Raider V6-3.7L SOHC (2006)
Gear Sensor/Switch: Description and Operation
Transfer Case - NV233 - M/T
SENSOR - TRANSFER CASE MODE <NV233>
DESCRIPTION
The transfer case mode is (1) provides the Front Control Module (FCM) feedback about the position of the transfer case. The sensor consists of a
linear analog position sensor that converts the motor output shaft position into a DC signal. The FCM must supply 5VDC (+/- 0.5v) to the sensor
whenever the FCM is not in sleep mode and monitor the shift motor position. The sensor position is monitored when the ignition is in the RUN
position and for 10 seconds after the ignition is shifted to the OFF position. The sensor is mechanically linked to the shaft of the cam which allows the
transfer case to shift. The mode sensor will draw less than 20 mA of current during operation.
OPERATION
During normal vehicle operation, the Front Control Module (FCM) monitors the mode sensor outputs at least every 2 milliseconds when the shift
motor is stationary or active. Refer to SECTOR ANGLES vs. TRANSFER CASE POSITION for the relative angles of the transfer case shift sector
versus the interpreted transfer case gear operating mode.
