CIRCUIT OPERATION

• The sunroof motor assembly is energized

through fusible link (5) by the battery.

• When the ignition switch (IG2) 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

DIAGNOSIS

Required Special Tool:

• MB991223: Test Harness Set

STEP 1. 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 2.
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 2. Check the fusible link (5) line of power supply
circuit to the sunroof motor assembly. Measure the voltage
at sunroof motor assembly connector D-04.
(1) Disconnect sunroof motor assembly connector D-04 and

measure the voltage available at the wiring harness side of
the connector.

(2) Measure the voltage between terminal 1 and ground.

• The voltage should measure approximately 12 volts

(battery positive voltage).

Q: Is the measured voltage approximately 12 volts (battery

positive voltage)?
YES : Go to Step 4.
NO : Go to Step 3.

NOTE: Also check junction block connectors C-212, C-215 and
intermediate connector C-27 for loose, corroded, or damaged
terminals, or terminals pushed back in the connector. If junction
block connector C-212, C-215 or intermediate connector C-27
is damaged, repair or replace the damaged component(s) as
described in GROUP 00E, Harness Connector Inspection

P.00E-2

.

Q: Is the wiring harness between sunroof motor assembly

connector D-04 (terminal 1) and fusible link (5) 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.
