Where do airbag fault codes usually show up?
Where do airbag fault codes usually show up?
Faults usually occur where people have been working or where heat has been produced by airbag deployment. We have also known low resistance fault codes to show up when airbag connectors have not been pushed fully home and locked into place by the security tab.
How to diagnose and rectify airbag problems?
Disconnecting & re-connecting connectors can resolve an high resistance, in these cases you should apply contact cleaner to that connection or better still remove the multiplug and solder the wires together, ensuring you do them one by one and join the correct wires together, then of course insulate them individually.
How to diagnose airbag problems with a seatbelt?
Airbag or seatbelt not connected properly – Check the component in question is connected properly, especially the connectors with security tabs. Many people push the connector into the airbag by pressing the back of the plug. What this does is it locks in the tab before the connector has gone fully home and in turn creates a bad connection.
Why are my airbag connectors not working properly?
Airbag connectors also contain a ferrite suppressor to protect against accidental deployment. Sometimes these can become cracked and this can cause a low resistance, in this case the connector should be renewed. Sometimes the coil winding around the suppressor can burn out like a fuse and make the circuit go open circuit.
What to do if your airbag harness is damaged?
If the harness is damaged, replace it with a new one.” Per Subaru service information: “If damage, open circuit or rust is found on airbag system wiring harness, do not repair the harness. Always replace the faulty harness with a new genuine part.”

Per the Audi repair manual: “The airbag and seat belt tensioner system can fail. Faulty repairs performed on airbag and seat belt tensioner system can lead to malfunction in passenger protection. When performing repairs on airbag and seat belt tensioner wiring harness, use only terminals, connectors and wires designated for it.
How do you know if your airbag sensor is at fault?
The way you know if the sensor is at fault or not, before scanning your airbag system for faults, is to simply look at the “Passenger Airbag Off” light. If there’s no one in the seat, the light should illuminate.
Why does my airbag light keep coming on?
Faulty airbag sensors are probably the most common cause of airbag lights coming on. Your vehicle has a number of different sensors which are designed to activate the airbag system in the event of an accident. Naturally, these can become faulty, which would cause the airbag light to illuminate.
