The P1698 code means that no digital data is being received by the powertrain controller from the transmission control module, located on the right inner fender. The manual says to check the ccd bus wires between the module and the rest of the system using the Chrysler diagnostic readout box. But if you don't have one then I think you can do the same thing by measuring for continuity (near 0 resistance) between pin 4 of its plug and pin 11 of the data link plug under the dash or pin 59 of the powertrain controller plug.
Then check the resistance between pin 43 if its plug and pin 3 of the data link connector or pin 60 of the powertrain controller plug. The powertrain controller is on the opposite side of the engine compartment on the left inner fender. These module plugs are held in place by a bolt. If the continuity between the transmission and the powertrain CCD wires checks to be ok, then according to the manual the trans controller should be replaced

I would check the connections from the new engine control. Are these codes that show up new or have they not been cleared from a previous problem. Be sure all codes are cleared, Hope this helps. Let me know. Thanks

P1698


This is a code for a internal problem in the power train control module (PCM) It is saying there is no communication. Make sure there is a good connection at the module and the wiring is good. If no problems there then the PCM will need to be replaced.

Make sure you disconnect the battery first.
Make sure the connectors on the PCM/ECM are tight. When removed look for spread terminals, burnt spots, corrosion, etc. Anything that will cause a bad connection

Check engine light is on with code p1698 what is this code


The code P1698 is: No CCD messages from TCM. That means the communication between the Transmission Control Module and the Power Control Module is lost. Sometimes this happens when a PCM, or TCM is replaced without being flashed, a bad connection at the PCM, TCM, or a bad TCM. Hope this helps.

Engine check light


It means that it didn't receive a signal from the transmision module.
Have your transmission control module checked.

To reset your engine codes:
Remove the negative terminal of your battery (10mm wrench).
Turn your ignition key to START and hold it there for about 15 seconds.
Turn your ignition key to OFF and remove it.
Connect the negative terminal of your battery.
