Preliminary CheckAKS0057M
INSPECTION POWER SUPPLY AND GROUND CIRCUIT
Inspection Procedure
1. CHECK FUSE

Check if wiper and washer fusible link and fuse is blown.
Refer to WW-37, "Wiring Diagram — WIP/ R —" .
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 to PG-3, "
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 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.

nals 59 (Y), 70 (SB) and rear wiper motor harness connector
D107 terminals 3 (BR), 4 (SB).
4. Check continuity between BCM harness connector B14 termi-
nals 59 (Y), 70 (SB) and ground.
OK or NG
OK >> GO TO 4.
NG >> Repair harness or connector.
4. CHECK REAR WIPER TO GROUND
Check continuity between rear wiper motor harness connector D107
terminal 2 (B) and ground.
OK or NG
OK >> GO TO 5.
NG >> Repair harness or connector.
5. CHECK BCM
1. Connect BCM connector and rear wiper motor connector.
2. Turn ignition switch ON.
3. With rear wiper switch ON, check voltage between BCM har-
ness connector B14 terminal 59 (Y) and ground.
OK or NG
OK >> Replace rear wiper motor.
NG >> Replace BCM. Refer to BCS-15, "
Removal and Installation of BCM" . 59 (Y) - 3 (BR) : Continuity should exist.
