Check voltage between sunroof motor assembly connector R4
terminals 7 and 9 and ground.

Is the voltage as specified?

YES

>> GO TO 4

NO, TERMINAL 7>>Check sunroof motor circuit breaker, connector and harness. Refer to PG section, main

wire harness layout.

NO, TERMINAL 9>>GO TO 2

2.

 CHECK SUNROOF MOTOR RETAINED POWER SUPPLY CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect BCM connector M20.

3.

Check continuity between BCM connector M20 (A) and sunroof
motor assembly connector R4 (B).

4.

Check continuity between BCM connector M20 (A) and ground.

SUNROOF SWITCH CIRCUIT

Description

INFOID:0000000001724566

A circuit breaker supplies constant battery power to the sunroof motor assembly. The BCM supplies retained
power to the sunroof motor assembly when the key is ON or during retained power operation. The open and
close functions of the sunroof motor assembly are controlled by the sunroof switch. 

Component Function Check

INFOID:0000000001724567

1.

 CHECK SUNROOF MOTOR FUNCTION

Do open and close functions operate normally with the sunroof switch?

Is the inspection result normal?

YES

>> Sunroof motor assembly is OK.

NO

>> Refer to 

RF-11, "SUNROOF MOTOR ASSEMBLY : Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000001724568

1.

 CHECK SUNROOF SWITCH INPUT SIGNAL 

1.

Turn ignition switch ON.

2.

Check voltage between sunroof switch connector and ground.

Are the voltage measurements as specified?

YES

>> Sunroof switch is operating normally. 

NO

>> GO TO 2

2.

 CHECK SUNROOF SWITCH CIRCUITS

1.

Turn ignition switch OFF.

2.

Disconnect sunroof motor assembly connector R4 and sunroof
switch connector R6.

3.

Check continuity between sunroof motor assembly connector
R4 (A) and sunroof switch connector R6 (B) and.

4.

Check continuity between sunroof motor assembly connector R4 (A) and ground. 

Are the continuity test results as specified?

YES

>> GO TO 3
