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
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
NO : Repair the wiring harness.

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)
."
Q: Is the diagnostic trouble code set?
YES : Diagnose the ETACS-ECU. Refer to GROUP 54A
ETACS, "Diagnostic trouble code chart
."
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)
."
Q: Is the diagnostic trouble code set?
YES : Diagnose the lighting control sensor. [Diagnostic
