Fuel Filler Cover lock

Fuel Fill Door Description and Operation
The fuel door latch actuator shares the circuit with the driver door latch assembly. The body control module (BCM), upon receipt of a lock switch lock or unlock signal, will switch the appropriate door lock actuator, as well as a fuel filler door release actuator control circuits to battery positive voltage. The opposing side of the door lock and fuel filler door release actuators is connected to ground by the I/P fuse block through the other door lock actuator control circuit and the doors, along with the fuel filler door release, will lock or unlock as commanded.
Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the fuel door release actuator.
2. Test for less than 1 ohm between the control circuit terminal 1 and ground.
?‡'
If greater than the specified range, test the control circuit for a short to voltage or an open/high resistance.

3. Test for less than 1 ohm between the control circuit terminal 2 and ground.
?‡'
If greater than the specified range, test the control circuit for a short to voltage or an open/high resistance.

4. Connect a test lamp between the control circuit terminal 1 and control circuit terminal 2.
5. Ignition ON, command the doors to LOCK and UNLOCK by using the door lock switch. The test lamp should illuminate while commanding the LOCK and UNLOCK states.
?‡'
If the test lamp remains OFF during either command, test either control circuit for a short to ground.

6. If all circuits test normal, test or replace the fuel door release actuator.

Component Testing

1. Ignition OFF, disconnect the harness connector at the fuel door release actuator
2. Install a 15A fused jumper wire between the control terminal 1 and 12V. Momentarily install a jumper wire between the control terminal 2 and ground. The fuel door release actuator should perform the LOCK/UNLOCK function.
?‡'
If the function does not perform as specified, replace the fuel door release actuator.

3. Reverse the jumper wires. The fuel door release actuator should perform the UNLOCK/LOCK function.

?‡'
If the function does not perform as specified, replace the fuel door release actuator.

I am not fameliar with your car type but in general:
1- try to remove door cover gently after unscrew the handles
2- if you get orginal motor then just disconnect wires (keep track of colors)
3- install new one

if you bought comercial motor for al types of car do as below:
- All material you need will be included with the motor
- choose the motor location carefuly Notes 2 things
A- your door cover can positioned in it s location
B- motor will not block your window glass from get down
- drill holls to install your new motor
- choose location of motor bar carfuly

- try to lock / unlock it many times before installing the door cover

Do you know anything about automotive electronic's ? computer controlled systems ? There is electronic control modules in side the doors of your vehicle that control the operation of the windows an lock's , plus the instrument cluster is a module too . Your vehicle has about 10 different control modules and thet are all hooked on a serial data communication network ,to share info. The fuel tank sending unit in the gas tank is wired to the PCM - engine computer , The PCM sends fuel level info to the gauge in the instrument cluster on this serial data network . Your best bet ,take an have the vehicle checked out by a qualified repair shop .
The power door lock system consists of the following components:
• Driver Door Module (DDM)
• Passenger Door Module (PDM)
• Liftgate Module (LGM)
• Door lock relay
• Door unlock relay
• Body Control Module (BCM)
• Reversible door lock actuators in each of the doors
• LR/RR LOCKS 10A fuse (relay supply voltage)
• Door lock switches in driver and passenger doors (switches are integral components to the DDM and PDM)

Power Door Lock Operation
The power door lock switches are integral components of the DDM and PDM. The switches are two position normally open rocker switches. When placed in either the lock or unlock positions, the switches provide a direct input to the DDM or PDM. The DDM or PDM monitors these inputs and sends a Class 2 message indicating a change in the switch's respective position. Modules which activate the power door lock motors receive the Class 2 message and activate the motor in the appropriate direction to lock or unlock the vehicle's doors and liftgate. The modules which activate the power lock motors are:
• DDM (driver door lock actuator).
• PDM (passenger front door lock actuator).
• BCM (both rear door lock actuators).
• LGM (liftgate door lock actuator).
The DDM, PDM and LGM are directly connected to the respective door lock actuator through the door lock motor lock and unlock circuits. Once a door lock or unlock request has been received, the module will supply battery voltage to one side of the actuator and ground the other causing the doors to lock or unlock.

The modules probably have DTC'S - diagnostic trouble codes stored , these would point a auto tech in a positive diagnostic direction .

You have listed the vehicle is a 1987 Jaguar XJ6. The trunk is not electronic and only unlocks with the key as well as both the gas doors. Any issues here then it is your key or the actual trunk latch. If you do have a 1988 model year then the trunk lock has 3 positions. locked all the time, unlocked all the time or the vertical position locks and unlocks with the vehicles drivers door lock. If the trunk button (paddle) is loose and moves but nothing happens then the inside rod has come loose and you will have to manually operate the latch by removing the license plate and taking a long screw driver through the lower plastic bungs. The fuel flap is a separate unite and does have a manual release but you need to open the trunk to get to it. If the fuel flap stays locked all the time then the actually filler neck module will need replacing.If you have a 1997 which has the electronic release button to open the trunk (95-2003) Then you will need to firstly lock all door and unlock the drivers door 2 times. Check the fuel flap is now released, if not then the fuel flap actuator located on the filler neck inside the trunk is bad. If the trunk does not open with the remote, inside car switch and trunk mounted switch then the passenger side trunk harness is broken. Open the trunk with the key and on the right(passenger) hinge there is a grey plastic cover, remove that cover and carefully peel back the wiring harness cover and you will find 1 or more broken wires. Once the wires are repaired then I recommend you zip tie them in place and retest the trunk release button.If this does not answer any of your questions please feel free to email [email protected]

For 2005 Toyota Corolla (and Matrix), the location of the cabin air filter is inside of the drawer (passenger side). Open the drawer, you will see a screw on the RIGHT hand side. Unscrew it with a cross shape screw driver. Unlock the drawer from the screw holder. And take the drawer out of the cabin. After the removal, you will be able to see the location of the cabin air filter. There is a lock at each side of the filter cover. For each side, use two fingers to pinch the lock and pull out the cover. You will see the old filter after removing the cover. Pull it out, and insert your new filter.
Put the cover back. Make sure the two locks are firmly locked. Put the drawer back. To make this work easier, you may lock the bottom of the drawer first, as there are TWO locks on each side of the bottom drawer. Close the drawer to see if the position is right. Place the screw back, that's all

Hello,

I think, I don´t understand your question ;)

The fuel tank is locked automatically when you lock the car. The cover has it´s own locking module conneced to the central locking. If it does not lock, the module should be checked for damage.

There are Valet keys (often with a green knob) that will
only unlock the front doors and the ignition but not the
glove box nor boot/trunk.

When either the front door locks or the console button is
pressed, all the doors should lock. Likewise, when either
front door is unlocked, all the doors fuel filler lid and if
selected, the boot will also unlock.

Boot lock has three positions. Unlocked to the left,
automatic with the doors in the center, always locked to the
right. Simply remove the key in what ever position you desire.

The locks can get confused and not work correctly. Simply
sit in the car and manually lock all the doors. That will
usually get the locking module sane again.

IT SOUNDS LIKE IT IS TIME TO REPLACE HOLDER BEHIND FUEL DOOR EVEN IF YOU BREAK IT OFF TO OPEN ITS ONLY A FEW BUCKS TO REPLACE
