C Codes diagnostic? Not on list?

[ABlo22]

I have a 2005 5.7 hemi ram 1500. I’ve been testing lights on the clusters and noticed that when I run a C Code test it will cycle between A4, AA, AC, and AE codes every time I test. I can’t find an A4 code anywhere online, and the other ones are sone kind of ABS and PCM issues but I don’t have a clue what that could mean. Any ideas on what’s causing this? Thanks.

what kind of scan tool did you use ?

By the way, if your vehicle is driveable, drive to an auto parts store & ask them if they would use their scan tool to see if your vehicle has any codes .
If they do, ask if they would print out the results, or at least give you the code numbers.

This covers every trouble code,
P = powertrain
C= chassis
U= Network

OBD-II Check Engine Light Trouble Codes

I just used the key trick. All my codes went away after I cycled them around to 99, except for code A4. It’s not on any c code list I can find, I’ll take it in any idea what that could be?
