REAR WASH - FUNCTION - GF82.35-P-3001GH
MODEL 163
The rear wash function is activated by placing the rear wiper/ washer switch (S78) in the down position. The
switch contact connects the tailgate washer pump (M5/3) to terminal 15. The All Activity Module (AAM)
(N10) detects the activation of the switch via the second switch contact and actuates the tailgate washer motor
(M6/4) and the tailgate washer fluid pump (M5/3) for as long as the switch is on.
The activation time for the tailgate washer fluid pump (M5/3)is limited to 15 sec. To reactivate the pump, the
button must be pressed again.
To wipe window dry, the tailgate wiper motor (M6/4) remains activated for five seconds after the switch is
released.

As described for the rear wiper function, a relay circuit in the wiper motor stops the wiper in the park position .
WINDSHIELD WASH - FUNCTION - GF82.35-P-3002GH
MODEL 163
The windshield wash function is activated by pulling the combination switch, washer switch (S4s4) towards
the steering column. The switch contact connects the washer pump (M5/1) to terminal 15R. The All Activity
Module (AAM) (N10) detects switch activation via an input that measures power supply to the washer pump
(M5/1).
If the combination switch (S4) is in the Wiper Off or Intermittent position, the AAM activates the wiper
motor (M6/1) via rela
y F1k17 . To wipe windshield dry, the motor continues to operate after the switch has

4-channel power amplifier for vehicle loudspeakers
System interlinkage
The radio and navigation unit (A2/56) is provided with the following components for data exchange with
external digital components:
CAN (A1 -A2/56)
The radio and navigation unit (A2/56) is connected with the instrument cluster (A1) via a separate
CAN bus. The difference to the other CAN systems is indicated by the spelling CAN bus (A1-A2/56).
The CAN bus (A1-A2/56) allows the following functions:
Operation of the radio and navigation unit (A2/56)is also possible with the multifunction steering
wheel.
The multifunction display (A1/p13) in the instrument cluster (A1) can display navigation
information on the current operating status of the radio and navigation unit (A2/56) .
The connection to the CAN bus (A1-A2/56) is only realized on models 208 and 210. (Status 3/99)
Digital data bus (D2B)
Data can be exchanged between the external audio components, the telephone system and - if present -
the voice control system over the D2B bus. This allows control data as well as the actual audio signals
(e.g. music from CD changer) to be transferred.
The only additional D2B component presently possible is the CD changer (A2/6) (Status: 3/99)
K bus (diagnostic interface)
Data exchange is accomplished between the diagnostic interface and the hand-held tester (reading out
DTCs and actual values, ...).
The communication between the HHT and all other D2B components is accomplished over the radio
and navigation unit (A2/56) diagnostic interface.
