CIRCUIT OPERATION

When the column switch is in the AUTO position, this function
automatically adjusts the wiping speed of windshield wiper by
detecting the rain fall through lighting control sensor.

.

TECHNICAL DESCRIPTION (COMMENT)

The windshield wiper motor, the column switch, the lighting
control sensor, the harness connector, or the ETACS-ECU may
be defective.

.

TROUBLESHOOTING HINTS

• Defective column switch (column-ECU)

STEP 1. Lighting control sensor installation surface check
Visually check the presence of scratches or air bubbles [(diam-
eter of 5.0 mm(0.2 in) or more] on the windshield to which the
lighting control sensor is installed.
Q: Is the check result normal?

YES : Go to Step 2.
NO : Replace the windshield (Refer to GROUP 42A

−

Windshield Removal and Installation

P.42A-17

).

STEP 2. Windshield wiper operation check
Check that the windshield wipers work normally.
Q: Is the check result normal?

YES : Go to Step 3.
NO : Refer to trouble symptom chart

P.51-32

.

STEP 3. 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, "How to
connect the scan tool (M.U.T.-III)

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 4.

STEP 4. Using scan tool MB991958, read the lighting
control sensor diagnostic trouble code.
Check if a lighting control sensor diagnostic trouble code is set.
Connect the scan tool. Refer to GROUP 54A ETACS, "How to
connect the scan tool (M.U.T.-III)

P.54A-729

."

Q: Is the diagnostic trouble code set?

YES : Diagnose the lighting control sensor. [Diagnostic

Trouble Code: (Refer to GROUP 54A

− Diagnostic

) or Service Data

(

P.51-73

).]

NO : Go to Step 5.

STEP 5. Connector check: D-39 Lighting control sensor
connector
Q: Is the check result normal?

YES : Go to Step 6.
NO : Repair the damaged connector.

STEP 6. Resistance measurement at the D-39 lighting
control sensor connector
(1) Disconnect the connector, and measure the resistance at

the wiring harness.

(2) Measure the resistance between D-39 lighting control

sensor connector terminal No.2 and body ground.

OK: Continuity exists (2

Ω or less)

Q: Is the check result normal?

YES : Go to Step 8.
NO : Go to Step 7.

STEP 7. Check the wiring harness between D-39 lighting
control sensor connector terminal No.2 and body ground.

• Check the ground wires for open circuit.

Q: Is the check result normal?

YES : Intermittent malfunction (Refer to GROUP 00

− How

to Use Troubleshooting/Inspection Service Points -
How to Cope with Intermittent Malfunction

P.00-15

.)

NO : Repair the wiring harness.

STEP 8. Voltage measurement at the D-39 lighting control
sensor connector
(1) Disconnect the connector, and measure the voltage at the

wiring harness side.

(2) Measure the voltage between D-39 lighting control sensor

connector terminal No.1 and body ground.

OK: Battery positive voltage

Q: Is the check result normal?

YES : Go to Step 10.
NO : Go to Step 9.
