FRONT WIPER AND WASHER SYSTEM WW-7 C D E F G H I J L M A B WW Revision: 2006 August 2006 Murano MIST OPERATION When the wiper switch is turned to the mist position, wiper low speed operation cycles once and then stops. If the switch is held in the mist position, low speed operation continues. FAIL-SAFE FUNCTION If an abnormality occurs in CAN communications, IPDM E/R holds the condition just before fail-safe status is COMBINATION SWITCH READING FUNCTION ● BCM reads combination switch (wiper) status, and controls related systems such as head lamps and wip- ● BCM reads information of a maximum of 20 switches by combining five output terminals (OUTPUT 1-5) Operation Description ● BCM activates transistors of output terminals (OUTPUT 1-5) periodically and, and allows current to flow in ● If any (1 or more) switches are turned ON, circuit of output terminals (OUTPUT 1-5) and input terminals ● At this time, transistors of output terminals (OUTPUT 1-5) are activated to allow current to flow.
