With this information, you can then test the component to see if it falls within the required parameters. It desperately needs to go for an MOT soon as it has expired and is parked on the road. I do not know anyone who would turn a blind eye to the airbag light being on.

If 1 part of this system is not connected, there is a fault with a connection or the airbag itself, you will get a light on. Il aide au diagnostic d'un airbag défaillant, d'un ressort d'horloge d'airbag et de tendeurs de ceintures de sécurité défaillants, etc. If this light is on, none of the safety features will function when required to do so. In a crash, none of the airbags will fire and the seatbelts will not pretension. How Does It Know? Simply remove the component you are working on (eg: airbag or seatbelt etc) &connect the two wiresinto the wiring loom connector in place of the component. I have read about resetting the airbag ecu, replacing it, replacing just the pretensioners, replacing it all. I don’t want to just throw money at it until it’s solved as the parts are expensive and also could do with resolving the problem swiftly, so am hoping someone can point me in the right direction to finding what the fault is and getting it working properly.

I tried putting a 2.5 ohm resistor in the plug instead of connecting it to the new airbag but light still comes on. If you use a push-pin, cut it so the two tips of the push-pin are sharp. if you use sewing needles you can just leave them as they are. You can test your resistor first to make sure it suits your needs. It should be between 2 and 2.4-2.6 ohms.) Unfortunately it’s not a ‘one size fits all’ solution with resistors. They all have different values of resistance (measured in OHMS) and this needs to be specific to match the resistance of the airbag you’re taking out of the circuit. The value generally changes between car models and manufacturers so a little forum hunting will be needed. Don’t worry too much though – someone has always done it before. Where to get the resistor This video will show you step by step instructions on how to make a DIY airbag tester so you can test your airbag without the need for an expensive airbag tool.

I've had a look under the passenger seat but plug all looks connected up and secure. Seat belt hasn't retracted and can still be used.

If your not sure if either pretensioner is functional you can test them with a volt/ohm meter as shown at https://www.youtube.com/watch?v=dsOM58mBM7Y For example, if you were carrying out diagnostic work on a seatbelt pretensioner circuit and needed to know the correct resistance valuein that circuit then this tool would help you identify it. I took it to the dealer to get the crash module reset - this stopped the hazards turning on when I turned the ignition on. They also said the following fault codes were present: Curve the wire just before the resistor and measure the length between the other end of the resistor and the tip of the needle we just weld.

Hi. I have a 2005 Expert which has the airbag light on. It has the seatbelt pretensioners on the belt itself in the B pillar and drivers airbag only. I have been struggling to find information due to the sheer amount of different vehicles and all the results I can find are either for newer models or for pretensioners on the receiver stalk rather than on the belt.

Depending on the car model and multi-meter model, the reference current could be high enough to deploy the airbag, which could be potentially deadly or harmful (trust me, if you never saw an airbag deploy before, you don’t want to be holding it when it happens)!

Put some of the smaller heat shrinking tubes over the soldered portion of the needles and the resistor. Some vehicles will require the use of a diagnostic scan tool along side the resistance tool as you may need to erase the fault codes until the light goes out.
