STEP 6. Measure the voltage at the C-316 ETACS-ECU 
connector.
(1) Disconnect the connector, and measure the voltage at the 

wiring harness side.

(2) Measure the voltage between C-316 ETACS-ECU 

connector terminal No. 1 and body ground.

OK: Battery positive voltage

Q: Is the check result normal?

YES : Replace the Lighting control sensor.
NO :  Go to Step 7.

STEP 7. Check the wiring harness between C-316 
ETACS-ECU connector terminal No.1 and D-39 lighting 
control sensor connector terminal No.3.

• Check the input and output lines for open or short 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.

INSPECTION PROCEDURE 9: Sometimes the rain sensitive AUTO wiper function works even though 
there is no rainfall < Vehicles with lighting control sensor>.

CAUTION

Whenever ECU is replaced, ensure that the input and output signal circuits are normal.

.

TECHNICAL DESCRIPTION (COMMENT)

The lighting control sensor may be defective or a failure in the 
lighting control sensor (rain sensor) adaptation is suspected.

.

TROUBLESHOOTING HINTS

• Malfunction of the lighting control sensor

• Lighting control sensor (rain sensor) adaptation failure

STEP 1. Lighting control sensor (rain 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 Inspection procedure 3 

P.51-41

.

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. [Diagnosis 

Code: (Refer to GROUP 54A 

− Diagnosis Code Chart 

P.54A-127

) or service data (

P.51-73

).]

NO :  Go to Step 5.

STEP 5. Lighting control sensor (rain sensor) installation 
surface check
Check that the lighting control sensor (rain sensor) is installed 
to the windshield glass firmly.
Q: Is the check result normal?

YES : Go to Step 6 after completion of the lighting control 

sensor (rain sensor) adaptation (

P.51-85

).

NO :  Install the lighting control sensor (rain sensor) to the 

windshield glass correctly (Refer to GROUP 54A 

− 

Lighting control sensor removal and Installation 

P.54A-217

).

STEP 6. Retest the system.
Check the lighting control sensor (rain sensor) after completion 
of the lighting control sensor (rain sensor) adaptation
(1) Check that the windshield glass surface is dry.
(2)  Pour the windshield glass surface where the lighting control 

sensor is installed.

Q:  Does the windshield wiper operate?

Operate one or more : Intermittent malfunction (Refer to 

GROUP 00 

− How to Use Troubleshooting/Inspection 

Service Points - How to Cope with Intermittent 
Malfunction 

P.00-15

).

Does not operate :  Troubleshoot the rain sensitive wiper 

function (Refer to Inspection procedure 7 

P.51-55

).
