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.
(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-12

. 

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 3, 2).

• 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 3, 2) 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-12

STEP 7. Retest the system.
Check that the windshield wipers stops at the specified park 
position.
Q: Is the check result normal?

YES : Intermittent malfunction. Refer to GROUP 00, How to 

Cope with Intermittent Malfunction 

P.00-15

. 

NO :  Replace the ETACS-ECU.

INSPECTION PROCEDURE 4: Windshield Wipers do not work normally.

TECHNICAL DESCRIPTION (COMMENT)

If either of the windshield wiper switch positions is 
defective, the windshield wiper motor, column switch 
(windshield wiper and washer switch) or the 
ETACS-ECU may be defective.

.

TROUBLESHOOTING HINTS

• Trouble in input signal system

• The wiring harness or connectors may have 

loose, corroded, or damaged terminals, or termi-
nals pushed back in the connector

• The wiper motor may be defective

• The column switch may be defective

• The ETACS-ECU may be defective

DIAGNOSIS

Required Special Tools:

• MB991223: Harness Set

• MB992006: Extra Fine Probe

• MB991958: Scan Tool (M.U.T.-III Sub Assembly)

• MB991824: V.C.I.

• MB991827: M.U.T.-III USB Cable

• MB991910: M.U.T.-III Main Harness A

STEP 1. Use the scan tool MB991958 to check if an 
ETACS-related diagnostic trouble code is set. 
Connect the scan tool. Refer to "How to connect the scan tool 
(M.U.T.-III) 

P.54B-4

."

Q: Is the diagnostic trouble code set?

YES : Diagnose the ETACS-ECU. Refer to Diagnostic 

trouble code chart 

P.54A-732

."

NO :  Go to Step 2.

STEP 2. Using scan tool MB991958, check data list. 
Check the input signal related to the windshield wiper opera-
tion.

• Ignition switch: ACC

• Operate the windshield wiper switch at each switch posi-

tion.

OK: Normal condition is displayed.

Q: Is the check result normal?

YES : Go to Step 3.
NO :  Troubleshoot the ETACS-ECU. Refer to ETACS, 

Diagnosis - Inspection Procedure 12 "ETACS-ECU 
does not receive any signal from the column switch 
signal." 

P.54A-785

.

STEP 3. Check that the windshield wipers work.
Check that the windshield wipers work at high speed and the 
mist mode.
Q: Is the check result normal?

YES : Go to Step 4.
NO :  Go to Step 10.

STEP 4. 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 5.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. Verify that the windshield wiper operates
