Rearm impact sensor

[Iceman1211]

Hi

Hope your well, I had a wheel bearing fitted on Saturday and drove the car home and it developed a fault saying re arm impact sensor. When you turn on the engine the hazard lights flash until there turned off and I get a warming in the dash if re arm impact sensor. They hasn't been any accident in the car and the car drives fine. I have been told to reset the red button under the bonnet did that but didn't cure the problem.

Can any1 help

Thanks

Welcome Iceman....

What car is this please?

As Jim says (Welcome! ) need to know what vehicle / year.

The red button is probably the inertia switch which is a magnet and a steel ball in effect, sometimes they can be set off by potholes etc. I doubt its that or it would not run.

It sounds like the SRS ecu but I did not realise they were resettable easily without internal intervention. I also recall some models can flash hazards under extreme braking force as a 'warning' to following road users, ie having to suddenly lose speed on a motorway etc.

Its a faulty inertia switch (the red button under the bonnet). You need to replace it, resetting it wont work.
