SUNROOF SYSTEM

ANTI-PINCH FUNCTION

The CPU of sunroof motor assembly monitors the sunroof motor operation and the sunroof position (fully-
closed or other) by the signals from sunroof motor.
When sunroof motor detects an interruption during the following slide close and tilt down operation, sunroof
switch controls the motor for open and the sunroof will operate until full up position (when tilt down operate) or
150 mm (5.91 in) or more in an open direction (when slide close operate):
• close operation and tilt down when ignition switch is in the “ON” position

SUNROOF MOTOR ASSEMBLY

SUNROOF MOTOR ASSEMBLY : Description

INFOID:0000000000961750

• BCM supplies power.
• It is sunroof motor and CPU integrated type.
• Tilts up/down & slides open/close by sunroof switch operation.
• In order to close sunroof lid certainly with the signal from unified meter and a/c amp. at the time of high

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

SUNROOF MOTOR ASSEMBLY : Component Function Check

INFOID:0000000000961751

1.

CHECK SUNROOF MOTOR FUNCTION

Do tilt up/down & slide open/close operations operate normally with sunroof switch?

Is the inspection result normal?

YES

>> Sunroof motor assembly is OK.

NO

>> Refer to 

RF-9, "SUNROOF MOTOR ASSEMBLY : Diagnosis Procedure"

SUNROOF MOTOR ASSEMBLY : Diagnosis Procedure

INFOID:0000000000961752

SUNROOF MOTOR ASSEMBLY

1.

CHECK POWER SUPPLY CIRCUIT

1.
