Murano AWD V6-3.5L (VQ35) (2003)
4. Example (When fog lamp switch is turned ON.)
-
When fog lamp switch is turned ON, contact in combination switch turns ON.At this time if OUTPUT 4 transistor is activated, BCM detects
current flow in INPUT 5.
-
When OUTPUT 4 transistor is ON, BCM detects current flow in INPUT 5, and judges fog lamp switch is ON.Then BCM sends fog lamp ON
signal to IPDM E/R using CAN communication.
-
When OUTPUT 4 transistor is activated again, BCM detects current flow in INPUT 5, and confirms fog lamp switch is continuously ON.
NOTE: Each OUTPUT terminal transistor is activated at 10 ms intervals.Therefore, after a switch is turned ON, the electrical loads are activated
with a time delay, but this time delay is so short that it cannot be noticed.
5. Operation mode
-
Combination switch reading function has operation modes shown.
a. Normal mode
-
When BCM is not in sleep mode, each OUTPUT (1 - 5) terminal turns ON-OFF at 10 ms intervals.
b. Sleep mode
-
When BCM is in sleep mode, transistors of OUTPUT 1 and 2 stop the output, and BCM enters low-current-consumption mode.OUTPUTS
(3 - 5) turn ON-OFF at 60 ms intervals, and receive lighting switch input only.
