CIRCUIT OPERATION1
CIRCUIT OPERATION
Interface to transfer motor inside Transfer Box
(X313)
The Transmission Gearbox Control Unit (Z256) has
a seven wire interface to the Transfer Motor inside
the Transfer Box (X313), consisting of the four motor
position switches, the ground for the switches and
the drives to move the motor one way or the other.
Motor Position Switches±
pins 17, 32, 33, 7

CIRCUIT OPERATION2
Neutral Switch (X308) or Clutch Switch±
pin 34
A shift between ranges is possible when the
transmission is in neutral. The Transmission
Gearbox Control Unit (Z256) senses this via a
Park/Neutral Switch (X308) on automatic
transmission vehicles and via either a clutch switch
or a lever neutral switch on manual transmission
vehicles. This signal is passed via the BeCM (Z238).
