REAR WIPER AND WASHER SYSTEM
Revision: 2006 December 2006 FX35/FX45

through BCM terminal 70

to rear wiper motor 4.
Ground is supplied

to rear wiper motor terminal 2

through grounds B15 and B45.
With power and ground supplied, the rear wiper operates.
INTERMITTENT OPERATION
The rear wiper motor operates the wiper arms at low speed approximately every 7 seconds.
When the wiper switch is in rear wiper INT position, BCM detects rear wiper INT signal by BCM wiper switch
reading function (Refer to BCS-3, "
COMBINATION SWITCH READING FUNCTION" ).
BCM operates rear wiper motor, power supplied

through BCM terminal 70

to rear wiper motor terminal 4.
Ground is supplied

to rear wiper motor terminal 2

through grounds B15 and B45.
With power and ground supplied, rear wiper operates at intermittent.
AUTO STOP OPERATION
With rear wiper switch turned OFF, rear wiper motor will continue to operate until wiper arm reaches rear wiper
stopper.
Then wiper motor turns the other way and wiper arm moves once until wiper arm reaches stopper.
WASHER OPERATION
When the wiper switch is in rear wiper washer position, BCM detects rear wiper washer signal by BCM wiper
switch reading function (Refer to BCS-3, "
COMBINATION SWITCH READING FUNCTION" ), and combina-
tion switch (wiper switch) ground is supplied

to combination switch terminal 11

through front and rear washer pump terminal 2

to front and rear washer pump terminal 1

through combination switch terminal 13

through combination switch terminal 12

through grounds M35, M45 and M85.
With ground supplied, front and rear washer pump is operated.
When the BCM detects that washer pump has operated for. 0.4 seconds or linger, BCM operates rear wiper
pump low speed.
When the BCM detects washer switch is OFF, low speed operation cycles approximately 3 times and then
stops.
BCM WIPER SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" in BODY CONTROL SYSTEM.

Terminals and Reference Values for BCMNKS00336
CAUTION:

Check combination switch system terminal waveform under the loaded condition with lighting
switch, turn signal switch and wiper switch OFF not to be fluctuated by overloaded.

Turn wiper dial position to 4 except when checking waveform or voltage of wiper dial position.
Wiper dial position can be confirmed on CONSULT-II. Refer to LT- 11 9 , "

2. CHECK REAR WIPER AUTO STOP CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM connector and rear wiper motor connector.
3. Check continuity between BCM harness connector B14 terminal 59 and rear wiper motor harness connector D107 terminal 3.
4. Check continuity between BCM harness connector B14 terminal 59 and ground.
5. Check continuity between rear wiper motor harness connector D107 terminal 2 and ground.
OK or NG
OK >> GO TO 3.
NG >> Repair harness or connector.
3. CHECK REAR WIPER MOTOR SIGNAL
1. Connect BCM connector and rear wiper motor connector.
2. Turn ignition switch ON.
3. Check voltage between rear wiper motor harness connector ter- minal and ground while rear wiper motor is stopped and while it
is operating.
OK or NG
OK >> Replace BCM. Refer to BCS-15, "Removal and Installation of BCM" .
NG >> Replace rear wiper motor.
