XJ's with HO engines do, so I'd think your MJ should too.

It should flash the check engine light for the codes. For example: flash-pause-flash-flash is 12 (battery disconnected). They always flash 55 (flash-flash-flash-flash-flash-pause-flash-flash-flash-flash-flash) for end of codes. You have to watch it closely, I had to do mine a couple of times before I got the hang of it. My 97 TJ and 2000 Neon are much easier, they put the codes on the digital odometer.

You have to flip the key on-off three times in something like 2 seconds, ending with it in the on position.
