My airbag light blinks ten times and pauses then blinks ten times again. I cannot find a 10/10 code anywhere.

Code 10 = Diagnostic monitor internal fuse open due to short to ground. It means there is a short to ground in the SRS system that has blown the internal fuse in the module. It could be virtually anywhere but the most likely would be in the clock spring or an impact sensor. However you need the proper scan tool to see which it actually is. On those it is very easy to accidentally deploy the bag if you start probing the circuits so the testing is done with the scan tool.

Good morning

The airbag code chart is below. Can you verify the blinks for me? There is no code 10.

Roy

The diagnostic monitor is responsible for monitoring the air bag system components and connections. A fault code will be displayed when the ignition switch is in the "run" position and the diagnostic monitor detects a system fault. Certain faults may not be displayed until approximately 30 seconds after the ignition has been switched to the "run" position. This is the amount of time required for the diagnostic monitor to test and verify any and all system faults. The codes are produced by a series of air bag indicator flashes. The fault codes are represented by a two digit decimal number. The two digit fault code will be displayed in this manner: Flash tens digit, one second pause, flash ones digit, three second pause, repeat cycle. For example, a Fault Code 32 will be displayed according to:
flash flash flash, one second pause, flash flash, three second pause,
flash flash flash, one second pause, flash flash, three second pause.

Air Bag Diagnostic Monitor Fault Code Priority Table

The coded fault feature is prioritized so that if two or more different faults occur at the same time, the highest priority fault indication will be shown until corrected. The fault codes and their associated priorities are listed in the Fault Code Priority Table. The codes are ranked from top to bottom with the fault at the top of the list having the highest priority and the fault at the bottom of the list having the lowest priority. This listing is for information only and should not be used for system diagnosis or troubleshooting. The deactivation procedure and diagnostic charts should be used to safely diagnose and service the system.

Note: If a system fault exists and the indicator is malfunctioning, an audible tone will be heard indicating the need for service. The tone produced is a series of five sets of five beeps. The number of beeps does not indicate the fault code, it means the indicator is out and a fault is present.

Steve, Can a guy pick up a scan tool for a decent price? And are they compatible with both OBD1's and OBD2's?

Roy. Double checked with ignition in just run position and then running. I am definitely getting 10/10. What do you make of that?

Mark, A lot of the low priced new stuff is OBD2 only. You could look for a new/used unit like an OTC Genisys EVO or a Snap-On MT2500 brick. Be sure it has the add on cartridge for SRS for Ford/Lincoln though. The brick would likely be cheaper these days. Some of the new Launch and Autel units say they cover OBDI but I have never tried them.

Roy, No problem, Ford sometimes "forgets" to include all of the codes.
