Coding Resistor
Because of mechanical tolerances in production, the characteristic curve of the multi-disc
clutch locking torque varies slightly.
Once the actual locking torque has been measured on the clutch test bench, a resistor is
attached to the servomotor; the resistor's value is a reference to the locking torque char-
acteristic.
Each time the engine is started, the transfer case control unit measures the resistance
value once and the optimum program map for the transfer case fitted is selected.
Transfer Case Electronic Control Unit
The transfer case control unit (VGSG) is on CAN-bus.
Depending on the vehicle, the module is installed in the following location:
• E60/61 - under the rug foward of the passenger’s front seat
• E83 (X3) - under the rear floor panel of the cargo compartment trim
• E53 (X5) - under the rear bench on the left side
