air bag light on


see this and fix it.
AIR BAG SENSOR REPLACEMENT Several very important points must be kept in mind about replacing crash sensors. One is to make sure the replacement is the correct one for the application. Crash sensors are calibrated for specific vehicle applications, so compare OEM part numbers to make sure your parts supplier has given you the correct replacement crash sensor.
The mounting of the crash sensor is also critical. A replacement sensor must be installed in exactly the same location and the same position as the original. The sensor must also be firmly attached so it won't break loose in a future collision. Altering the mounting location or position of a sensor may cause it to trigger the air bag accidentally or not at all.

CRASH SENSOR CHECKS The air bag control module self-checks the crash sensors every time the engine is started, so unless the air bag warning light is on the sensors are assumed to be okay. If a fault is detected, the air bag warning light will come on and usually deactivate the air bag system. Using a scan tool, you can pull the trouble code from the system and refer to the appropriate diagnostic chart in a service manual to troubleshoot the problem. Air bag service information can also be found on the vehicle manufacturer's website (Click Here for a list of websites and access fees). Loss of circuit continuity anywhere in the air bag system, or loss of power to the air bag module are common causes of trouble codes.
Because crash sensors are sealed units, you cannot always determine their true condition by outward appearances. Any sensor that is obviously sustained physical damage as a result of a collision or other damage should be replaced. But what about ones that look okay? Most electromechanical crash sensors are designed to be electrically open in their rest condition. So one quick check you can perform is to check for continuity with an ohmmeter. If the sensor contacts are closed, it has not reset and should be replaced.

I have a code that show on CARMD about the srs light (airbag) on my dash , how do I reset or shut it off without changing an airbag


Hi there:The Restraints Control Module (RCM / located behind right side of the instrument panel) monitors the resistance of the driver side air bag circuit loop and the air bag module igniter at RCM, if the resistance is greater than 3.6 ohms, the RCM will store diagnostic trouble code B1994 and flash lamp fault code.
About the possible causes, pay attention that a high resistance on the driver side air bag circuit can be caused by:
  • - damaged wiring on circuit 1257 (WH/LB).
  • - damaged wiring on circuit 1258 (BN/LB)
  • - damaged driver side air bag module.
  • - damaged RCM.


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Air bag warning light permanently on on the dash board


  • The Air Bag Warning light on your dashboard functions just link a check engine light does. When it comes on and stays on there is a issue and the only way to know is to get it Airbag Control Module scanned by a VAG com scanner.
  • I don't know if Auto Zone can scan this but it is worth a try as they are free. If they don't then you will have to go to a repair shop and have it scanned. Once you get it scanned you will know what is causing the Air Bag Warning light to stay on. Then you can post it hear and I can assist you further. There is really know way to know until it is scanned.
  • Hope this helps and thank you for using FixYa.

2001 Escort ZX2. Where are the impact sensors loctaed for the front air bags? Also, where is the control module located?


AIR BAG (SUPPLEMENTAL RESTRAINT SYSTEM) General Information The Supplemental Restraint System (SRS) is designed to work in conjunction with the standard three-point safety belts to reduce injury in a head-on collision. WARNING
The SRS can actually cause physical injury or death if the safety belts are not used, or if the manufacturer's warnings are not followed. The manufacturer's warnings can be found in your owner's manual, or, in some cases, on your sun visors. Depending on your vehicle, the SRS may be comprised of some or all of the following components:
  • Driver's side air bag module
  • Passenger's side air bag module
  • Air bag diagnostic monitor computer
  • Left and right-hand radiator primary crash air bag sensor and bracket
  • Center cowl safing rear air bag sensor and bracket
  • Left-hand kick panel safing rear air bag sensor and brackets
  • Air bag warning indicator
  • Tone generator (internal to the air bag diagnostic monitor)
  • Electrical wiring
  • Air bag Electronic Crash Sensor (ECS)
The sensors in the car are designed to detect a severe frontal impact. When at least one of the primary crash sensors and the center cowl safing rear air bag sensor close at the same time, electric current flows to the inflator and ignites the chemicals. The chemicals burn rapidly in the metal container. This burning produces nitrogen gas and small amounts of dust, both the gas and dust are cooled and filtered during the air bag(s) inflation. The air bag(s) split the trim covers open while inflating. The air bag(s) then rapidly unfold and inflate in front of the driver or passenger. After the air bag(s) have inflated, the gas escapes through holes in the bag(s) and the they will deflate. prev.gif next.gif

Dash lights went out, so i had some fuses removed to see which one was bad. next thing i know the airbag light was on.


You just need to turn it off again. You created a false trigger of the light. You may have to have dealer do it with scan tool.


Prove Out Procedure
Turn the ignition switch from the OFF to the RUN position and visually monitor the air bag indicator with the air bag modules or restraint system diagnostic tools installed. The air bag indicator will light continuously for approximately six seconds and then turn off. If an air bag supplemental restraint system (SRS) fault is present, the air bag indicator will either:
  • fail to light.
  • remain lit continuously.
  • flash.
The flashing might not occur until approximately 30 seconds after the ignition switch has been turned from the OFF to the RUN position. This is the time required for the restraints control module (RCM) to complete the testing of the SRS. If the air bag indicator is inoperative and an SRS fault exists, a chime will sound in a pattern of five sets of five beeps. If this occurs, the air bag indicator will need to be repaired before diagnosis can continue.
----------------------------------------------------------- Restraints Control Module (RCM)
The restraints control module (RCM) performs the following functions:
  • signals the inflators to deploy the air bags in the event of a deployable crash.
  • monitors the air bag supplemental restraint system (SRS) for faults.
  • illuminates the air bag indicator if a fault is detected.
  • flashes the air bag indicator to indicate the lamp fault code (LFC) detected.
  • communicates through the data link connector (DLC) the current or historical diagnostic trouble codes (DTCs).
  • signals the generic electronic module (GEM) to activate a chime if the air bag indicator is not available and another SRS fault exists.
NOTE: The safing sensor is internal to the RCM and is not repaired separately.
The RCM monitors the SRS for possible faults. If a fault is detected while the ignition switch is in the RUN position, the RCM will illuminate the air bag indicator located in the instrument cluster.
When the ignition is cycled (turned off and then on), the air bag indicator will begin its prove out sequence. During prove out the air bag indicator will illuminate for six seconds, go off for two seconds and then, if a system fault exists, flash the two-digit LFC. The air bag indicator will flash the LFC five times, then it will remain illuminated for the rest of the key cycle. The RCM will also communicate the current and historical DTCs through the DLC, using a scan tool. If the air bag indicator does not function, and the system detects a fault condition, the RCM will signal the GEM to activate an audible chime. The chime is a series of five sets of five tone bursts. If the chime is heard, the SRS and the air bag indicator require repair.
LFCs are prioritized. If two or more faults occur at the same time, the fault having the highest priority will be displayed. After that fault has been corrected, the next highest priority fault will be displayed.
The RCM includes a backup power supply. This feature provides sufficient backup power to deploy the air bags in the event that the ignition circuit is damaged in a collision before the safing and air bag sensors determine that deployment is required. The backup power supply will deplete its stored energy approximately one minute after the battery ground cable is disconnected.
Electrical System
The electrical system that supports the air bag supplemental restraint system (SRS):
  • is powered from the battery through the ignition circuit.
  • provides the electrical path from the restraints control module (RCM) to the air bag modules.
  • provides the electrical path from the RCM to the air bag indicator.
  • provides the electrical path from the RCM to the data link connector (DLC).
  • provides the electrical path from the RCM to the generic electronic module (GEM).

It beeps and there is no lights on the dash


make sure your air bag light is operating. if the airbag light is burnt out on the instrument cluster, it will beep an audible tone to let you know there is a problem since there is no working warning light. turn key on (but dont start vehicle) and see if the air bag light comes on and shuts off (its called "prove-out") if it does not come on at all, chances are... the light for air bag warning on cluster is burnt out

Air Bag Indicator Light blinks on 1995 Lincoln Town Car


The blinking light is giving you a code and according to what you have listed that would be a code 25. However there is no code 25 for this system are you sure that it is not a 52 instead? If so then this code is for a loss of power to the module. Did you have battery go dead recently? If this is the case then you can clear it yourself. You will have to locate a gray 2 wire connector behind the glove box first. Here are the instructions to clear the code 52.
  1. Cycle the ignition switch to OFF and then to RUN.
  1. Observe air bag indicator prove-out (six ± two seconds) followed by diagnostic trouble code (52-85) flashing completely one time.
  1. Locate the Diagnostic "Trouble Code Clear" Connector located underneath the glove compartment (06010) containing Circuits 631 (T/R) and 57 (BK).
  1. Use a jumper wire to short Circuit 631 (T/R) to Circuit 57 (BK) or to another good ground. This short must be made after the diagnostic trouble code flashes completely one time, but before the warning light stays on continuously.
  1. Hold short until air bag diagnostic monitor tone sounds (approximately five seconds).
  1. Release short on Circuit 631 (T/R) to Circuit 57 (BK). This short must be released within 25 seconds after the diagnostic monitor tone sounds.

Air bag light flashes 5 times then2 times how to reset light have tried leaving battery disconnected overnight to no avail.light started after removal of fuses to check for power to rear wipers.


CLEARING CODES (works for code 52)
1. Only intermittent codes and codes that diagnostic monitor recognizes as being repaired may be cleared from memory. To clear codes, cycle ignition OFF to ON. Observe AIR BAG warning light. AIR BAG warning light will illuminate for 4-8 seconds, and flash fault code.

(Comment) Loosely translated - If you dont have the problem fixed, this wont work. Code 52 should clear with this!

2. Locate air bag diagnostic 2-pin connector.

(Comment) This was a fun one. According to the air bag wiring diagram that I also got from Mitchell, the Airbag Diagnostic Connector is located "Right side of Instrument Panel". The only thing I found immediately to the right of the I/P (between the stereo and Instrument panel) was a black computer with 4 connectors which is NOT what I was looking for. I finally found a blog that mentioned the computer for the air bag computer was behind the right side kick panel. Sure enough....there it was. Attached to the side of the diagnostic computer was a two prong diagnostic connector.

3. Connect a jumper wire between diagnostic connector terminals. Leave jumper wire connected until diagnostic monitor tone sounds (about 5 seconds). Disconnect jumper wire. Fault code is cleared.
