Mt 51 focus airbag light flashes 4 times repeatedly

If your airbag code is blinking, and you get 51, it means that your internal thermal fuse in your airbag computer is blown which is caused by an intermittant short to ground on one of the wires in the circuit. When the short to the ground is removed, code 51 flashes with the use of the airbag warning lamp, 5 flashes, pause, 1 flash, longer pause. According to the Ford, this is a nonrepairable fix, you must buy a new air bag module which is a blue box located in the vicinity of the the steering column.

this means code 51- Denny

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.

Hi, the airbag light on means your car has the obd2 code problem, you need a tool to read out can delete the code, I know this tool is helpful for your car, or you can take it to the fealer, they will test it for you. hope help.

Replace the airbag lamp in the cluster, and get the LFC ( Light Flash Code ) to figure out what the problem is with the SRS.
The 5x5 beeping is an indication that there is a SRS problem waiting and the airbag light cannot give the LFC. Page 105 in the owners manual.

Once you replace the airbag light, you will get a LFC that is a 2 digit number presented by the flashes.
Example is a LFC of 42, the airbag light would flash 4 times, pause flash 2 times pause and repeat.

Once you have the LFC, either start a new problem, or add a comment to this problem with the number for further diagnoses.

"If you have the airbag light, it will show steady for a few seconds (the manual says 7 secs) after you turn the key from off to on (but not start) and then start to flash. Here is how to reset it:

1. Turn the key from off to on.

2. Watch the airbag light closely. It will stay on for a few secs. and then as soon as it blinks off (the start of the flashing), turn the key off instantly.

3. Count to 5 (1 Mississippi, 2 Mississippi . . . .)

4. Repeat steps 1-3 two more times until you have done the cycle three times.

5. Now turn the key on and watch the light. It will start blinking in a different, slower manner. This is diagnostic mode. You can watch this for a little while, no hurry.

6. Now turn the key off again, Count to 5 like in step 3 again, and turn back on. If the procedure worked, the airbag light will not be flashing.

If it does not work the first time, just repeat the steps again."

Take it to a different shop. Something is wrong with it. However, when the airbag light is on, that means the airbag will not deploy in an accident. You should have that fixed first. The dealership is the best option for making the keyless entry work. If this was at all helpful, please rate. Thanks for asking.

Common fault on FORD

Usually due to a poor connection in the YELLOW PLASTIC CONNECTOR underneath the passenger seat.

Just push it together properly and it should clear the AirBag fault
