There are other saftey features in the car that activate in the event of a crash. Most likely in your situation an accelerometer that shuts off the fuel has been tripped. These work in 360 degrees and will trip even though the air bag is still not actuated.

Cars like Ford Fiesta have a reset that is in the glove compartment and can be reset by the DIY owner.

Check manual and web for your car. Usually located in passenger department.

Hope this helps?

When a vehicle cranks and does not start it is one of two causes, either electrical or fuel. The first is to check the spark plugs are they seated properly, if there is a spark check the distributor for any worn electrodes. If both those are fine the check the fuel pump is working and delivering fuel. It would help if you gave a description of the vehicle.

Service Air Bag light on


DTC B0058 Right Front/Passenger Pretensioner Deployment Loop Open.
The passenger seat belt pretensioner deployment loop consists of a seat belt pretensioner-RF and the seat belt pretensioner-RF high and low circuits. A shorting bar used within the seat belt pretensioner connector shorts together both the seat belt pretensioner high and low circuits when the connector is disconnected. This will help to prevent unwanted deployment of the pretensioner during servicing. During a frontal crash of sufficient force the inflatable restraint sensing and diagnostic module (SDM) will allow current to flow through the deployment loop in order to deploy the seat belt pretensioner. 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.
DTC B0084 Left Front/Driver Seat Position Sensor Circuit
The inflatable restraint seat position sensor (SPS) is used to determine the proximity of a front driver or passenger seat position with respect to the frontal air bag. The SPS interfaces with the sensing and diagnostic module (SDM). The state of the SPS allows the SDM to disable stage 2 of the frontal air bag for a front seat that is forward of a forward/rearward point in seat track travel. The SPS is a hall effect sensor that is mounted on the inside seat track of both the driver and passenger seats. The seat track includes a metal bracket that shunts the SPS magnetic circuit creating 2 states of seat position. The shunted state represents a rearward seat position. The non-shunted state represents a forward position. The SPS provides 2 current ranges, one range for the shunted state and a second range for a non-shunted state. These 2 states are inputs to the SDM. State 1 (shunted) being the rearward threshold and state 2 (non-shunted) being the forward threshold. When the SDM receives input from a SPS that state 1 threshold is reached (seat is rearward) the SDM will not disable stage 2 deployment, if required by the deployment sensors. When state 2 threshold is reached (seat is forward) the SDM will disable stage 2 deployment on the side the seat is forward. The SDM monitors the SPS circuit and if a fault is detected the SDM will set codes B0083 or B0084 and defaults to disabling stage 2 frontal deployment. This will only default on the side of the vehicle the sensor has a fault. Its important to understand that the SPS is secondary to the passenger presence system (PPS) and the manual instrument panel (I/P) module disable switch. If either one of these devices are in the disable mode the passenger air bag will not deploy regardless of the SPS status.
You should take this to a qualified repair Shop ! Takes special tools to test .

Car wont start after accident


Some vehicles have an impact switch that shuts the fuel of, in event of an accident, give your Honda dealer a call they should be able to tell you how to activate it

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

My ex husband was in a roll over car accident in his 2006 ford fusion going 70 mph and his air bags didnt deploy. is there a recall on those or does he have a possible case for his injuries?


Front air bags are not designed to deploy in side impact, rear impact or rollover crashes.There are several reasons why your air bag may not have deployed during a crash. The first reason is that perhaps your crash is not the type of accident where air bag deployment would be helpful. For frontal air bags, this includes many, but not all, side impacts, rear impacts and rollovers. This category also includes minor accidents in which the driver and front passenger (if there was one) did not suffer any significant injuries requiring medical treatment. Many people do not realize there are a lot of side air bags that do not deploy during a rollover accident, even when the vehicle rolls onto its side. That is because those side air bags do not include an appropriate crash sensor that can detect rollover crashes.

Front impact crash & airbag did not diploy


Airbags have specific criteria for deployment that determines whether impact was severe enough to deploy bags or whether only 1 stage deployment is needed or may decide impact was minor enough that deployment of airbags could potentially be more dangerous than the actual impact. For instance I was on the expressway last year going 65mph and someone rear ended me at over 100mph. Totaled my Ford Focus, her airbag did not deploy. Over certain speeds depending on the vehicle calibration, and airbag should never deploy. With an impact under a designated speed or over a designated speed a deployment can be dangerous. As long as your airbag light was not on before the crash I'd say your system was working properly and did not malfunction. If your airbag light ever comes on just keep in mind that any airbag malfunction will disable the system and turn on the light

Airbag locations


In the steering wheel and passenger side dash.Due to the age of the vehicle probably doesn't have the curtain "side" airbags.The airbags were designed primarily for head on collisions. Here is some useful information to why the may have not deployed courtesy of http://www.asashop.org/autoinc/dec2001/collision.htm
How Air Bags Work To have a frontal (driver or passenger) air bag deploy, certain criteria must be met. One of these criteria is that the frontal impact must be within a 60-degree window, occurring within 30 degrees from the vehicle's centerline. Another key element is that the crash forces are equivalent to a head-on collision with an immovable barrier at 10-15 miles per hour. Because a typical automobile accident only lasts about 0.125 (1/8th) of a second, air bags deploy within 15 to 20ms after the initial crash impact. To create a protective cushion between the occupant and the vehicle's interior, the air bag inflates at speeds up to 200 mph within approximately 30ms after impact. This allows the occupant to contact a fully inflated bag within approximately 45 to 50ms after the initial crash impact. Approximately 100ms after impact the bag deflates.

Slid into a ditch and hit a fence post with front end... no damage to car air bag did not deploy... now car wont start... I have a 1995 chevy lumina


is there an inertia switch? if there is it trips when there is an impact and cuts the power to the fuel pump. check if you have one and reset it.

Where are the airbag sensors on a 2002 Malibu? Daughter ran off road, hit ditch & did damage to right front from headlight down....both airbags deployed...is that normal?


Hi, the impact sensors for the air bags are usually located between the headlights more or less at the lowest point of the headlights. It is possible that the air bags will deploy as the impact sensors work with vibration. If the vibration is big enough to activate the sensor the air bags will deploy.

ABS engages everytime,just before a full stop,on dry road conditions...2002 Envoy SLT .This happened after a front collision at a speed of 30kms.Air bags did not deploy...minor frontal damage.ABS light...


It might be a coincidence and nothing at all to do with the impact.

Lots of modern cars have abs reluctors built into the wheel bearings. This is because the external type tends to be eroded by salt and water increasing the abs sensor air gap so at low speeds an output will be lost and the brain will assume a wheel is locked and deploy the abs.
Sometimes a scale and corrosion build up will split the reluctor ring.

Before seeking more complicated solutions it would be well to ensure any exposed reluctors, sensors, air gaps and wiring at each wheel is in good order.
