I tried to search the forum and the web for the meaning of the trouble code 45 on my Cherokee Limited -96. I have the Haynes repair manual but it lists only code 44 and 46....
Probably somebody here can help me ?
I show 45 Turbo boost limit exceeded (engine was shut down by logic module) but that seems to be for other vehicles. What else did you get? Shold have had at least a 55 showing end of codes.
Yes I got 55 also (and 12 because I have cleaned the battery)
I saw a code 45 somehwere for a -97 and it was something with the NSS. I just want to confirm it. Another meaning for 45 (also "somewhere") was Rich exhaust but I don't think that is the case because I've imported it to Sweden and we have very strict exhaust regulations.
I've looked at the site you mention but can't find the codes for 97... ?
You can't pull the codes for the 97 using the On-off-on-off-on method we can for the 96. There's a section in that linked page for 2001 engine codes, and that lists the 3- and 4-digit codes found with those engines.
I don't have the 96 manual, but I was under the impression that the key codes remained the same, even though the 96 was the first version to use OBDII. Of course they might well have added a code, but if they did, I have found no reference for it anywhere else either.
