Pinpoint Test G: The One-Touch Open/Close Is Inoperative
- Normal Operation and Fault Conditions
All of the roof opening panel switches are single position switches that can achieve one touch operation in either direction by pressing the switch for less than 1 second. For manual operation, simply press and hold the switch until the roof opening panel or shield is in the desired position and release the switch. When the front roof opening panel is in the fully closed or between fully closed and full vent position the vent switch operates in either manual or one touch operation similar to the roof opening panel and shield switches. If the shield is not open at lease to the front of the rear fixed glass (comfort stop) when the vent or roof opening panel glass open switch is pressed then the shield will first open to the comfort stop position before the roof opening panel glass will move. The roof opening panel glass and the shield will not move at the same time. One touch operation of either the roof opening panel or the shield can be cancelled anytime by pressing any roof opening panel switches during operation. When the sunroof is open and the sunroof close switch is pressed to for one touch operation, a signal is sent to the sunroof motor through on the sunroof close circuit causing the sunroof to perform a one-touch close operation. The sunroof open one touch operation is the same as sunroof close, except if the shield (sunshade) is closed when the sunroof motor is commanded to perform a one-touch open operation the motors will communicate and the shield (sunshade) motor will perform a one-touch open operation, then the sunroof motor will perform the one-touch open operation requested. The shield one touch operation is the same as the sunroof except if the sunroof is open, the shield will only move to the comfort stop position. The sunroof will not open as a result of a shield one touch close operation. For more information on the operation. REFER to: Roof Opening Panel - System Operation and Component Description .
Possible Sources
- Roof opening panel initialization (sunroof motor or shield (sunshade) motor)
- Roof opening panel motor/module assembly
- Shield (sunshade) motor
- Roof opening panel control switch
- G1 CHECK THE ROOF OPENING PANEL MOTORS FOR INITIALIZATION
- Carry out the roof opening panel motor initialization procedure for the sunroof and shield (sunshade). REFER to: Power Roof Opening Panel Initialization .
- Operate the system using one-touch.
Is the concern still present?
Yes GO to G2 No The system is operating normally at this time. The roof opening panel motor was not initialized. - G2 CHECK THE ROOF OPENING PANEL MOTOR/MODULES AND SWITCH FOR CORRECT OPERATION
- Ignition OFF.
- Disconnect All sunroof system and related in-line connectors.
- Check for:
- corrosion - install new connector or terminals and clean module pins
- damaged or bent pins - install new terminals or pins
- pushed-out pins - install new pins as necessary
- Connect all sunroof system and related in-line connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
Is the concern still present?
Yes CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new roof opening panel motor and shield motor. REFER to: Roof Opening Panel Motor . TEST the system for normal operation. If the concern still exists, INSTALL a new roof opening panel control switch. REFER to: Roof Opening Panel Control Switch . No The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
