My Airbag light is always on. This four DTC´s are present:

  • B1419 PASSENGER SENSOR 3
  • B1414 DRIVER SENSOR 2
  • B1418 PASSENGER SENSOR 2
  • B1415 DRIVER SENSOR 3

Anybody an idea what can be the reason? And where is the airbag computer located?

What year/Model is it ?

Has that been in a previous accident ?

There are different causes for the light to come on.
Faulty Sensor
Poor Contact @ the Wiring Connector
Pinched or Broken Wiring
Air Bag Deployment Without Reset

A Ford TSB was issued stating techs should used di-electric grease at the air bag sensor's wiring connectors.

I would disconnect the negative cable of the battery before attempting
to unplug any air bag sensor connections.

So many interconnected parts and sensors in these advanced systems.
Persay one of those sensors could be a seat belt pretensioner.

thank you for help. disconnect any plugs, clean them and reconnect w/ silicone grease. Further i performed a cross check, from front too rear and from left too right.
AND NOW IT WORKS!!!!! ;)
YEAH

yes, he was driven in a water ditch by pre owner. So the passenger side was for 2 hours in water. i bought the XP, dried id careful.
Maybe some units has a creeping current but the car has no further fail. The airbags wasn´t triggered

Seems the di-electric grease had an effect on the connections.

Even dried, the wires have the possibility to entrap water inside the insulation.

The water's entry point being where the wire is terminated with a connector.

It may be cost prohibitive ( not worth it ) to try replacing one of the less expensive passenger side sensors with a used one.

Maybe a wrecking yard, replace the cheapest sensor
and if that code goes away you eliminated the suspect of water damage on a passenger side sensor.

Since these sensors are interconnected in the same circuit,
a water damaged passenger side one or water still within the insulation of the wiring could cause a false sensor error to show driver's side faulty.

Electromagnetic induction where a wire's current flow can travel into another wire such as the airbag sensor giving the error code is possible.

This would hold true especially if the wires had water entrapped in the insulation.

Would drive me bonkers seeing the airbag light on but some would just ignore it and
drive on knowing the time, labor and $$$ involved in making it go off.
