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”.
Displayed self
-diagnosis results
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)" .

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.

After Front Wipers Operate for 10 Seconds, They Stop for 20 Seconds, and after
repeating the operations five times, they become inoperative
AKS007A2
CAUTION:
When auto-stop signal has not varied for 10 seconds or longer while IPDM E/R is operating front
wipers, IPDM E/R considers that front wipers are locked, and stops wiper output. That causes this
symptom.
This status can be checked by “DATA MONITOR” of “IPDM E/R” on which “WIPER PROTECTION”
item shows “BLOCK”.
1. CHECK CIRCUIT BETWEEN IPDM E/R AND WIPER MOTOR (1)
With CONSULT-ll
Select “IPDM E/R” on CONSULT-II. With “DATA MONITOR”, confirm
that “WIP AUTO STOP” turns “ACT P” - “STOP P” linked with wiper
operation.
Without CONSULT-ll
GO TO 2.
OK or NG
OK >> Replace IPDM E/R.
NG >> GO TO 2.
2. CHECK CIRCUIT BETWEEN IPDM E/R AND WIPER MOTOR (2)
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R connector and front wiper motor connec-
tor.
3. Check continuity between IPDM E/R harness connector E7 ter-
minal 32 (L) and front wiper motor harness connector E57 termi-
nal 5 (L).
4. Check continuity between IPDM E/R harness connector E7 ter-
minal 32 (L) and ground.
OK or NG
OK >> GO TO 3.
NG >> Repair harness or connector.
SKIA5301E
32 (L) - 5 (L) : Continuity should exist.
32 (L) - Ground : Continuity should not exist.

3. CHECK CIRCUIT BETWEEN IPDM E/R AND WIPER MOTOR (3)
1. Connect IPDM E/R connector and front wiper connector.
2. Turn ignition switch ON.
3. Check voltage between IPDM E/R harness connector E7 termi-
nal 32 (L) and ground while front wiper motor is stopped and
while it is operating.
OK or NG
OK >> Replace IPDM E/R.
NG >> Replace front wiper motor.
Front Wipers Do Not StopAKS007A3
1. CHECK CIRCUIT BETWEEN COMBINATION SWITCH AND BCM
With CONSULT-ll
Select “BCM” on CONSULT-II. With “WIPER” on “DATA MONITOR”,
confirm that “FRONT WIPER INT”, “FRONT WIPER LOW”, “FRONT
WIPER HI”, and “FRONT WASHER SW” turn ON-OFF according to
wiper switch operation.
Without CONSULT-ll
Refer to LT- 11 3 , "
Combination Switch Inspection" .
OK or NG
OK >> Replace IPDM E/R.
NG >> Check wiper Switch. Refer to LT- 11 3 , "
Combination
Switch Inspection" .
