SUNROOF SYSTEM

INPUT/OUTPUT SIGNAL CHART

SUNROOF OPERATION

• Sunroof motor assembly operates with the power supply that is output from BCM while ignition switch is ON

or retained power is operating.

• Tilt up/down & slide open/close signals from sunroof switch enables operate sunroof motor to move arbi-

trarily.

• Sunroof motor assembly receives a vehicle speed signal from unified meter and A/C amp. and controls the

sunroof motor torque of tilt-down at the time of high speed operation.

AUTO OPERATION

Sunroof AUTO feature makes it possible to slide open and slide close or tilt up and tilt down the sunroof with-
out holding the sunroof switch in the slide open/tilt down or slide close/tilt up position.

RETAINED POWER OPERATION 

• Retained power operation is an additional power supply function that enables sunroof system to operate dur-

ing 45 seconds even when ignition switch is turned OFF.

RETAINED POWER FUNCTION CANCEL CONDITIONS

• Front door CLOSE (door switch OFF)

→

OPEN (door switch ON).

• When ignition switch is ON again.

SUNROOF SYSTEM

• When timer time passes. (45 seconds)

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

DIAGNOSIS SYSTEM (BCM)

The BCM records the following condition at the moment a particular DTC is detected.
• Vehicle Speed
• Odd Trip Meter
• Vehicle Condition (BCM detected condition)

IGN Counter

IGN counter indicates the number of times that ignition switch is turned ON after DTC is detected.
• The number is 0 when a malfunction is detected now.
• The number increases like 1 

→

 2 

→

 3...38 

→

 39 after returning to the normal condition whenever ignition

switch OFF 

→

 ON.

• The number is fixed to 39 until the self-diagnosis results are erased if it is over 39.
