COMBINATION SWITCH READING FUNCTION
Description

BCM reads combination switch (wiper) status, and controls related systems such as head lamps and wip-
ers, according to the results.

BCM reads information of a maximum of 20 switches by combining five output terminals (OUTPUT 1-5)
and five input terminals (INPUT 1-5).
Operation Description

BCM activates transistors of output terminals (OUTPUT 1-5) periodically and, and allows current to flow in
turn.

If any (1 or more) switches are turned ON, circuit of output terminals (OUTPUT 1-5) and input terminals
(INPUT 1-5) becomes active.

At this time, transistors of output terminals (OUTPUT 1-5) are activated to allow current to flow. When volt-
age of input terminals (INPUT 1-5) corresponding to that switch changes, interface in BCM detects volt-
age change, and BCM determines that switch is ON.
BCM - Operation Table of Combination Switches
BCM reads operation status of combination switch using combinations shown in table below.

Sample Operation: (When Wiper Switch Turned to LOW Position)

When wiper switch is turned to LOW position, front wiper LOW contact in combination switch turns ON. At
this time if OUTPUT 1 transistor is activated, BCM detects that voltage changes in INPUT 3.

When BCM detects that voltage changes in INPUT 3 while OUTPUT 1 transistor is ON, it judges that front
wiper switch is in LOW position. Then BCM sends front wiper request signal (LO) to IPDM E/R using CAN
communication.

If BCM detects that voltage changes in INPUT 3 when OUTPUT 1 transistor is activated again, it recog-
nizes that wiper switch is still in LOW position.
NOTE:
Each OUTPUT terminal transistor is activated at 10 ms intervals. Therefore after switch is turned ON, electri-
cal loads are activated with time delay. But this time delay is so short that it cannot be detected by human
senses.
