Concept of auto active test
• IPDM E/R starts the auto active test with the door
switch signals transmitted by BCM via CAN communica-
tion. Therefore, the CAN communication line between IPDM E/R and BCM is considered normal if the auto
active test starts successfully.
• The auto active test facilitates troubleshooting if any systems controlled by IPDM E/R cannot be operated.

CONSULT Function (IPDM E/R)INFOID:0000000009944156
CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentiall y causing a discharged battery and a no-start condition.

FRONT WIPER DOES NOT OPERATE
FRONT WIPER DOES NOT OPERATE
DescriptionINFOID:0000000009464625
The front wiper does not operate under any operation conditions
Diagnosis ProcedureINFOID:0000000009464626
Regarding Wiring Diagram information, refer to WW-23, "Wiring Diagram - With Rear View Camera Washer
Control System".
1. CHECK WIPER RELAY OPERATION
IPDM E/R AUTO ACTIVE TEST
1. Start IPDM E/R auto active test. Refer to PCS-8, "Diagnosis Description"
.
2. Check that the front wiper operates at the LO/HI operation.
CONSULT ACTIVE TEST
1. Select FRONT WIPER of IPDM E/R active test item.
2. While operating the test item, check that front wiper LO/HI operation and OFF.
is the inspection result normal?
YES >> GO TO 5.
NO >> GO TO 2.
2. CHECK FRONT WIPER MOTOR FUSE
1. Turn the ignition switch OFF.
2. Check that the front wiper motor fuse 30A (No. 41, located in the IPDM E/R) is not blown.
Is the fuse blown?
YES >> Replace the fuse after repairing the affected circuit.
NO >> GO TO 3.
3. CHECK FRONT WIPER MOTOR (GND) OPEN CIRCUIT
1. Disconnect front wiper motor.
2. Check continuity between front wiper motor harness connector E25 and ground.
Is the inspection result normal?
YES >> GO TO 4.
NO >> Repair or replace the harness or connectors.
4. CHECK FRONT WIPER MOTOR OUTPUT VOLTAGE
CONSULT ACTIVE TEST
1. Turn the ignition switch ON.
2. Select FRONT WIPER of IPDM E/R active test item.
3. With operating the test item, check volt age between IPDM E/R harness connector E18 and ground.
Lo : Front wiper LO operation
Hi : Front wiper HI operation
Off : Stop the front wiper.
