Rear Wiper and Washer
Description
The vehicle is equipped with a Rear Wiper and Washer, locally controlled (manual operation) by a Rear MF switch (RMS) connected to the IPM
module. This functionality is directly accessible to the driver. It consists in the possibility to activate or deactivate the wiper of the rear glass. When the
driver decides to activate the rear wiper, he has to choose between several modes of operation using the rear MF switch (RMS):
-
Continuous low speed
-
Rear washer switch
The rear wiper uses a bi-directional motor with integrated logic for rotation sense change, the RAM module manages the wiping period (intermittent or
low speed) and park operation.
Another switch is also used for the rear washer. It consists in activating the front washer pump, located under hood and connected to the FAM module.
The rear washer activation has a consequence on the activation of the rear wiper in order to clean the rear glass.
The driver can be informed of the low level of washer fluid by an indication on the cluster panel.
