Murano AWD V6-3.5L (VQ35) (2003)
NOTE: Dual switches are set for head lamps.
4. Example (When lighting switch 1st position is turned ON)
-
When lighting switch 1st position is turned ON contact in combination switch turns ON. At this time if OUTPUT 5 transistor is activated BCM
detects current flow in INPUT 5.
-
When OUTPUT 4 transistor is ON BCM detects current flow in INPUT 4 and judges lighting switch 1st position is ON. Then BCM sends tail
lamp ON signal to IPDM E/R using CAN communication.
-
When OUTPUT 5 transistor is activated again BCM detects current flow in INPUT 4 and confirms lighting switch 1st position 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.
CAN COMMUNICATION CONTROL
CAN communication is capable of dealing with a lot of information through the two communication lines (CAN L-line CAN H-line) connecting control
