REPAIR PROCEDURE FOR AIRBAG FAULT CODE 24 Security Safety Mk3 Mondeo

The first thing any Mechanic should do is check for
SRS Codes (safety restraint system)
They will need a data base to look up manufacture
air bag codes & follow a diagnostic charts to find the issue

The warning chime of 5x5 is a sign that the SRS ( airbag ) light is burnt out, and there is an error with the SRS system.

Verify SRS ( airbag ) lamp operation, turn the key from off to run ( do not start ) the airbag lamp should illuminate. If not, it is burnt out. Need to pull the cluster and replace.
( thread at F150online.com on cluster removal in the how to forum - titled about changing cluster illumination color or installing a cluster overlay ).

Once you replace the SRS bulb, you will get a LFC ( light Flash Code ) of a 2 digit number.
Example :
flash flash flash flash { short pause } flash flash { longer pause } flash repeats the same for 5 times, the solid on.
This is an example of a LFC 4-2. Once you have the LFC start a new problem with the LFC and we can get that fixed after you get the bulb replaced.

it's most likely an error code in your airbag system. Unfortunately, this means a trip to a dealership.
