Mitsubishi Outlander (2003+). Manual — part 472

SYMPTOM PROCEDURES

SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR

54B-177

NOTE:

Prior to the wiring harness inspection, check the
intermediate connector A-14, and repair if necessary.

•

Check the power supply line to front-ECU for
open circuit.

Q: Is the check result normal?

YES :

Go to Step 14.

NO :

Replace the front-ECU.

Step 14. Retest the system.

Check that the windshield wipers work normally by
moving the switch to each position.

Q: Is the check result normal?

YES :

The trouble can be an intermittent

malfunction (Refer to GROUP 00

−

How to

Cope with Intermittent Malfunction

P.00-6

).

NO :

Replace the windshield wiper motor.

INSPECTION PROCEDURE F-5: The intermittent wiper interval can not be adjusted by operating the
windshield intermittent wiper volume control.

CAUTION

Whenever the ECU is replaced, ensure that the
input and output signal circuits are normal.

COMMENTS ON TROUBLE SYMPTOM
The column switch or the front-ECU may be
defective.

POSSIBLE CAUSES

•

Malfunction of the column switch

•

Malfunction of the front-ECU

•

Damaged harness wires and connectors

DIAGNOSIS PROCEDURE

Step 1. Pulse check

Check the input signals below which are related to
the windshield intermittent wiper function.

OK: The MUT-II/III sounds or the voltmeter
needle fluctuates.

Q: Is the check result normal?

All the signals are received normally. :

Go to Step

2.

The ignition switch (IG1) signal is not received. :

Refer to inspection procedure N-1 "The
ignition switch (ACC) signal is not received

P.54B-298

."

The windshield wiper volume signal is not
received. :

Refer to inspection procedure N-7 "The

windshield wiper volume signal is not
received

P.54B-321

."

Step 2. Retest the system.

Check that the windshield intermittent wiper interval
can be adjusted by operating the windshield
intermittent wiper volume control.

OK: The intermittent wiper interval is
changed as the intermittent wiper volume is
rotated.

Q: Is the check result normal?

YES :

The trouble can be an intermittent

malfunction (Refer to GROUP 00

−

Cope with Intermittent Malfunction

P.00-6

).

NO :

Replace the front-ECU

INSPECTION PROCEDURE F-6: The intermittent wiper interval is not changed according to the
vehicle speed.

CAUTION

Whenever the ECU is replaced, ensure that the
input and output signal circuits are normal.

COMMENTS ON TROUBLE SYMPTOM
The ETACS-ECU calculates the intermittent wiper
interval according to the vehicle speed signal which
is sent by the engine-ECU.
If the intermittent wiper interval does not depend on
the vehicle speed, the input circuit of the vehicle
speed signal and the ETACS-ECU may be defective.

POSSIBLE CAUSES

•

Malfunction of the vehicle speed signal
(engine-ECU)

•

Malfunction of the ETACS-ECU

•

Damaged harness wires and connectors

DIAGNOSIS PROCEDURE

Step 1. Retest the system.

Check that the windshield intermittent wiper interval
can be adjusted by operating the windshield
intermittent wiper volume control.

Q: Is the check result normal?

YES :

Go to Step 2.

NO :

Refer to Inspection Procedure F-5 "The
intermittent wiper interval can not be
adjusted by operating the windshield
intermittent wiper volume control

P.54B-178

."

Step 2. Pulse check

Check the input signals below which are related to
the vehicle speed-dependent intermittent wiper.

OK: The MUT-II/III sounds or the voltmeter
needle fluctuates.

Q: Is the check result normal?

All the signals are received normally. :

Go to Step

3.

The ignition switch (IG1) signal is not received. :

Refer to inspection procedure N-1 "The
ignition switch (ACC) signal is not received

P.54B-298

The vehicle speed signal (engine-ECU) is not
received. :

Step 3. Check the SWS monitor customized
function.

Use the SWS monitor customize function to confirm
that "SPEED SEN WIP" is set to "W.FUNCTION".

CAUTION

The SWS monitor must be used in order to
confirm and change that setting. Use the SWS
monitor to confirm and/or change the
customized function.

Q: Is the check result normal?

YES :

Go to Step 4.

NO :

Use the SWS monitor customize function to
set the "SPEED SEN WIP" to
"W.FUNCTION" (Refer to GROUP 54B

−

Customize adjustment

P.54B-393

).

Step 4. Retest the system.

Check that the intermittent wiper interval depends on
the vehicle speed.

Q: Is the check result normal?

YES :

The trouble can be an intermittent

malfunction (Refer to GROUP 00

).

NO :

Replace the ETACS-ECU.
