Have a 2005 Town & Country and getting no signals on any sensor. Replaced both front sensors due to scanner tools saying no signal from FR and L sensor. FR cleared but the FL still popped on scanner. I checked for signal after replacement and now no signal from scanner on any of the 4 sensors. does this mean my ABS module is bad or am I missing another component?

 

Or you got a bad sensor (bad out of the box). Suggest swapping the sensors and see if issue follows the sensor.
