Damn, you need to go look at a '97 TJ before you post stuff you don't have
direct experience with. The '97 TJ displays the diagnostic codes I already
gave you the link to directly in the odometer, you don't count the flashes.
If you bothered to READ the data on the link I gave earlier, you would see
the codes that the '97 TJ gives DIRECTLY on its odometer. Even though the
flashes also correspond to the numeric codes given in the odometer.

Did you even fawking bother to go to the link I gave earlier to see the
codes? Or did you ignore them because they don't agree with your claim?

But they never lost the ability to store 'P' codes, just as any other OBD II

You fawk, now you're backpedaling. I have been saying all fawking-along
that the '97 TJ DOES NOT DISPLAY P-CODES when displaying its own
codes!!!!!!!!!!!!!!!!! Now you're just saying it "stores" them... which is
NOT the same as displaying them... or what an owner can display without an
external reader.

Since you obviously didn't bother to go to the link I gave you, here are the
codes a '97 displays. The TJ did NOT START DISPLAYING P-CODES until the '98
model year.

COMPUTER CODES

THESE ONLY WORK IF YOU HAVE FUEL INJECTION. Otherwise, see the web site or
the "troubleshooting electronic feedback carburetors" section.

Start with the ignition off. Within five seconds, switch the key on, off,
on, off, on. (On is *not* start!)

The "check engine" light will flash. Count the flashes Each code is a two
digit code, so a (for example) 23 would be FLASH FLASH <pause> FLASH FLASH
FLASH <loong pause>

It will never flash more than 9 times, watch for pauses!
55 is end of codes, 33 is normal if you don't have air conditioning.

When the computer indicates major failure, it will activate Limp In mode,
which guesses about data to compensate for sensor failure.

*** NOTE - NEWER VEHICLES ***

See http://www.ptcruizer.com/computer-codes.html for a new, revised list of
computer codes and instructions on how to get them. These codes appear to
have been phased in starting in around 1998.

***

listing. (From Herb with additions by Charles Hobbs. Basis: Mopar Mailing
List info.)

13* MAP sensor or vacuum line may not be working
14* MAP sensor voltage below .16V or over 4.96V

35 Cooling fan relay circuit open or shorted

OR
solenoid coil circuit (85-89 Turbo I-IV)
OR
Trans temparature sensor voltage low (1995 and on; see NOTE 2)

42 Automatic shutdown relay circuit open or shorted
42 Fuel pump relay control circuit
42 Fuel level unit - no change over miles
OR
42 Z1 voltage missing when autoshutdown circuit energized (SEE NOTE #6)
43 Peak primary coil current not achieved with max dwell time
OR
43 Cylinder misfire
OR
43 Problem in power module to logic module interface
44 No FJ2 voltage present at logic board
OR
44 Logic module self-diagnostics indicate problem
OR
44 Battery temperature out of range (see Note #1!)
45 Turbo boost limit exceeded (engine was shut down by logic module)
46* Battery voltage too high during charging or charging system
voltage too low
47 Battery voltage too low and alternator output too low

51 Oxygen sensor stuck at lean position (lean condition)
OR
51 Internal logic module fault ('84 turbo only)
52 Oxygen sensor stuck at rich position (SEE NOTE #5!)
OR
52 Internal logic module fault ('84 turbo only)
53 Logic module internal problem
54 No sync pickup signal during engine rotation (turbo only)
OR
54 Internal logic module fault ('84 turbo only)
55 End of codes

61 "Baro" sensor open or shorted
62 EMR mileage cannot be stored in EEPROM
62 PCM failure SRI mile not stored
63 Controller cannot write to EEPROM
64 Catalytic converter efficiency failure
65 Power steering switch failure

88 Start of test (not given on most computers)

Did you notice any P-Codes above? Not a fawking one.

Now go back into your hole where you can display your own P-Codes.

Oh... do read the above section marked "*** NOTE - NEWER VEHICLES *** which

Pretty much what I have been saying, that the P-Codes became displayable in
'98... all along.

You asked the OP where he got the 'P' code. Obviously you weren't aware that
the PCM stores them and will report them to an OBD II scan tool. Also obvious
is the OP used a scan tool to retrieve the code.

I told you several posts ago that if you put a scan tool on a '97 TJ, you'll get
a 'Pxxxx' formatted code. You even quoted it in your reply. I guess you don't
read well.

Your claim was the '97 TJ 'doesn't use P codes'. If the PCM 'stores the P code'
and 'reports the P code' to a scan tool, that PCM does indeed 'use P codes'.

I guess a definition of the word 'use' is in order. If you mean it won't
'display P codes in the odometer', then say so. Don't assume I can read your
mind.
