CIRCUIT OPERATION

• The sunroof motor assembly is energized

through fusible link (34) by the battery.

• When the ignition switch (IG1) signal is on, the

sunroof motor assembly is ready to operate.

.

TROUBLESHOOTING HINTS

• The sunroof switch may be defective

• The sunroof motor assembly may be defective

• The wiring harness or connectors may have

loose, corroded, or damaged terminals, or termi-
nals pushed back in the connector

DIAGNOSTIC PROCEDURE

Required Special Tools:

• MB992006: Extra fine probe

• MB991223: Harness set

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

• MB991824: Vehicles Communication Interface (V.C.I.)

• MB991827: M.U.T.-III USB Cable

• MB991910: M.U.T.-III Main Harness A (Vehicles with

CAN communication system)

STEP 1. Using scan tool MB991958, read the diagnostic
trouble code.

CAUTION

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958. Refer to GROUP 42B, "How

to connect scan tool (M.U.T.-III)

P.42B-13

."

(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.42A-180

.

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 GROUP 00E, Harness Connector Inspection

P.00E-2

. Check that the sunroof works normally.

STEP 3. Sunroof switch check
(1) Remove the sunroof switch. Refer to

P.42A-217

.

(2) Check continuity when the sunroof switch is operated to

"OPEN", "TILT-UP" or "CLOSE/TILT-DOWN" position.

Q: Is the sunroof switch normal?

YES : Go to Step 4.
NO : Replace the sunroof switch. Check that the sunroof

works normally.

STEP 4. Check the ground circuit to the sunroof motor
assembly. Measure the resistance at sunroof switch
connector D-03.
(1) Disconnect sunroof switch connector D-03 and measure the

resistance available at the wiring harness side of the
connector.

(2) Measure the resistance value between terminal 4 and

ground.

• The resistance should be 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 7.
NO : Go to Step 5.

STEP 5. Check sunroof motor assembly connector D-04
for loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is sunroof motor assembly connector D-04 in good

condition?
YES : Go to Step 6.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection
