SUNROOF MOTOR ASSEMBLY
SUNROOF MOTOR ASSEMBLY : Description

INFOID:0000000004205532

• BCM supplies power.

• CPU is integrated in sunroof motor assembly.

• Tilts up/down & slides open/close by sunroof switch operation.

• In order to close sunroof lid certainly with the signal from combination meter at the time of high speed run,

the sunroof motor torque at the time of tilt-down operation is controlled.

1.

 CHECK SUNROOF MOTOR FUNCTION

Do tilt up/down & slide open/close functions operate normally with sunroof switch?
Is the inspection result normal?

YES

>> Sunroof motor assembly is OK.

NO

>> Refer to 

RF-12, "SUNROOF MOTOR ASSEMBLY : Diagnosis Procedure"

.

SUNROOF MOTOR ASSEMBLY : Diagnosis Procedure

INFOID:0000000004205534

SUNROOF MOTOR ASSEMBLY

1.
