Code 1698 is for a problem with the computer not getting a signal or data stream from the transmission control module.
The problem could be the module or the wiring between the two components.

Check engine light code p1698


A p1698 means the pcm is not recieving a bus message from the tcm. The vehicle bus is one wire that runs to each module as there means of communication. Could be a broken wire, bad connection, or possibly a bad module. Unless your pretty sure about what your doing and have some good wiring diagrams you should probably take it to your dealer.
