SUNROOF FUNCTION

A motor-driven inner slide-type glass sunroof with a 
tilt-up mechanism is available in some models as 
optional equipment. Even when the sunroof is fully 
closed, a sufficient amount of lighting and a feeling of 
openness can still be obtained by opening the sun-
roof sunshade.

.

SUNROOF TIMER FUNCTION

The sunroof ECU (integrated into the sunroof motor 
assembly) receives the ignition switch (IG1) signal 
transmitted by ETACS-ECU. If the ignition switch 
(IG1) signal turns OFF, the sunroof ECU allows the 
sunroof switch to open/close (timer activation) the 
sunroof for approximately 30 seconds. During the 
timer operation, if the driver’s or passenger’s door 
open is detected from the door switch signal trans-
mitted by ETACS-ECU, the sunroof timer function 
stops at this time.

COMMENTS ON TROUBLE SYMPTOM

When the terminal voltage of the sunroof motor 
assembly is 8 V or less, or 18 V or more, and if it con-
tinues for 60 seconds, the sunroof motor assembly 
will set the diagnostic trouble code No. L0630. 

.

PROBABLE CAUSES

• Malfunction of the sunroof motor assembly

• Damaged wiring harness and connectors

DIAGNOSTIC PROCEDURE

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 switch 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 wiring harness between sunroof motor 
assembly connector D-04 (terminal 6) and fusible link (34).

• Check the power supply line for open circuit and short cir-

cuit.

NOTE: Also check ETACS-ECU connectors C-309 and C-316 
for loose, corroded, or damaged terminals, or terminals pushed 
back in the connector. If ETACS-ECU connectors C-309 and 
C-316 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 6) and fusible link (34) in good 
condition?
YES : Go to Step 3.
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.
