GENERAL INFORMATION

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 sunroof 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 transmitted by ETACS-ECU, the sunroof timer function stops at this time.

SUNROOF DIAGNOSIS

TROUBLESHOOTING STRATEGY

Refer to GROUP 00, How to Use Troubleshooting/Inspection Service Points, Troubleshooting Contents.

DIAGNOSTIC TROUBLE CODE CHART

CAUTION On troubleshooting, if the ignition switch is turned ON while disconnecting connector(s), diagnostic trouble code(s) associated with other system may be set. On completion, confirm all systems for diagnostic trouble code(s). If diagnostic trouble code(s) are set, erase them all.

SUNROOF MOTOR ASSEMBLY TERMINAL CHECK

SPECIAL TOOLS

ON-VEHICLE SERVICE

WATER TEST

Check if there are any leaks in the sunroof by the following procedure.

1. Fully close the sunroof lid glass.

2. Adjust the water pressure so that water comes out of the hose to a height of approximately 50 cm (19.7 inches) when the hose is held vertically facing upwards.

3. Hold the end of the hose approximately 30 cm (11.8 inches) above the roof and let the water run onto the weatherstrip for 5 minutes or more.

4. Check if any water leaks can be found in the room while watering. Even though there are any water leaks around the sunroof lid glass, it can be acceptable as long as water is caught in the drip area.

SUNROOF FIT ADJUSTMENT

1. Fully close the sunroof lid glass.

2. Fully open the sunshade.

3. Loosen the sunroof lid glass assembly mounting screws.

Adjust the sunroof lid glass height by moving the sunroof lid glass assembly along the sunroof lid guide oblong hole so that the clearance between the sunroof lid glass and the vehicle body is even throughout the circumference.

4. After adjustment, check that the sunroof operates smoothly.

SUNROOF SAFETY FUNCTION CHECK

1. Close the sunroof lid glass while placing an approximately 10 mm thick piece of wood at right angles with the sunroof lid glass.

2. Check to see if the sunroof motor assembly turns in the opposite direction and the sunroof lid glass opens when the sunroof lid glass touches the wood. If any problem occurs, perform troubleshooting.

SUNROOF CHECK

Check to see that the sunroof operates by pressing the sunroof switch. If it does not operate, perform troubleshooting.

SUNROOF TIMER FUNCTION CHECK

Check the system as described below. If the system does not work, carry out troubleshooting.

• Close the door and turn the ignition switch to the LOCK (OFF) position, and then check that the sunroof operates for 30 seconds.
• Close the door and turn the ignition switch to the LOCK (OFF) position. While the timer is on, open the driver's or front passenger's door, and check that the sunroof stays during the operation. (When the driver's or front passenger's door is opened while the timer is on, the timer will be turned off.)

SUNROOF LID GLASS OPERATION CURRENT CHECK

1. Remove the fuse of the sunroof to check that it is normal, then connect the circuit tester as shown in the Figure.

2. Turn ON the sunroof switch, then measure the operating current when the sunroof lid glass is halfway opened.

Standard value: 7 A or less [at 20 ºC (68 ºF) ]

3. Check the following areas if the operating current exceeds the standard value:

• Sunroof installation, deformation and presence of any foreign substances.
• Drive cable installation.
• Tilting of sunroof lid glass.

LEARNING PROCEDURES OF THE SUNROOF FULLY CLOSED POSITION

SHIFTING CONDITIONS FOR THE FULLY CLOSED POSITION ADJUSTMENT MODE

• When shifting to the forced fully closed position adjustment mode How to shift to the forced fully closed position adjustment mode

1. Turn the ignition switch to the "ON" position.
2. With the sunroof lid glass stopped (the position of the sunroof lid glass can be any position between fully opened and fully closed), press and hold the up switch for 10 seconds.

• When the anti-trap function (safety mechanism) is activated consecutively five times
• When the position information may be incorrect due to abnormal power supply during the sunroof operation

NOTE: When installing the sunroof assembly, or installing/ replacing the sunroof motor assembly, operate the forced fully closed position adjustment mode to adjust the fully closed position.

HOW TO ADJUST THE FULLY CLOSED POSITION FORCED FULLY CLOSED POSITION ADJUSTMENT MODE

1. With the sunroof lid glass stopped (the position of the sunroof lid glass can be any position between fully opened and fully closed), press and hold the up switch.

NOTE: If operating the up switch moves the sunroof normally, use the open switch to fully open the sunroof lid glass.

After the sunroof lid glass stops, press and hold the up switch.

2. Use the up switch to set the sunroof lid glass to the tilt-up position. The sunroof lid glass activates for approximately 30 mm and stops automatically when the switch is pressed once. Repeat this operation until the tilt-up position is reached and hold there for 3 seconds so that the fully closed position learning is completed.

HOW TO ADJUST THE FULLY CLOSED POSITION SUCH AS WHEN THE SAFETY FUNCTION IS ACTIVATED CONSECUTIVELY FIVE TIMES

Use the up switch to set the sunroof lid glass to the tilt-up position.

The sunroof lid glass activates for approximately 30 mm and stops automatically when the switch is pressed once.

Repeat this operation until the tilt-up position is reached and hold there for 3 seconds so that the fully closed position learning is completed.

SUNROOF OPERATION CHECK

CAUTION Check that the following items are normal before carrying out this operation check:

• Installation condition of the sunroof assembly
• Installation condition, deformation and contamination of the sunroof drive cable
• Installation condition of sunroof lid glass
• Sunroof switch and sunroof motor assembly

Check that the following items. If faulty, replace the sunroof motor assembly.

BASIC OPERATION

SUNROOF TIMER MECHANISM

In cases except the following, the basic operation and jam preventing mechanism will be maintained for thirty seconds after the ignition switch is turned to the "LOCK" (OFF) position (Sunroof timer function).

• If you open a door within that period (i.e. a door switch is on), the sunroof timer function will be cancelled immediately.

SAFETY MECHANISM

• If any obstacle such as a hand or a head is detected to be pinched during a sunroof lid glass closing operation, the sunroof lid glass is opened by approximately 200 mm (7.9 inches) or more.

  (Safety mechanism)

• During the sunroof lid glass closing operation, by continuing the sunroof close switch operation, the sunroof can be forcibly closed without activating the safety mechanism even when an obstacle is detected to be pinched.
• During the safety mechanism activation, when the sunroof close switch is operated, the sunroof lid glass stops. By continuing the close switch operation, the sunroof lid glass can be forcibly closed without activating the safety mechanism even when an obstacle is detected to be pinched.
