STEP 4. Check the ignition switch (IG2) 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) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal 2 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 6.
NO :  Go to Step 5.

STEP 5. Check the wiring harness between sunroof motor 
assembly connector D-04 (terminal 2) and ignition switch 
(IG2).

NOTE: Also check junction block connectors C-215 and C-205 
for loose, corroded, or damaged terminals, or terminals pushed 
back in the connector. If junction block connector C-215 or 
C-205 is damaged, repair or replace the damaged compo-
nent(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 2) and the ignition switch (IG2) 
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 6. Check the ground circuit to the sunroof motor 
assembly. Measure the resistance at sunroof motor 
assembly connector D-04.
(1) Disconnect sunroof motor assembly connector D-04 and 

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

(2) Measure the resistance value between terminal 2 and 

ground.

• The resistance should be 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 8.
NO :  Go to Step 7.

STEP 7. Check the wiring harness between sunroof motor 
assembly  connector D-04  (terminal 5) and ground.
Q: Is the wiring harness between sunroof motor assembly 

connector D-04 (terminal 5) and ground 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 8. Check the sunroof switch connector D-03-1 for 
loose, corroded or damaged terminals, or terminals 
pushed back in the connector.
Q: Is sunroof switch connector D-03-1 in good condition?

YES : Go to Step 9.
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 9. Check the sunroof switch.
(1) Remove the sunroof switch. Refer to GROUP 42, Sunroof 

Assembly 

P.42-78

.

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

"OPEN", "TILT UP" or "CLOSE/TILT DOWN" positions.

Q: Does the check meet the specified conditions?

YES : Go to Step 10.
NO :  Replace the sunroof switch. Check that the sunroof 

works normally.

STEP 10. Check the ground circuit to the sunroof switch. 
Measure the resistance at sunroof switch connector 
D-03-1.
(1) Disconnect sunroof switch connector D-03-1 and measure 

the resistance available at the wiring harness side of the 
connector.

(2) Measure the resistance 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 14.
NO :  Go to Step 11.
