STEP 1. Check the remote controlled mirror switch.
STEP 2. Check the remote controlled mirror switch connector F-12 for loose, corroded or damaged terminals, or terminals pushed back in the connector.
STEP 3. Measure the resistance at the F-12 remote controlled mirror switch connector.
(1) Disconnect the connector, and measure the resistance at the wiring harness-side connector.
(2) Measure the resistance between F-12 remote controlled mirror switch connector terminal No. 1 and body ground.OK: The measured value should be continuity exists (2 ohms or less).
Is the check result normal?
Go to Step 5. Go to Step 4.
STEP 4. Check the wiring harness between F-12 remote controlled mirror switch connector terminal No. 1 and body ground.
STEP 5. Check the ETACS-ECU connector C-411 for loose, corroded or damaged terminals, or terminals pushed back in the connector.
STEP 6. Check the wiring harness between C-411 ETACS-ECU connector terminal No. 24 and F-12 remote controlled mirror switch connector terminal No. 4.
STEP 7. Using scan tool MB991958, check data list.
(1) caution | To prevent damage to scan tool MB991958, always turn the ignition switch to the "LOCK" (OFF) position before connecting or disconnecting scan tool MB991958. |
Connect scan tool MB991958. Refer to "How to connect the Scan Tool (M.U.T.-III)
."
(2) Turn the ignition switch to the "ON" position.
(3) Check the input signals from the remote controlled mirror switch (fold switch).- During the folding/unfolding switch is being pressed.

OK: Normal condition is displayed.
Is the check result normal?
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to use Troubleshooting/inspection Service Points - How to Cope with Intermittent Malfunction ). Replace the ETACS-ECU.
