REAR INTERMITTENT WIPE - FUNCTION - GF82.30-P-3001GH 

MODEL 163 Applicable to 31.8.00  

The rear intermittent wipe function is activated by placing the rear wiper/washer switch (S78) in the up 
position. With the switch in this position, the All Activity Module (AAM) (N10) activates the tailgate wiper 
motor (M6/4)
 every five seconds. 

A relay circuit in the wiper motor stops the wiper arm in the park position. 

REAR INTERMITTENT WIPE - FUNCTION - GF82.30-P-3001GK 

MODEL 163 Applicable as of 1.9.00  

The rear intermittent wipe function is linked, among other things, to the operation of the windshield wiper 
system. It will therefore be described in relation to the position of the combination switch (S4): 

Combination switch (S4) position: OFF  

The rear wiper is powered from KI. 15R: ON by operating the rear wiper/washer switch (S78) . Switching 
on the wiper illuminates the LED on the rear wiper/washer switch (S78) and immediately causes the wiper arm 
to perform one complete sweep before switching to intermittent wiping. 

When the vehicle is traveling at speeds of 

less than 100 km/h the wipe interval is 10 seconds  

of 100 km/h or more the wipe interval is 5 seconds .  

The wiper is turned off by reactivating the wiper/washer switch. 

Combination switch (S4) position: Wiper speed 1 or 2  

The rear wiper is activated from KI. 15R: ON using the rear wiper/washer switch (S78) . 

Switching on the wiper illuminates the LED on the rear wiper/ washer switch (S78) and immediately 
causes the wiper arm to perform one complete sweep before switching to intermittent wiping. The wipe 
interval is 5 seconds .

The wiper is turned off by reactivating the wiper/washer switch.

The rear wiper switches on automatically from KI. 15R: ON when reverse gear is engaged. The wiper 
operates continuously without delays until reverse gear is disengaged. Note: The LED on the rear 
wiper/washer switch (S78) does not illuminate when vehicle is in reverse gear.  

Combination switch (S4) position: Intermittent  

When the combination switch (S4) is in the Intermittent position we must differentiate between vehicles 
with and without rain sensors (code 345a) when describing the rear wiper function. 

No rain sensor (no code 345a)  

The rear intermittent wipe function is activated as follows: 

By engaging reverse gear ; from KI. 15: ON . The wiper arm immediately performs one complete 
sweep. 

Then the rear wiper switches to intermittent wiping at a frequency half that of the front windshield 
wiper
 until the vehicle is put into neutral or another gear. 

By activating the rear wiper/washer switch (S78) ; from KI. 15R: ON . Switching on the wiper 
illuminates the LED on the rear wiper/washer switch (S78) and immediately causes the wiper arm to 
perform one complete sweep. Then the rear wiper switches to intermittent wiping at a frequency half 
that of the front windshield wiper. The wiper is turned off by reactivating the wiper/washer switch 

The start of each wipe cycle is synchronized with the front wiper system. 

With rain sensor (with code 345a)  

The rear intermittent wipe function is activated as follows: 

By engaging reverse gear ; from KI. 15: ON . The wiper arm immediately performs one complete 
sweep. Then the rear wiper switches to intermittent wiping at a frequency equal to that of the front 
windshield wiper
 until the vehicle is put into neutral or another gear. 

By activating the rear wiper/washer switch (S78) ; from KI. 15: ON. Switching on the wiper 
illuminates the LED on the rear wiper/washer switch (S78) and immediately causes the wiper arm to 
perform one complete sweep before switching to intermittent wiping. The frequency is linked to the 
frequency of the front windshield wiper and is thus controlled by the rain (B38)sensor . 

NOTE:

The LED on the rear wiper/washer switch (S78) does not illuminate when 
the vehicle is in reverse gear.

NOTE:

The LED on the rear wiper/washer switch (S78) does not illuminate when 
the vehicle is in reverse gear.
