Charger V6-3.5L (2009)
Resistances in these ranges will be represented as a Neutral Switch Activation.
TRANSFER CASE MODE SENSOR SIGNAL
The Transfer Case Mode Sensor Signal Input will provide the DTCM feedback about the position of the transfer case. The mode sensor is a linear analog
position sensor with a 1.4K +/- 20% potentiometer and a 1 K +/- 20% wiper resistor that converts the motor shaft position into a multiplexed voltage.
The mode sensor (on the active transfer case) is an active device where the sensor's current changes as the motor shaft position changes
TRANSFER CASE BI-DIRECTIONAL MOTOR CONTROL (A AND B)
This output will control a Bi-directional DC motor that controls a clutch pack in the Transfer Case that varies the torque transfer between the front and
rear axles.
MODES OF OPERATION
Normal Operation
This mode is achieved by the ignition being switched in the RUN position, which powers up the 5V regulator and generates the appropriate RESET for
the microprocessor. This mode also includes any required power-up system checks.
Shut Down Mode
This mode is activated when the ignition switch turned to the off position. The DTCM will perform any required Shut Down tasks prior to turning off the
5V regulator.
Limp-In Mode
This mode is entered when the DTCM has detected an error condition that prevents the system from performing its required task. The DTCM operation
will vary depending from modified operation to total system shut down based on the failure that has occurred.
