texasbudman Posted October 24, 2007 Share Posted October 24, 2007 Good Day, I've had gremlins in my Pathy lately and have just been introduced to the codes (thanks again)... however after reviewing the list I noticed that some are duplicate... any special reason why???? I honestly didn't even know the lil box was for, but I'm a learnin!! Anyhow I won't get the chnace to ck it out till Sat, but if anyone has a heads up please let me know... any useful informaiton is much appricated...

88pathoffroad Posted October 26, 2007 Share Posted October 26, 2007 I believe duplicate codes are for partial failures or total failures. Missing numbers may simply have not been used by Nissan, who knows? Link to comment Share on other sites More sharing options...
unccpathfinder Posted October 26, 2007 Share Posted October 26, 2007 i would think missing coedes were probably in the prototype ECMs and they decided to not need them and got rid of them for one reason or another...I know when I was at freightliner they did things like that...the other would be that they started with lines 1 5 10 15 and added codes as they went (you generally do this in CNC coding in case you need to add something and it makes it easier) Link to comment Share on other sites More sharing options...
texasbudman Posted October 26, 2007 Author Share Posted October 26, 2007 Okay guys... sounds good to me... you could have made the whole thing up... I wouldn't have a clue... but it make me feel better... So Thanks... But lets assume that one is partial failure and the other is total failure... is it also safe to assume that the first would be partial and the second total???? Thanks agian...
