OK, it appears that there is not a code reader on this planet that will help me figure out the MAINT REQD light that is lit on my 1992 Jeep Cherokee Laredo 4.0 (4 door model) All the code readers I find start reading Jeep (a.k.a. Chrysler) from 1993. I assume that it is an OBD I compliant car, but as I cannot find any GOOD documentation or information on this year of Jeep, I thought there may be another fellow XJ driver who has knowledge on how to read the codes on this car. I love my Jeep and it needs to be registered in August - I am in California, so if ANY warning light is on related to the engine, etc. they will not pass the car. Help me fellow Jeep XJ folks - I don't mind buying a code reader, but not a 0 unit - looking for something more around the .00 mark... Thanks! Northern California XJ Dude
