Function sequence for washer nozzle/washer nozzle hose heater

The driver SAM control unit (N10/10) detects the outside temperature via the outside temperature indicator temperature sensor (B14) and transmits this signal to the front passenger SAM control unit (N10/11) via the interior CAN.

At an outside temperature of T < 5 °C, the washer nozzle heater (R2/1) and washer nozzle hose heater (R2/11) are switched on by the front passenger SAM control unit.

If the outside temperature increases to T > 8 °C, the washer nozzle heater and the washer nozzle hose heater are switched off by the front passenger SAM control unit.
