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.

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.

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.
