My A/T s14 is throwing a code 84. Did anybody have this problem? how do I solve it???? Ive got these discriptions on that code:
1. A/T Diag Comm Line (**********)
2. Automatic Tranny-to-Fuel Injection Communication Line
(KA24DEvelopment.com)

I tried switching the A/T control module and it didn't seem to help. I need to clear this CEL for smog! please help.

 

unplug any connections and clean them up a bit. try clearing the codes and see how long it takes for them to come back and what gear you are in when it comes back on
