To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before
connecting or disconnecting scan tool MB991958.

(1)

Connect scan tool MB991958. Refer to GROUP 54Ad, "How
to connect scan tool (M.U.T.-III) P.54Af-4."

(2)

Turn the ignition switch to the "ON" position.

(3)

Check whether the ETACS-ECU related DTC is set.

(4)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is the DTC set?

YES:

Diagnose the ETACS-ECU. Refer to P.42Ad-4.

NO:

Go to Step 2.

STEP 2. Check sunroof switch connector D-03 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.

Q:Is sunroof switch connector D-03 in good condition?

YES:

Go to Step 3.

NO:

Repair or replace the damaged component(s). Refer to

that the sunroof works normally.

STEP 6. Check the wiring harness between sunroof switch
connector D-03 (terminal No. 4) and sunroof motor
assembly connector D-04 (terminal No. 1).

Q:Is the wiring harness between sunroof switch connector

D-03 (terminal 4) and sunroof motor assembly connector

D-04 (terminal No. 1) in good condition?

YES:

No action is necessary and testing is complete.

NO:

The wiring harness may be damaged or the connector

(s) may have loose, corroded or damaged terminals, or
terminals pushed back in the connector. Repair the wiring
harness as necessary. Check that the sunroof works
normally.

STEP 7. Check sunroof motor assembly connector D-04 for
loose, corroded or damaged terminals, or terminals pushed
back in the connector.
