Question about 1997 Dodge Grand Caravan
The P1698 code means that no digital data is being received by the powertrain controller (on the left inner fender) 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 .
Then check the resistance between pin 43 if its plug and pin 3 of the data link connector. Finally check continuity from pin 7 of the data connector and pin 65 of the powertrain connector (pink wire). If the continuity between the transmission and data link connector wires checks as well as from the connector to the PCM proves to be ok, then according to the manual the trans controller should be replaced. But you should also verify that there is either a + or - bias voltage of 2.5 volts on each of those wires as a loss of bias voltage will also cause this code.
