HEADLAMP WASHER OPERATION
With the headlamp washer switch in the ON position, the BCM receives input signal requesting. This input sig-
nal is communicated to the IPDM E/R via the CAN communication. The CPU located in the IPDM E/R controls
the headlamp washer relay coil, which when energized, power is supplied
lthrough 10A fuse (No. 38, located in IPDM E/R)
lthrough IPDM E/R terminal 27
lto headlamp washer relay terminals 2 and 5,
lthrough headlamp washer relay terminal 1
lto IPDM E/R terminal 5,
lthrough headlamp washer relay terminal 3
lto headlamp washer motor terminal 1.
Ground is supplied
lto headlamp washer motor terminal 2
lthrough grounds E21, E41 and E61.
With power and ground supplied, headlamp washer operates.

How to Proceed with Trouble Diagnosis
EKS00P6C
1. Confirm the symptoms and customer complaint.
2. Understand operation description and function description. Refer toWW-39, "
System Description".
3. Perform the Preliminary Check. Refer toWW-44, "
Preliminary Check".
4. Check symptom and repair or replace the cause of malfunction.
5. Does headlamp washer operate normally? If YES, GO TO 6. If NO, GO TO 4.
6. INSPECTION END
Preliminary CheckEKS00P6D
CHECK POWER SUPPLY AND GROUND CIRCUIT
1.CHECK FUSES OR FUSIBLE LINK
Check for blown fuses or fusible link.
Refer toWW-41, "Wiring Diagram—HLC—".
OK or NG
OK >> GO TO 2
NG >> If fuse or fusible link is blown, be sure to eliminate cause of malfunction before installing new fuse
or fusible link, Refer toPG-4, "
POWER SUPPLY ROUTING CIRCUIT".
2.CHECK POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM connector.
3. Check voltage between BCM harness connector and ground.
