This gives the codes. http://jeephorizons.com/phpbb/viewtopic.php?t=2719
Your underhood emission sticker, and the tire placard in the door jamb will have the date of manufacture. So will the title by the way.

TJ: So, I've got the codes correct?
And oh, is that the link you were finding?

And also, why two same codes? 21.. 21?


Yeah, but there is no underhood emission sticker / details.. and the no placard in the door jamb either.. seems like the PO was on to something..
And Blue, the link you gave doesn't really match my codes.. for example, the code 45, its related to something TURBO, lol... nor do the obd II codes match..
You check the codes and see if I have got them right..?

Yeah, that code 45 is a strange one. The second part "engine shut down by logic module" is noteworthy in that even though you don't have a logic module, your system has stored a "generic" code for an event where the PCM has shut down the engine for some reason. On my more updated codes, code 45 isn't there. http://www.wjjeeps.com/faultcodes.htm I don't know what's up with that.

Well I can tell you 12 will always come up that just says the computer is working And 55 will also always come up that tells you end of codes.

Hmm, are you sure that battery over voltage is related to me?

And what should I check / diagnose to rectify this problem?

45
Trans temperature/ Governor pressure voltage out of range. Less than 1.55 or above 3.73volts for temperature and less than .1 or above 4.89 volts. Trans temp. to high or low. OD switch input too low for more than 5 mins.

21
o2 sensor voltage
I think you have 2 os sensors


they are all votage faults

start with the charging system

code
46 Battery over voltage. could be the cause of all the other codes

get a accurate voltage tester and check the voltage with it running

if you are over 14v running its bad and you need a new alternator

Shouldn't it be 14.4 Volts?

Glad you straightened me out on that code 45 issue. I should have known better than to guess at it. Thanks.
