SWITCHING INTERIOR LIGHTS ON/OFF AUTOMATICALLY, FUNCTION - GF82.20-P-2010GH
MODEL 163
Automatic actuation of interior lights is triggered by
opening a door,
unlocking vehicle with transmitter key,
switching off ignition within 30 seconds of switching off exterior lighting (terminal 58k)
or
after crash recognition.
When opening a door, the respective rotary tumbler microswitch (S87/2, S87/3, S87/6 or S87/7) is actuated
and a signal for automatic light actuation is sent to All-Activity-Module (AAM, N10)
With crash recognition by ETR control module with airbag (ETR/ AB, N2/2) up to 11.99 or by restraint
systems control module (N2/7) as of 12/99, signal for automatic light actuation is sent to All-Activity-Module
via a separate cable.

ROTARY TUMBLER MICROSWITCHES, LOCATION - GF82.20-P-4105-01GH
The rotary tumbler microswitch is installed in the rotary tumbler.
Left rear rotary tumbler is shown
Fig. 21: Identifying Rotary Tumbler Microswitches, Location

ROTARY TUMBLER MICROSWITCHES, FUNCTION - GF82.20-P-4105-02GH
The contact in the left rear rotary tumbler microswitch (S87/2), the right rear rotary tumbler microswitch
(S87/3), the right front door rotary tumbler microswitch (S87/6), the left front door rotary tumbler microswitch
(S87/7) or the rear door rotary tumbler microswitch (S88/1) is closed when the respective door is closed (rotary
tumbler snapped in place). The status of the switch contact is read by the All Activity Module (AAM)(N10).
The central locking microswitches, which are also installed in the rotary tumbler, indicate whether a door is
locked or unlocked. These microswitches are no longer used as of 31.08.02.

SAFETY SHUTOFF (WSA) - FUNCTION - GF82.30-P-3005GH
MODEL 163 Applicable as of 1.9.00
Safety shutoff
The intermittent wipe function is interrupted when the vehicle comes to a complete stop and at least one of
the front doors is open. Any wipe cycle in progress is completed before wipers come to a halt.
Wiping resumes when both front doors are closed and/or the vehicle is put into motion.
The safety shutoff therefore only operates when the vehicle is at a complete stop. This ensures that the
intermittent wiping feature remains available during driving even if a door jamb switch is defective.
ANTI-LOCK PROTECTION FOR WIPER MOTOR, FUNCTION - GF82.30-P-4008GH
MODEL 163
The all-activity module(AAM) (N10) recognizes that the wiper motor (M6/1) is locked up because of the
absence of signals from the cam switch.
If signals are not recognized for longer than 1 s the front wiper motor relay (F1k17) is no longer actuated.

The anti-lock protection is only effective in the function interval wiping . In other wiper stages the AAM does
not have influence on the wiper motor.
