.

CIRCUIT OPERATION

• The sunroof motor assembly is energized 

through fusible link (1) and (4).

• 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 

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

DIAGNOSIS

Required Special Tool:

• MB991223: Harness Set

STEP 1. Check the sunroof motor assembly connector 
F-02 for loose, corroded or damaged terminals, or 
terminals pushed back in the connector.
Q: Is sunroof motor assembly connector F-02 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

The sunroof should now work normally.

STEP 2. Check the fusible link (4) line of power supply 
circuit to the sunroof motor assembly. Test at sunroof 
motor assembly connector F-02.
(1) Disconnect sunroof motor assembly connector F-02 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 be 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.

STEP 3. Check the harness wires between sunroof motor 
assembly connector F-02 (terminal 1) and fusible link (4).

NOTE: Also check intermediate connectors F-24, D-26 and 
D-28 for loose, corroded or damaged terminals, or terminals 
pushed back in the connectors. If intermediate connector F-24, 
D-26 or D-28 is damaged, repair or replace the damaged com-
ponent(s) as described in GROUP 00E, Harness Connector 
Inspection 

P.00E-2

.

Q: Is the wiring harness between sunroof motor assembly 

connector F-02 (terminal 1) and fusible link (4) 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. The sunroof 
function should now work normally.

STEP 4. Check the ignition switch (IG2) circuit to the 
sunroof motor assembly. Test at sunroof motor assembly 
connector F-02.
(1) Disconnect sunroof motor assembly connector F-02 and 

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

(2) Turn the ignition switch to “ON” position.

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

• The voltage should be approximately 12 volts (battery 

positive voltage).

Q: Is the measured voltage approximately 12 volts (battery 

positive voltage)?
YES : 
Go to Step 6.
NO :  Go to Step 5.
