If the system cannot receive any signal from the col-
umn switch (windshield wiper and washer switch) 
due to a open circuit in the LIN communication line or 
other reasons, the system will enter the fail-safe 
mode when the ignition switch is at the "ACC" posi-
tion.

TROUBLESHOOTING HINTS

• The wiring harness or connectors may have 

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

• The column switch may be defective

• The ETACS-ECU may be defective

• The LIN bus line 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 GROUP 54A ETACS, "Diag-
nostic function 

P.54A-729

."

Q: Is the diagnostic trouble code set?

YES : Diagnose the ETACS-ECU. Refer to GROUP 54A 

ETACS, "Diagnostic trouble code chart 

P.54A-732

."

NO :  Go to Step 2.

STEP 2. Retest the system.
Check that the windshield wipers work normally.
Q: Is the check result normal?

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

Cope with Intermittent Malfunction

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.
