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)

• Malfunction of the lighting control sensor

• Defective windshield wiper motor

• Malfunction of ETACS-ECU

• Damaged wiring harness and connectors

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 

Trouble Code Chart 

P.54A-127

) 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.
