Mitsubishi Outlander XL. Manual - part 847

 

 

TECHNICAL DESCRIPTION (COMMENT)
If the windshield wipers do not stop at predetermined
park  position,  the  windshield  wiper  motor  or  the
ETACS-ECU may be defective.

TROUBLESHOOTING HINTS

The wiring harness or connectors may have loose,
corroded,  or  damaged  terminals,  or  terminals
pushed back in the connector

The windshield wiper motor may be defective

The ETACS-ECU may be defective

DIAGNOSIS

Required Special Tools:

MB991223: Harness Set

MB992006: Extra Fine Probe

STEP1. Check windshield wiper motor connector A-08 for
loose, corroded or damaged terminals, or terminals pushed
back in the connector.

Q:Is  windshield  wiper  motor  connector  A-08  in  good

condition?

YES:

 Go to Step 2.

NO:

 Repair or replace the damaged component(s). Refer to

GROUP 00E, Harness Connector Inspection P.00E-2. Verify
that the windshield wiper works normally.

STEP 2. Check the windshield wiper motor.

(1)

Disconnect windshield wiper motor connector A-08.

(2)

Connect  the  vehicle  battery  to  the  windshield  wiper  motor
connector as shown, and operate the windshield wiper at low
speed. While the windshield wiper is working, disconnect the
battery at positions other than the specified park position to
stop the windshield wiper motor.

(3)

When the battery is connected as shown, the motor should
run at low speed, and then stop at the specified park position.

Q:Does the windshield wiper motor operate normally?

YES:

 Go to Step 3.

NO:

 Replace the windshield wiper motor. The windshield

wiper should now stop at the specified park position.

DIAGNOSIS

STEP 3. Check the fusible link (34) circuit to the windshield
wiper motor. Measure the voltage at windshield wiper motor
connector A-08.

(1)

Disconnect  windshield  wiper  motor  connector  A-08  and
measure the voltage available at the wiring harness side of
the connector.

(2)

Turn the ignition switch to the "ACC" position.

ZC6033620001

Harness side: A-08

(3)

Measure the voltage between terminal 2 and ground.

The  voltage  should  measure  approximately  12  volts
(battery positive voltage).

Q:Is the measured voltage approximately 12 volts (battery

positive voltage)?

YES:

 Go to Step 5.

NO:

 Go to Step 4.

STEP 4. Check the wiring harness between windshield
wiper motor connector A-08 (terminal 2) and the fusible link
(34).

Check the power supply line for open circuits.

Q:Is  the  wiring  harness  between  windshield  wiper  motor

connector  A-08  (terminal  2)  and  the  fusible  link  (34)  in

good condition?

YES:

 Intermittent malfunction. Refer to GROUP 00, How to

cope with intermittent malfunction P.00-15.

NO:

 Repair or replace the damaged component(s). Refer to

GROUP 00E, Cables and wire check P.00E-13.

STEP 5. Check ETACS-ECU connector C-304 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.

Q:Is ETACS-ECU connector C-304 in good condition?

YES:

 Go to Step 6.

NO:

 Repair or replace the damaged component(s). Refer to

GROUP 00E, Harness Connector Inspection P.00E-2.

STEP 6. Check the wiring harness between ETACS-ECU
connector C-304 (terminals 8, 12) and windshield wiper
motor connector A-08 (terminals 2, 3).

Check the output lines for open or short circuits.

Q:Is  the  wiring  harness  between  ETACS-ECU  connector

C-304  (terminals  8,  12)  and  windshield  wiper  motor

connector A-08 (terminals 2, 3) in good condition?

YES:

 Go to Step 7.

NO:

 Repair or replace the damaged component(s). Refer to

GROUP 00E, Cables and wire check P.00E-13.

STEP 7. Retest the system.
Check  that  the  windshield  wipers  stops  at  the  specified  park
position.
