Disconnect the battery and reconnect. I heard somewhere it takes awhile for some computer componenets to drain down and completely discharge.

If it looks like this it's a Renix.

If you have a 91 and a HO at that, it's not a RENIX.
That said, 91 was a transition year -- be certain of nothin'.

If it had a learn mode, it would be in learn mode after you disconnect the battery.XJAnthony said:
If it's not renix then it's OBD-I and also don't have learn mode.

To clarify some things:
91 model year was the first year of Chrysler system HO XJs. Renix injection was discontinued in 90 when 91 model year XJs were built and sold.
The picture above is not a Renix XJ motor. The throttle body is an HO TB, easily distinguished by its square base with 4 bolts vs. the Renix unit which has a triangular base, 3 bolts and does not have the "pipe" where the air tube clamps to. The Renix TB is flat-topped. The Renix TB has an adjustabe (carb style) throttle stop on the firewall side. The renix computer is also inside the cab not underhood. The picture is an earlier HO.
I thought the OBD1 should store information about desired engine operation after warmed up and in closed loop mode as long as are no problems causing error codes. If there is a problem, the computer will store the code information until reset or the comp determines the problem is no longer present. The renix uses real time data to run the engine but does not store data or any error codes after shut-down. Its not something you need to worry about really unless the computer isin't getting good information and is throwing codes. Whats the problem anyway?
