Washer nozzle and washer nozzle hose heater function
The heated windshield washer nozzle (R2/1) and washer nozzle hose heater (R2/11) are switched on automatically when:

 C. 61 ON (engine: ON) and

 outdoor temperature less than 5°C

is recognized.

Switch-off is accomplished:

 C.61 OUT (engine: OFF) or

 outdoor temperature greater than 7°C

are recognized.

 If the values (outdoor temperature, c.61) are not present or not logical the heater elements are not switched on!

Control of heater elements
The heater elements for the heated windshield washer nozzle (R2/1) and washer nozzle hose heater (R2/11) are connected in parallel.
Control of the heated windshield washer nozzles (R2/1) and washer nozzle hose heater (R2/11) is accomplished directly from the right front SAM control module (N10/7). For this purpose the SAM completes circuit 30 to the heater elements.

Required data

 The ambient temperature is recorded by the ambient temperature display temperature sensor (B14). The left front SAM control module (N10/6) reads in the sensor and sends the measured value as a message on the CAN (interior).

 The status of c.61 (generator G2) is read in directly by the right front SAM control module (N10/7).
