TRANSFER BOX CONTROL MODULE INPUTS
The transfer box control module receives the following inputs:
Range change selection switch
High/low position sensor
Transfer box actuator motor temperature
Transfer box actuator motor position sensor
CAN bus messages
Gear position sensor (manual transmission only)
Transmission output shaft speed sensor (manual transmission only).
CAN Bus Messages
The CAN bus is a high speed broadcast network connected between various vehicle control modules. The CAN network
carries an extensive list of messages between the different control modules enabling more sophisticated control with
reduced complexity. Data on the network is packaged for efficient communication and prioritised according the urgency
and importance of the Messages. The bus comprises two wires, which are twisted together to minimise electromagnetic
interference (noise) produced by the CAN messages. For additional information, refer to
