You will probably get much better information by calling the company that makes the scanner than by posting in this forum.

I hope you get it working!

I didn't think the XJ was OBDII until mid 97, but I could be wrong...

EDIT: Nope, I'm right, yours is OBD I

Nope, my 96 was OBD-II.

My son's 96 is both obd I and II. It would not otherwise have the OBD II socket. My code scanner works on it. Make sure the ignition is all the way on.

Renix rigs have the same socket, it does not make them obd II

OK, I am resigning... I have seen conflicting information, but I will concede that allpar.com states:

Finally, in 1996, the engines were made quieter and given more usable torque with several air path changes; the Selec-Trac system was upgraded; OBD II on-board diagnostics were added; the powertrain control module moved to the JTEC system; and a revolutionary returnless fuel supply system, first seen on the Neon, was installed.

Good Luck!

The engine control system has diagnostic capabilities. Using
System Tester (M.S. 1700), diagnostics can be performed on the system
to more accurately determine faulty components. The diagnostic
connectors are located in the engine compartment at the right shock
tower (or under left side of instrument panel).
NOTE: Information for diagnosing the engine control system using
the System Tester (M.S. 1700) was not available from
manufacturer. Only component testing is provided.

Those are not the same as the OBDII connector as your earlier post says.

96s are obd2s. The scanner's auto-detection of the Jeep protocol might not quite work, so you might have to go into a menu and select it manually(I can tell you what mine is if I go get mine). As Matt said, make sure ignition is on(even though my dad's scanner has steps to turn the scanner on and then prompts you to turn on ignition when it is ready). Mine's a 1/96 btw

check fuses..... I remember having a fuse blown on my 98 which prevented me from reading the odbII data but the jeep ran without showing that anything elkse is wrong with it.

You're right... I had not looked far enough into it to make that statement. I still thought they were OBD I until mid 97, but I was wrong about that too... It is was still OBD I compatible (I do know that because my 97 gives OBD I codes through the odometer) but it gives chrysler OBD II codes if you have a scan tool. As I said, I was wrong, and thank you for pointing that out to me, I learn alot while researching to try to help others.

Congress mandated that all vehicles sold in the United States be OBD II compliant by January 1996. SO if his XJ is a 96, it is OBD II. If your reader is not working then your computer may be shot.
