BCS-4
BCM (BODY CONTROL MODULE)
Revision: 2004 November 2004 FX35/FX45

BCM reads operation status of combination switch using combinations shown in table below.
NOTE:
Headlamp has a dual system switch.
4. Sample operation: (When lighting switch 1st position turned ON)

When lighting switch 1st position is turned ON, contact in combination switch turns ON. At this time if
OUTPUT 4 transistor is activated, BCM detects that voltage changes in INPUT 5.

When OUTPUT 4 transistor is ON, BCM detects that voltage changes in INPUT 5, and judges that light-
ing switch 1st position is ON. Then BCM sends tail lamp ON signal to IPDM E/R using CAN communi-
cation.

When OUTPUT 4 transistor is activated again, BCM detects that voltage changes in INPUT 5, and rec-
ognizes that lighting switch 1st position is continuously ON.
