Automatic Wipe Mode

In models equipped with the automatic wiper feature, the internal circuitry of both the multi-function switch, the rain sensor, and the CCN work in concert to provide an automatic wiper mode with five sensitivity selections. When selected, this switch position will automatically operate the front wipers at the designated sensitivity setting and maintain visibility through the windshield glass at that predetermined sensitivity setting.

With automatic wipers, when the control knob on the control stalk of the multi-function switch is moved to one of the six Auto sensitivity positions, the SCCM sends an electronic message to the Rain Sensor over the Controller Area Network (CAN) data bus network indicating the selected position. The sensor monitors an area within the wipe pattern of the windshield glass for the accumulation of moisture. Based upon internal programming and the selected sensitivity level, when sufficient moisture has accumulated the rain sensor sends the appropriate electronic wipe command messages to the FCM over the CAN data bus and the FCM operates the front wiper system accordingly.

As the sensitivity level is set higher, the rain sensor is more sensitive to moisture accumulation and will send wipe commands more frequently. The SCCM logic is also programmed to provide an immediate wipe cycle each time the control knob on the multi-function switch is moved from a non-automatic wipe position to one of the sic Auto sensitivity positions, and another immediate wipe cycle each time the control knob is moved from a lower Auto sensitivity position to a higher Auto sensitivity position.
