Question about Hyundai Tiburon

1 Answer

03 Tiburon sunroof

I have gone thru the diagnostics to verify both switches (tilt, open) are good. The proper continuity and voltages present at wire plug going into control module. The reset procedure only makes the motor buzz, or rapid clicking longer than 20 second. (10 sec advised by dealer)

When the open/close button is pressed, it sounds like the motor wants to work. The tilt/close button has no response.
Unable to take car 350 miles to dealer, as body kit too low! Thus i must make it work. :(
Can anyone tell me if I'm looking at the Sunroof Motor OR Control module as the culprit!
I'm leaning toward the drive in the motor not engaging?

Power Sunroof System Components
The power sunroof system consists of the following components:
• One tilting glass sunroof panel--For sunroof vent functions
• Three sliding glass sunroof panels, which allow the sunroof to open in sections
• Power sunshade panel--An adaptable panel which is rolled out or rolled in and stored by the sunshade motor/actuator in order to cover or uncover the sunroof glass panels
• Power sunroof switch--A rotary style switch controlling sunroof switch signal inputs to the sunroof motor/actuator
• Power sunshade switch--A momentary press style switch controlling sunshade switch signal inputs to the sunshade motor/actuator
• Power sunroof motor/actuator--Comprised of both the sunroof motor/actuator and the sunroof electronic control module, it is sometimes referred to as the sunroof control module/motor assembly.
• Power sunshade motor/actuator--Comprised of both the sunshade motor/actuator and the sunshade electronic control module, it is sometimes referred to as the sunroof slave module.
Sunroof Motor/Actuator and Sunroof Switch
The sunroof motor/actuator assembly is located at the rear of the passenger compartment, above the rear view window, between the headliner and the roof structure. The sunroof motor/actuator assembly also contains the sunroof electronic control module and the two components are serviced together as a unit.
Battery positive voltage is supplied to the motor/actuator at all times through the 25-amp LAMELLA ROOF fuse located in the rear fuse block. Whenever the ignition is turned to RUN or ACCESSORY, or when the retained accessory power (RAP) system is active, the motor/actuator is also supplied battery positive voltage through the accessory voltage circuit and the 10-amp ROOF/HEAT SEAT fuse which is located in the body control module (BCM). The sunroof motor/actuator is grounded through splice S403 to body ground G302.
The sunroof motor/actuator supplies voltage to the sunroof switch through three internal resistors and three hard wire circuits. The 3 hard wire circuits are:
• Sunroof switch data 1 signal circuit
• Sunroof switch data 2 signal circuit
• Sunroof switch data 3 signal circuit
The sunroof switch, which is also grounded to G302, is a rotary style switch. When the switch control lever is turned in a rotational direction, the appropriate switch contacts and signal circuits for the selected mode are simultaneously opened and/or closed to ground in order to provide the appropriate combination of voltage signals to the sunroof motor/actuator. The sunroof motor/actuator interprets the signals, and then applies battery positive voltage and ground to the appropriate circuits of the integral power sunroof motor in order to move the sunroof glass panels. At the same time, the sunroof motor/actuator sends a serial data message, via the keyword 2000 serial data circuit, to the sunshade motor/actuator to open the sunshade panel in conjunction with the sunroof glass. As the sunroof glass panels slide rearward to the open position, the sunshade motor/actuator simultaneously rolls in the adaptable sunshade panel.
The sunroof switch is mounted in a bezel which is located above the rearview mirror.


Circuit/System Description
The sunroof system is controlled by the sunroof switch and the sunroof control module/motor assembly, which is also known as the motor/actuator assembly.
The sunroof control module is supplied battery positive voltage at all times through the 15A SUNROOF fuse located in the rear fuse block. Whenever the ignition is turned to RUN or ACCESSORY, or when the retained accessory power (RAP) system is active, the module is also supplied voltage through the accessory voltage circuit and the 10-amp ROOF/HEAT SEAT fuse located in the body control module (BCM). The sunroof control module is grounded through the ground circuit at G302.
The sunroof control module supplies voltage to the contacts of the sunroof switch through the sunroof switch close signal circuit and the sunroof switch open signal circuit. The sunroof control module also supplies ground to the switch contacts through the sunroof switch low reference circuit. When the switch is operated, the contacts and signal circuit for the selected mode are closed to ground, the voltage is pulled low in the module, and the appropriate signal is recognized by the control module. The control module then internally applies battery positive voltage and ground to the appropriate circuits of the reversible power sunroof motor in order to move the sunroof glass panel to the open, close, or vent

Sunroof is stuck open and tried to reset it by holding button down for ten seconds and then it moves about half an inch and stays fully open. What do I need to do to get it to close?


Hi Thomas , First you should have it diagnosed by someone who has the tool to do so ! upscale scan tool , factory scan tool !
Diagnostic Starting Point - Roof
Begin the diagnosis with the Diagnostic System Check - Power Sunroof . The Diagnostic System Check will provide the following information:
?€¢
The identification of the control modules which command the system


?€¢
The ability of the control modules to communicate through the serial data circuit


?€¢
The identification of any stored DTCs and their status

The use of the Diagnostic System Check will identify the correct procedure for diagnosing the system and where the procedure is located.
Symptoms
When no DTCs ( diagnostic trouble codes ) are present, begin symptom diagnosis by reviewing the
Sunroof Description and Operation . Reviewing the Description and Operation information will help you determine the correct symptom diagnostic procedure when a malfunction exists. Reviewing the Description and Operation information will also help you determine if the condition described by the customer is normal operation. Refer to Symptoms - Roof in order to identify the correct procedure for diagnosing the system and where the procedure is located.
Important: If the suspected cause of an inoperative sunroof is a power interruption to the sunroof module, the sunroof must be re-initialized. Refer to Sunroof Motor/Actuator Synchronization .
Important: The following must be completed before using the symptom tables.

  1. Perform Diagnostic Starting Point - Roof in order to verify that all of the following are true:
  2. ?€¢
    There are no DTCs set.


    ?€¢
    The control module(s) can communicate via the serial data link.

  3. Review the system operation in order to familiarize yourself with the system functions. Refer to Sunroof Description and Operation .
Visual/Physical Inspection
?€¢
Inspect for aftermarket devices which could affect the operation of the Power Sunroof system. Refer to
Checking Aftermarket Accessories in Wiring Systems.


?€¢
Inspect the easily accessible or visible system components for obvious damage or conditions which could cause the symptom.

Intermittent
Faulty electrical connections or wiring may be the cause of intermittent conditions. Refer to
Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
Symptom List
Refer to a symptom diagnostic procedure from the following list in order to diagnose the symptom:
?€¢
Power Sunroof Inoperative


?€¢
Power Sunroof Does Not Open to Express Position


?€¢
Retained Accessory Power (RAP) On After Timeout in Retained Accessory Power, if the power sunroof should operate longer than 20 minutes after the ignition has been turned OFF


This information is right out of GMC service repair manual !
Sunroof Motor/Actuator Synchronization
Synchronization will be necessary anytime the sunroof module battery positive voltage circuit is interrupted. The sunroof module will be synchronized when the controller learns the full vent position. The sunroof system will ignore any open request until the system has been synchronized.
To synchronize the sunroof:

  1. Turn ON the ignition, with the engine OFF.
  2. Using the close/tilt up portion of the sunroof switch, operate the sunroof glass until it reaches the full vent position.
  3. Verify that the system operates normally.
Once the sunroof glass reaches the full vent position, the actual position is stored in the memory of the sunroof module. The sunroof module will stop the motor one motor revolution before the defined actual positions.

In my 03 mercedes e320 wagon the sunroof opens only half way when auto open is used. Is this normal?


No. Push the open switch until glass is fully open....continue to hold switch for 5 seconds to allow motor to memorize open position...ditto closing.

This also applies to your side windows. Any time battery disconnected or voltage drops below 10.5 volts all convenience memories need resetting like this.

Hold window switch down fully for 5 seconds after glass has gone fully down. .....release switch

Repeat for other windows. Switch must be in second detent position when doing this.

NEVER boost charge this vehicles battery in the car unless GROUND connector disconnected from battery...serious electrical damage can occur if this is not done.

Sunroof on 2003 dodge neon not operating - how do you test the switch? Shouldn't I be able to test the switch itself by use of ohm meter for open/close between pins? I receive no tone between any combo of...


We would suggest isolating the wires that go to the sunroof motor and applying 12 volts and ground to verify that the motor is working properly. If it works in one direction, switch the wires to verify that it works in the other direction, fully closing and opening the sunroof. If the motor checks out okay, then the relay is your problem.

What can I check, besides the fuse, to determine why my 1999 New Jetta power sunroof won't open (there's no indication that it's even getting any power - no sounds or anything)


Did you check fuse #16? It is 15A
If you know how to use a VOM (volts ohm meter) I write down the procedure for testing your sunroofs circuitry.

  1. Check fuse 16 in fuse box
  2. With a test light or with a VOM you will check if you have continuity from the fuse that powers your sunroof switch.
  3. Check the black/white wire connected to the switch if you're receiving 11.5V min. If you do then you have power from fuse to switch.
  4. Check if you have continuity for ground (-) from the interior light switch wire harness by probing the brown wire. If you do then you have a good ground connection for your sunroof motor.
  5. From the fuse (16) and the yellow wire on the switch you should have 11.5V min when you actuate the switch.
  6. From the fuse (16) and the blue wire on the switch you should have 11.5V min when you actuate the switch.
  7. If no voltage in either #4 or #5 above when you actuate the switch then you have a bad switch.
  8. From the switch to the sunroof motor you should have 11.5V min using the yellow and blue wire to the motor. If voltage is not present you have a bad connection from switch to motor.
  9. If you have power to the motor and it doesn't do anything then you have a bad motor and needs replacing.

Motor turns over but no spark changed coil and crank shaft sensor


well replace lots of coils but same with crank sensor on these trucks
  • For this test, an analog (non-digital) voltmeter is needed. Do not remove the distributor connector from the distributor. To perform a complete test of the Camshaft Position Sensor and its circuitry, refer to the DRB II diagnostic tester. Also see the appropriate Diagnostic Charts. To test the sensor only, refer to the following: See: Testing and Inspection
  • Using small paper clips, insert them into the backside of the distributor wire harness connector to make contact with the terminals. Be sure that the connector is not damaged when inserting the paper clips. Attach voltmeter leads to these paper clips.
PROCEDURE
  1. Connect the positive (+) voltmeter lead into the sensor output wire. This is done at the distributor wire harness connector.
  2. Connect the negative (-) voltmeter lead into the ground wire.
  3. Set the voltmeter to the 15 Volt DC scale.
  4. Remove distributor cap from distributor (two screws). Rotate (crank) the engine until the distributor rotor is pointed towards the rear of vehicle. The movable pulse ring should now be within the sensor pickup.
  5. Turn ignition key to ON position. Voltmeter should read approximately 5.0 volts .
  6. If voltage is not present, check the voltmeter leads for a good connection.
  7. If voltage is still not present, check for voltage at the supply wire.
  8. If voltage is not present at supply wire, check for voltage at pin-7 of Powertrain Control Module (PCM) 60-way connector. Leave the PCM connector connected for this test.
  9. If voltage is still not present, perform vehicle test using the DRB II diagnostic scan tool.
  10. If voltage is present at pin-7, but not at the supply wire:
    1. Check continuity between the supply wire. This is checked between the distributor connector and pin-7 at the PCM. If continuity is not present, repair the harness as necessary.
    2. Check for continuity between the Camshaft Position Sensor output wire and pin-44 at the PCM. If continuity is not present, repair the harness as necessary.
    3. Check for continuity between the ground circuit wire at the distributor connector and ground. If continuity is not present, repair the harness as necessary.
  1. While observing the voltmeter, crank the engine with ignition switch. The voltmeter needle should fluctuate between 0 and 5 volts while the engine is cranking. This verifies that the camshaft position sensor in the distributor is operating properly and a sync pulse signal is being generated. NOTE: If sync pulse signal is not present, replacement of the Camshaft Position Sensor is necessary.

MY SUNROOF WONT CLOSE


Check the owner's manual. There should be a section showing how to manually close the sunroof. You will use an allen wrench to turn the gears manually, I just don't know exactly what size or where the hole is located. It is typically located right behind the sunroof with a plug covering the hole in the headliner.
