Airbag SRS warning light resistor 3R3 ohms (5 pack)

Product Information

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? Because to measure resistance, your multi-meter “sends” a reference current through the positive and measures the resulting current after the resistance. 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)! 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.

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. 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 Put some of the smaller heat shrinking tubes over the soldered portion of the needles and the resistor. Maybe you keep having an airbag light come on, perhaps you have fitted an aftermarket steering wheel, maybe you are tired of the seat side airbag connections failing. Of course, there are other possibilities such as wishing to use aftermarket seatbelt reels or you don’t want to pay for an airbag but you want the car to pass an MOT. 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.

With this information, you can then test the component to see if it falls within the required parameters. In the US, having airbag warning lights isn’t illegal, although laws vary from state to state. In the UK, however, having the airbag light on or even flashing is an MoT failure, meaning your car can’t legally drive on the right. Also, in a lot of cases, your car will automatically disable the rest of its airbags when any airbag is causing a warning light. Which could be dangerous. So, here’s how to turn off your airbag warning light. You can test your resistor first to make sure it suits your needs. It should be between 2 and 2.4-2.6 ohms.)

Disappears for a couple of seconds after ignition but then appears and stays 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. It’s a fairly basic system that simply measures resistance. If there is a poor connection, the airbag has already fired, a break in the wire or the airbag is disconnected, the resistance will be very high. If 1 of the wires is short circuiting then the resistance will be very low. Either way, the light will come on. The Right Resistance

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 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. 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. I am currently awaiting an opportunity to install my old pretensioner into the replacement seat and then attempt to clear the codes and reset the warning light. I will let you know how I got on. After this there are few options. There is a sensor under the seat to tell if the seat is being sat on, and the side airbag. The side airbag would be obvious if that had gone off.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. I tried putting a 2.5 ohm resistor in the plug instead of connecting it to the new airbag but light still comes on.

Once you know what resistance should be in a particular airbag circuit, then you can test the component to see if it is within tolerances. 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. 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.

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. Once the resistor tool is set at the correct resistance value, then the codes will erase and the airbag light will remain off which indicates you have found the correct resistance value that should be in that circuit. 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.
