SOURCE: check enginie light is on code that comes up is p1698 i have no idea what that means and my car seems to be ok

Here is my "take" on the P1698 code:
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. You may be smart however to find an honest shop that has a code reader and let them determine for sure that it is the TCM and not the Powertrain control module (PCM) that is the fault. These modules are expensive enough that you would not want to replace the wrong one.
The other symptoms (1-3) are likely related to the problem because they are also dependent on the digital data communication bus for getting their instructions or sending their information. The passenger side window is probably not related to this, but rather a failed connection, switch or motor.

SOURCE: What does a troubleshooting code of P1698 mean?

The 1698 code can be very difficult. It means that your Transmission control module is not communicating with the powertrain control module. The inst. cluster also uses a twisted pair to communicate. So it could be bad wiring, bad pcm, or bad tcm. My hypotisis would be the pcm but need a good scan tool and ohm meter to make sure.

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.

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.
