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. Check the ETACS configuration function.
Use the ETACS configuration function to check that "Front 
wiper operation" is set to "variable INT" or "vehicle speed 
dependent".
Q: Is the check result normal?

YES : Go to Step 3.
NO :  Use the ETACS configuration function to set "Front 

wiper operation" to "variable INT" or "vehicle speed 
dependent". Refer to 

P.51-75

STEP 3. Using scan tool MB991958, check data list. 
Check the input signal related to the windshield wiper opera-
tion.

• Ignition switch: ACC

• Rotate the windshield wiper interval control from (+) to (−) 

side.

OK: Normal condition is displayed.

Q: Is the check result normal?

NO :  Go to Step 4.
YES : Replace the column switch.

STEP 4. Retest the system.
Check that the windshield wiper interval changes when the 
windshield wiper volume control is rotated.
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 6: The windshield intermittent wiper interval is not changed according to 
the vehicle speed.

TECHNICAL DESCRIPTION (COMMENT)

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. 
Alternatively, the vehicle speed-dependent wiper 
may be set to "disabled" by using the configuration 
function.

.

TROUBLESHOOTING HINTS

• The wiring harness or connectors may have 

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

• The combination meter 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. Retest the system.
Check that the windshield intermittent wiper interval can be 
adjusted by operating the windshield intermittent wiper interval 
control switch.
Q: Is the check result normal?

YES : Go to Step 2.
NO :  Refer to Inspection Procedure 5 "The windshield 

intermittent wiper interval cannot be adjusted by 
operating the windshield intermittent wiper interval 
control switch" 

P.51-50

.

STEP 2. Check the ETACS configuration function.
Use the ETACS configuration function to check that "Front 
wiper operation" is set to "Variable INT" or "Speed sensitive".
Q: Is the check result normal?

YES : Go to Step 3.
NO :  Use the ETACS configuration function to set "Front 

wiper operation" to "variable INT" or "Speed 
sensitive". (Refer to 

P.51-75

.)

STEP 3. Using scan tool MB991958, check data list. 
Check the input signal related to the combination meter.

• Drive the vehicle and change vehicle speed.

Q: Is the check result normal?

YES : Go to Step 4.
NO <Normal condition is not displayed for item No. 80.> 
: 

Troubleshoot the speedometer (Refer to GROUP 54A 
− Combination Meter, Diagnosis - Inspection 

Procedure 2: "The speedometer does not work (the 
other meters work)”

P.54A-75

 .)

STEP 4. Retest the system.
Check that the intermittent wiper interval depends on the vehi-
cle speed.
Q: Is the check result normal?

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

Cope with Intermittent Malfunction
