I need help replacing my airbag.
the car is an 05 mustang, the airbag deployed after an accident. I have the workshop manual and it said to replace the

1. seat belt
2. clockspring
3. airbag control module
4. front impact sensor
5. airbag

I purchased all the parts from the dealership and I have the workshop manual that the dealership use.

I haven't installed any of the parts

what I want to know is;
can I do it myself and how do you clear the crash error message?

 

You can do it yourself and the crash message can be removed with a normal scanner I had to replace both air bags in my car after i hit a deer only replace the clockspring if the horn and turn signals do not work and the seat belt if it's frayed stretched or ripped the module the bags and the impact sensors all need to be replaced if only one impact sensor was triggered then replace it if not sure replace both and check the fuses there should be two fuses one in the passenger compartment and one in the underhood panel

 

I completed the install and everything looks great.

The first time I install the fuse, the battery, and turn the ignition on, I got an error code. Code 19 (which mean there is a problem with the circuitry), I uninstall everything and checked all the wires and they all looked good.
I reinstall every thing and it works great.

The reason why I got an error the first time was because I didn't follow the instructions on how to repower the system. I guess I was afraid the first time.
I'm going to take the car to the dealership today to have them check the system to make sure everything is O.K.

I appreciate the help.
