interconnected flap shafts are closed by means of vacuum by the intake manifold switchover diaphragm unit.
When the variable intake manifold switchover valve is open, the vacuum is supplied from a vacuum reservoir
with check valve in the intake manifold. The reservoir volume is designed for about 5 operations without
renewed evacuation.
The variable flaps open by means of spring force.

Terminal 61 is used for the generator
indicator lamp. When the ignition is
On
the excitation voltage is applied to it and
the generator voltage when the engine is
running.
However, a terminal is required for some
systems (e.g. exterior lamp indicator) which
D
is exactly at ground potential (low level),
when the engine is not running with the
ignition
On
D
is exactly at least 10.5 V (high level),
when the voltage at terminal 61
exceeds a particular voltage or the
engine speed exceeds a particular
threshold (480 rpm).
Terminal 61e is used for this (engine running
recognition/speed threshold value).
Terminal 61e is produced in instrument
cluster (A1) in accordance with the sketched
circuit diagram:
An electronic system is ...via terminal 15
Terminal 61 and the speed signal are used as input signals which
reach the instrument cluster via the CAN data bus.
If a particular speed or a particular voltage threshold at terminal 61 is
exceeded, the transistor switches off and terminal 61e goes to high
level (terminal 61 and the speed signal are interlinked to terminal 61e
via an OR function. Also refer to table.)
The maximum current at terminal 61e is approx. 2 mA at high level
and approx. 350 mA at low level. The switching delay is
0.5 seconds in each case.
Exterior lamp indicator lamp and charge indicator lamp
The input signal of terminal 61 and the speed signal are used for
engine running recognition. Depending on these input signals the
exterior lamp failure indicator lamp (A1e14) or the generator charge
indicator lamp (A1e5) is actuated (refer to table).
The instrument cluster also passes on the status of terminal 61e as a
CAN message. The information is consequently available to all bus
participants.
On models 163 and 168 terminal 61e is only made available as a
CAN message. There is no discrete terminal 61e line.
