B113D MERCURY Description
Under normal operation, the ground is provided to the rear climate control switch through the circuit. When the switch is pressed, ground through an internal resistor is sent to the Rear Audio and Temperature Control (RATC) module through the circuit. The Rear Audio and Temperature Control (RATC) Module sets the OBDII when the module senses continuous voltage drop on the switch output circuit.
