350Z V6-3.5L (VQ35) (2003)
4. Example (When lighting switch 1st position switch is turned ON)
-
When lighting switch 1st position switch is turned ON, contact in combination switch turns ON. At this time if OUTPUT 5 transistor is
activated, BCM detects current flow in INPUT 4.
-
When OUTPUT 5 transistor is ON, BCM detects current flow in INPUT 4, and judges lighting switch 1st position switch 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 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.
