I sent all of this to my tech contact at LCI to see what they this is the problem and they were able to come up with a way to use the voltage readings to determine where the issue is:
There are 4 wires on the harness as follows
Black= power (need to see 12 volts)
Green= ground
Yellow= signal wire (need to see 5 to 9 volts)
Red= signal wire (need to see 5 to 9 volts)
If voltage coming into controller is 12 volts but less than 12 volts at touch pad we have a bad controller, # LC242623.
If we have more than 9 volts on the red or yellow wires we have a bad touch pad which used to be available as # LC234802 but currently not.
No words on the touch pad is usually a circuit board issue within the touch pad. I would suggest replacing the touch pad and the system should work again
