back in the connector.

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

condition?

YES:

 Go to Step 4.

NO:

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

GROUP 00E, Harness Connector Inspection P.00E-2. Verify
that the windshield wiper operates normally when the
windshield wiper switch is moved to each position.

STEP 4. Check the windshield wiper motor.

(1)

Disconnect windshield wiper motor connector A-08.

(2)

Connect a battery to the windshield wiper motor as shown.
Then check if the windshield wiper motor operates normally
at high and low speeds.

Q:Does the windshield wiper motor operate normally?

YES:

 Go to Step 5.

NO:

 Replace the windshield wiper motor. Verify that the

windshield wiper operates normally when the windshield
wiper switch is moved to each position.

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. Verify
that the windshield wiper operates normally when the
windshield wiper switch is moved to each position.

STEP 6. Check the wiring harness between windshield
wiper motor connector A-08 (terminals 1 and 4) and ETACS-
ECU connector C-304 (terminals 5 and 6).

Q:Is  the  wiring  harness  between  windshield  wiper  motor

connector  A-08  (terminals  1  and  4)  and  ETACS-ECU

connector C-304 (terminals 5 and 6) in good condition?

YES:

 No action is necessary and testing is complete.

DIAGNOSIS

NO:

 The wiring harness may be damaged or the connector

(s) may have loose, corroded or damaged terminals, or
terminals pushed back in the connector. Repair the wiring
harness as necessary. Verify that the windshield wiper
operates normally when the windshield wiper switch is
moved to each position.

INSPECTION PROCEDURE 5: The windshield intermittent wiper interval cannot be
adjusted by operating the windshield intermittent wiper volume control switch.

DIAGNOSIS

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  54Ad  ETACS,
"Diagnostic function P.54Ad-5."

Q:Is the diagnostic trouble code set?

YES:

 Diagnose the ETACS-ECU. Refer to GROUP 54Ad ETACS,

"Diagnostic trouble code chart P.54Ad-8."

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.51B-48.

STEP 3. 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.
