REAR WIPER AND WASHER SYSTEM
Revision: 2004 November 2004 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 wiper switch is in rear wiper INT position, BCM detects rear wiper INT signal by BCM wiper switch read-
ing 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 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 rear washer motor terminal 2
through combination switch (wiper switch) terminal 13
to combination switch (wiper switch) terminal 12
through grounds M35, M45 and M85.
With ground supplied, rear washer motor is operated.
When BCM detects that rear washer motor has operated for. 0.4 seconds or linger, BCM operates rear wiper
motor low speed.
When 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.

2. CHECK POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM connector.
3. Check voltage between BCM harness connector terminal and
ground.
OK or NG
OK >> GO TO 3.
NG >> Check harness for open or short between fuse, fusible link and BCM.
3. CHECK GROUND CIRCUIT
Check continuity between BCM harness connector M4 terminal 49
(B), 52 (B) and ground.
OK or NG
OK >> INSPECTION END
NG >> Repair harness or connector.
CONSULT-II FunctionsAKS007AG
CONSULT-II can display each diagnostic item using the following diagnostic test modes: work support, self-
diagnostic results, data monitor and active test through data reception and command transmission via the
BCM CAN communication line.
CONSULT-II OPERATION
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. With the ignition switch OFF, connect CONSULT-II and CON-
SULT-II CONVERTER to the data link connector, then turn the
ignition switch ON.
