GENERAL DESCRIPTION
A motor-driven outer slide-type glass sunroof with a tilt-up mechanism is adopted in GSR as optional equipment. Even when the sunroof is fully closed, a sufficient amount of light and a feeling of openness can still be obtained by opening the sunroof sunshade.
SUNROOF DIAGNOSIS
The sunroof system is controlled by the Simplified Wiring System (SWS). For troubleshooting, refer to SWS DIAGNOSIS .
Scheme 13
WATER TEST
Check if there are any leaks in the sunroof by the following procedure.
- Fully close the roof lid glass.
- 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.
- 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.
- Check if any water leaks can be found in the room while watering. Even though there are any water leaks around the roof lid glass, it can be acceptable as long as water is caught in the drip area.
Scheme 14
SUNROOF TIMER FUNCTION CHECK
Keep the door closed, turn OFF the ignition switch and check to see if the sunroof operates for 30 seconds after that. If operations malfunction then execute troubleshooting remedies (Refer to SWS DIAGNOSIS ).
SUNROOF FIT ADJUSTMENT
- Fully close the roof lid glass.
- Fully open the sunshade.
- Loosen the screws fixing the roof lid glass assembly, move the roof lid glass assembly along the long hole of the drive cable assembly, adjust the height of the roof lid glass, and check that the space between the roof lid glass and body is consistent along the whole circumference.
- After adjusting, check that the sunroof operates smoothly.
Scheme 15
SUNROOF SAFETY FUNCTION CHECK
- Close the roof lid glass by applying an approximately 10mm (0.39 inch) thickness wood chip placed in a right angle with the roof lid glass.
- Check to see if the roof lid glass opens after the motor turns when the roof lid glass catches the wooden chip (Refer to «SWS DIAGNOSIS»(/mitsubishi/lancer-evolution/viii-2003-2005/remont/communication-devices/#simplified-wiring-system-sws-evolution) ).
Scheme 16
SUNROOF CHECK
Check to see that the sunroof operates by pressing the sunroof switch. Troubleshoot if operations malfunction. (Refer to SWS DIAGNOSIS .)
ROOF LID GLASS OPERATION CURRENT CHECK
- Remove the fuse of the sunroof, then connect the circuit tester as shown in the Figure.
- Turn ON the sunroof switch, then measure the operating current of the intermediary segment when operation is starting, the sunroof is fully closed, the sunroof is fully opened and the sunroof is tilted fully up. Standard value: 7 A or less [at 20 °C (68 °F)]
- Check the following areas if the operating current of exceeds the standard value
- Sunroof assembly installation, deformation and trapping of any foreign materials.
- Drive cable fastening
- Tilting of roof lid glass
Scheme 17
SUNROOF INITIALIZED ADJUSTMENT
- Assemble the roof lid glass assembly and sunroof motor assembly on the sunroof assembly.
- Connect the sunroof motor assembly connector and sunroof switch connector to the wire ring harness connector on the vehicle side.
- Fully open the roof lid glass by pressing the sunroof switch then fully close the sunroof by repeatedly pressing the close switch.
- Continuously press the close switch for a minimum of 3 seconds from the fully closed state.
- Press the open switch to fully open the sunroof, then press the close switch to fully close the sunroof.
Note. Do not stop the sunroof before the sunroof is fully opened or fully closed in Step 5 . If the fully open or close operation is interrupted/stopped, then start over from Step 3 .
OPERATION CHECK
Check that the following items. If faulty, replace the sunroof-ECU (sunroof motor assembly).
| CAUTION | Check that the following items are normal before carrying out this operation check. |
- Installation condition of the sunroof assembly.
- Installation condition, deformation, and foreign material on the sunroof drive cable.
- Sunroof lid glass installation condition.
- Sunroof switch and sunroof motor assembly.
BASIC OPERATION
| NO. | SUNROOF FUNCTION | REQUIREMENTS FOR THE SUNROOF TO FUNCTION | NORMAL OPERATION | |
|---|---|---|---|---|
| 01 | OPEN | Ignition switch: ON Sunroof switch: OPEN | The sunroof opens fully and automatically. | |
| 02 | CLOSE | Ignition switch: ON Sunroof switch: CLOSE/TILT-DOWN | The sunroof closes while the sunroof switch is pushed to the CLOSE/TILT-DOWN position. | |
| 03 | TILT-UP | Ignition switch: ON Sunroof switch: TILT-UP | The sunroof tilts up fully and automatically. | |
| 04 | TILT-DOWN | Ignition switch: ON Sunroof switch: CLOSE/TILT-DOWN | The sunroof closes while the sunroof switch is pushed to the CLOSE/TILT-DOWN position. | |
| 05 | AUTOMATIC OPERATION INTERRUPTION | A | Ignition switch: ON Sunroof switch: TILT-UP or CLOSE/TILT DOWN (Push the sunroof switch to the CLOSE/TILT-DOWN position while the sunroof is automatically opening and release the switch within two seconds) | The sunroof stops the automatic opening operation. |
| B | Ignition switch: ON Sunroof switch: CLOSE/TILT DOWN (Push the sunroof switch to the CLOSE/TILT-DOWN position more than two seconds while the sunroof is automatically opening) | The sunroof stops the automatic opening operation, and the sunroof closes while the sunroof switch is pushed to the CLOSE/TILT-DOWN position. | ||
BASIC OPERATION
JAM PREVENTING MECHANISM
| NO. | SUNROOF FUNCTION | REQUIREMENTS FOR THE SUNROOF TO FUNCTION | NORMAL OPERATION |
|---|---|---|---|
| 01 | CLOSE | Ignition switch: ON Sunroof switch: CLOSE/TILE-DOWN Sunroof initial position: being closed or opened Interrupt the sunroof operation before the sunroof is fully closed. | After you interrupt the sunroof operation, it opens to the predetermined distance and then stops automatically. |
| 02 | TILE-DOWN | Ignition switch: ON Sunroof switch: CLOSE/TILT-DOWN Sunroof initial position: being tilting down Interrupt the sunroof operation before the sunroof is fully closed. | The sunroof tilts up automatically after it is interrupted. |
JAM PREVENTING MECHANISM
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.
- If you close the sunroof fully while the timer is working, the sunroof timer function is cancelled after that sunroof operation.
- If you turn the ignition switch to the LOCK (OFF) position while the timer is working, the sunroof will continue moving until it closes fully, regard-less of the time-out period.

<< A>> DRAIN PIPE REMOVAL
Tie a cord to the end of the drain pipe, and wind tape around it so that there is no unevenness. Then pull the drain pipe out to the wheel house side.
Scheme 19
<< B>> SUNROOF ASSEMBLY REMOVAL
Using round nose pliers or a similar tool, turn the caulking the direction shown in the illustration, and then remove the sunroof assembly.
Scheme 20
Scheme 21
- Tie the cord that was used during removal to the end of the drain pipe, and wind tape around it so that there is no unevenness.
- Pull the cord to pass through the drain pipe.
- Install the grommet, and then position the drain pipe so that it protrudes from the grommet as shown in the illustration.
Scheme 22
>>B<< SUNROOF MOTOR ASSEMBLY INSTALLATION
- Install the roof lid glass assembly and the sunroof motor assembly with the sunroof assembly.
- Connect the sunroof motor assembly connector and the sunroof switch connector to the vehicle wiring harness connector.
- Operate the sunroof switch to slide the roof lid glass to the fully-open position, and then tilt it up in steps of 30 mm (1.18inch) to the fully-open position and then keep pressing the switch for 0.5 second or more.
Note. During initialization (learning mode), use only the CLOSE/OPEN switch to move the roof lid glass from the fully-closed position to the fully-open position. During initialization, the TILT UP switch will not work when pressed. Furthermore, the sunroof-ECU will stop running in learning mode as soon as the glass is titled up.
