Clutch and Range Change Mechanism Calibration

In order for the range change mechanism to function correctly, the transfer box control module must be calibrated to the mechanical dimensions of the transfer box that it is connected to.

This procedure will need to be followed if one of the following occurs:

• The switch is changed
• The transfer box control module is changed
• The transfer box or range position sensor is changed
• Vehicle or transfer box control module fault has caused the transfer box to revert to an undefined range.

Calibration can be carried out using T4.
