STEP 9. Check the wiring harness between D-39 lighting 
control sensor connector terminal No.1 and fusible link 
(36).
NOTE: Prior to the wiring harness inspection, check intermedi-
ate connector C-36, ETACS-ECU connectors C-307 and 
C-317, and repair if necessary.

• Check the power supply line 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 10. Connector check: C-316 ETACS-ECU connector
Q: Is the check result normal?

YES : Go to Step 11.
NO :  Repair the damaged connector.

STEP 11. 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 12.

STEP 12. 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.

TECHNICAL DESCRIPTION (COMMENT)

The lighting control sensor, the harness connector, or the 
ETACS-ECU may be defective.

.

TROUBLESHOOTING HINTS

• Malfunction of the lighting control sensor

• Malfunction of ETACS-ECU

• Damaged wiring harness and connectors

DIAGNOSIS

Required Special Tools:

• MB991223: Harness Set

• MB992006: Extra Fine Probe

• MB991958: Scan Tool (M.U.T.-III Sub Assembly)

• MB991824: V.C.I.

• MB991827: M.U.T.-III USB Cable

• MB991910: M.U.T.-III Main Harness A

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 Inspection procedure 3

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
