Hello all. New to 
and new to XJ's. Bought a 96 XJ 4.0 aw automatic 4 speed 4x4 with 90k miles. Was a one owner vehicle and is super clean. I got it from the junk yard for $900 so i thought it was a steal. It appears it got sent there cause it wont pass the California smog test. I tuned it up and it ran great. Passed the sniffer part with no problem it had ultra low numbers compared to the max allowed, but it wont pass the inspection because of fault code p1694. and it reappears right after being cleared. I did the crank pos. sensor which was also needed, and have since ohmed out the blk/white and purple/brwn wires between the ecm and tcm. Is there any other reason that this code is recurring. Is there any other trouble shooting i can do before replacing the tcm. Otherwise all gauges work and there are no other issues. When i got it the tcm was hanging down and the harness under the hood had been opened up so its not a new issue. The tcm i have with it is part number 56027951, I'm wondering if it is the original. maybe some replaced it and its not the correct number. Any help would be much appreciated. I cant wait to get this vehicle on some trails.
