1997 MERCEDES-BENZ ML320 engine

Vehicles with EZS control unit without column sleeve module (MRM)
The signals from the push-button switch for the cruise control are detected by the control unit EIS and
transmitted to the CAN data bus.
Vehicles without EZS control unit
The signals from the cruise control switch are transmitted directly to the engine control unit.
Vehicles with manual transmission (MT)
Cruise control remains active during gear change, in other words the cruise control is not switched off when the
clutch is operated.
Traction systems control unit
Transmits the vehicle speed signal via CAN to the ME control unit.

functionWhen the cruise control push-button switch is operated, two switching contacts are
always activated simultaneously. The actual input takes place by closing one of the
switching contacts (e.g. storing the speed). The safety contact must close simultaneously
so that the input is accepted.

MODEL all
RISK OF INJURY - AS30.30-Z-0001-01A
Never look directly into the laser beam. Do not attempt to suppress the natural reflex of the eyelids.
Avoid direct skin contact with the laser beam. If eye damage is suspected, consult an eye specialist
without delay.

switch positionin footwell behind accelerator pedal
Kickdown
switch taskIdentify kickdown position of accelerator pedal, in order to influence
transmission control, cruise control, variable speed limiter and

Kickdown
switch designUp to approx. 6/02 designed as an electrical switch (S16/6). As of
approx. 7/02 (without engine 166) the electrical switch is replaced by
the Kickdown simulator (spring).GF30.20-P-

Engine 111, 112, 113, 119, 120, 137 up to approx 6/02 and Engine 166:
on closed contact the ground is switched to the engine control unit
As of approx. 7/02 (without Engine 166): Kickdown recognition is
performed via the signal of the accelerator pedal sensor.

Risk of injury!
Class 2 lasers emit a visible radiation. Looking directly into the laser beam can result in damage to the eye.
The reflected laser beam can likewise cause damage to the eye.
For this reason, avoid reflections of the laser beam by using mirrors and similar aids. Laser beams may also
cause skin damage.
Safety instructions/precautions
Never look directly into the laser beam.
Do not attempt to suppress the natural reflex of the eyelids.
The eye is normally protected by defensive reactions including the reflex of the eyelid closing.
Avoid direct skin contact with the laser beam.
If damage to the eye is suspected, consult an eye specialist immediately.
It is prohibited to further bundle the laser beam and thus to concentrate the energy (increasing the laser
class).
Only properly instructed personnel may be entrusted with the work on this equipment.
