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 ON)

When wiper switch is turned ON, contact in combination switch turns ON. At this time if OUTPUT 1 tran-
sistor is activated, BCM detects that voltage changes in INPUT 3.

When OUTPUT 1 transistor is ON, BCM detects that voltage changes in INPUT 3, and judges that front
wiper low is ON. Then BCM sends front wiper request signal (LO) to IPDM E/R using CAN communica-
tion.

When OUTPUT 1 transistor is activated again, BCM detects that voltage changes in INPUT 3, and recog-
nizes that wiper switch is continuously ON.

Front Wiper Interval Time Is Not Controlled by Vehicle SpeedAKS007A1
1. CHECK FUNCTION OF COMBINATION METER
Confirm that speedometer operates normally.
Does the front wiper operate normally?
YES >> GO TO 2.
NO >> Combination meter vehicle speed system malfunction. GO TO DI-17, "
Vehicle Speed Signal
Inspection" .
2. CHECK CAN COMMUNICATION BETWEEN BCM AND COMBINATION METER
Select “BCM” on CONSULT-II, and perform self-diagnosis for
“BCM”.

NO DTC>>Replace BCM. Refer to BCS-15, "Removal and Installa-
tion of BCM" .
CAN COMM CIRCUIT>>Check CAN communication line of BCM.
GO TO BCS-14, "
CAN Communication Inspection Using
CONSULT-II (Self-Diagnosis)" .
Front Wiper Intermittent Operation Switch Position Cannot Be AdjustedAKS007YW
1. CHECK COMBINATION SWITCH INPUT SIGNAL
Select “BCM” on CONSULT-II. With “WIPER” data monitor, make
sure “INT VOLUME” changes in order from 1 to 7 according to oper-
ation of the intermittent switch dial position.
OK or NG
OK >> Replace BCM. Refer to LT- 11 3 , "Combination Switch
Inspection" .
NG >> Replace wiper switch.
Wipers Do Not Wipe When Front Washer OperatesAKS00575
1. CHECK CIRCUIT BETWEEN COMBINATION SWITCH AND BCM
Select “BCM” on CONSULT-II. With “WIPER” on “DATA MONITOR”,
make sure “FR WASHER SW” turns ON-OFF according to operation
of front washer switch.
OK or NG
OK >> Replace BCM. Refer to BCS-15, "Removal and Installa-
tion of BCM" .
NG >> Replace wiper switch.
