Can you please tell what are these codes for 1997 dodge caravan sport.p1698 and p1495.

P1698 Chrysler

ECM fault-No CCD message from TCM
- Failed ECM

Probable Cause[s]

1. Open CCD bus line
2. Failed TCM

EVAP leak detection pump solenoid circuit condition
- ECM detected the pump solenoid did not change status when activated

Probable Cause[s]

1. Pump solenoid defective
2. Open or shorted circuit condition
3. ECM Defective

P1698= "no CCD messages from the transmission or body controle module (TCM or BCM)"
(The engine control module or ECM is not able to communicate with the two other computers.)

P1495= "Leak detection pump solenoid circuit"
(I believe this pump is the one the EVAP system uses to pressurize its lines temporarily when it does a self check for leaks.)

The p1698 is no message received from the tcm .the po1495 is leak detection pump soleniod circut .what kind of problem is it transission slipping or shifting problem
