Code 51 means you have to retrieve the real code from the computer.

Ignition switch should be on with engine off.

Locate the black RABS II diagnostic connector.

Disconnect the two halves.
Attach a jumper wire to the black with orange stripe wire side of the diagnostic connector. Ground the jumper wire ground for a few seconds. ABS lamp should start flashing.


Count the flashes. For example, three short flashes followed by one long flash indicates diagnostic trouble Code 4. The code will continue to repeat itself until the key is turned off. A code of 16 means normal system operation.

The last step of the system test always includes clearing the Keep Alive Memory (KAM).

To do this, simply turn off the ignition while the diagnostic connector halves are separated

Then diagnostic connector should be re-assembled.

After getting the real code, then we can look it up and see what the 51 was trying to tell us to look for.

Air bag light flashes code 51.


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.

F150 wont run


Code 51 is for the coolant temp sensor signal too high - over 250 degrees.
Code 23 is for the throttle position sensor out of range, and code 22 is for map sensor out of range.
Each component and circuit would need to be checked.

My airbag light is flashing a code 51 on my Ford. It sounds like it is as simple as replacing a fuse but I'm not sure where the fuse is located. Also, prior to the 51 code I was getting a 52 code, is this...


Hi there,

Yes, and No....

Although the Airbag diagnostics #51 & #52 are related to the basic fuse/power issue, if you simply replace the fuse, it will continue to blow the replacement fuse until you correctly erase all airbag codes from the computer.

There is a way to do this, without the need for a diagnostic scanner....

If you are technically inclined and can make up a 2 x jumper wires (each with tiny alligator clips on the ends), I can show you how to do this.

If yes, then you need to locate and confirm your data connector is the same as this one (found in the interior fuse box):

Beeps coming from over by the glove box after turning engine off.


the beeps are an airbag trouble code, that code is for the following:
In most cases this problem is caused by the rotating ribbon circuit contact under the steering wheel having a broken filament, the part is known as a clock spring contact, u will need to properly disarm the airbag and remove the steering wheel to access the part. WARNING: Failure to follow factory Airbag disarming protocol can result in an unexpected Airbag deployment and possible serious personnel injury or death.
