Central door locking installation

The alarm default setting is type B negative (-) for locking and unlocking, if your car is with type B negative central door locking, you can connect the white locking wire and white-black unlocking wire from EC003N with your car locking and unlocking wire directly, or follow with the Type B negative trigger as below diagram shows to connect with the car central door locking system.
There are 8 different types of door lock systems (Type AH). Please search the vehicle-specific wiring instructions online and the chart below to help determine which door lock system your vehicle uses. Most vehicle factory door lock wires are smaller gauge and located in the driver’s kick panel or under the driver’s dash.
Note: The most common type of door lock systems are Type A positive trigger, Type B negative trigger, and Type C reverse Polarity.
Type A: Positive trigger with three-wire (+) pulse controlling factory lock relays.
Type B: Negative trigger with three-wire (-) pulse controlling factory lock relays.
Type C: Reverse polarity, positive triggered
Type D: Adding one or more aftermarket actuators. These include central locking systems without an actuator in the driver’s door, but with factory actuators in all the other doors. Type D also includes vehicles without power locks, which will have actuators added.
Type E: Electrically-activated vacuum systems. The vehicle must have a vacuum actuator in each door. Make sure that locking the doors from the driver’s or passenger’s side using the key activates all the actuators in the vehicle. This requires a slight modification to the door lock wire harness.
Type F: One-wire system: cut to lock, ground to unlock.
Type G: Positive (+) multiplex. One wire control lock and unlock using a resistor(s).
Type H. Negative (-) multiplex. Same as Type G system, but uses (-) pulse instead.

TYPE A POSITIVE TRIGGER

Type A: positive trigger with three-wire (+) pulse controlling factory lock relays.
There are 3 wires (+) pulse controlling factory locking relays, one pulses 12v for lock, one pulse 12V for unlock, and the last one is for constant 12V. Extra 2 SPDT relays are required.

TYPE B NEGATIVE TRIGGER

Type B: Negative trigger with three-wire (-) pulse controlling factory lock relays.
Two wires resting open circuit, one pulses ground for lock and the other pulse for unlocking.
For this kind of trigger, the vehicle switch will have three wires on it, one wire will test ground all the time. One wire will pulse (-) when the switch locks the doors, and the other wire will pulse (-) when the switch unlocks the doors. This type of system is difficult to mistake for any other type.

Type C Reverse polarity, positive triggered

Motor interrupt central locking:
Two wires resting at the ground, one pulse 12V for lock, the other pluses 12V for unlocking Direct-wired reversing-polarity switches. The switches are wired directly to the motors. This type of system has no factory relays. Extra 2 SPDT relays are required. ****

Type D: Adding one or more aftermarket actuators
For this type of vehicle, there isn’t a motor in the driver’s door (central locking only operates from the driver’s door). An extra door actuator is required.
These include central locking systems without an actuator in the driver’s door, but with factory actuators in all the other doors. Type D also includes vehicles without power locks, which will have actuators added. Vehicles without factory power door locks require the installation of one actuator on each door. This requires mounting the door lock actuator inside the door. Other vehicles may only require one actuator installed in the driver’s door if all door locks are operated when the driver’s lock is used.

Type E: Electrically-activated vacuum systems.
Polarity reverses on a single wire to lock and unlock. Please set the door lock time to 3.5 seconds by a timer delay switch (not included).
The vehicle must have a vacuum actuator in each door. Make sure that locking the doors from the driver’s or passenger’s side using the key activates all the actuators in the vehicle. This requires a slight modification to the door lock wire harness.
The door locks are controlled by an electrically activated vacuum pump. The control wire will show +12v when doors are unlocked and (-) ground when locked.
NOTE: For this kind of central door locking, must program the clock pulse time to be 3.5 seconds.

Type F: One-wire system: cut to lock, ground to unlock.
This type of central door locking system is mainly for Japanese-driven
Single wire in the series negative trigger.
The single wire pulses negative to unlock, and open the circuit to lock. This type of door lock system usually requires a negative pulse to unlock and cutting the wires to lock the door. (for some vehicles, these are reversed). 2 extra SPDT relays are used to interface to this type of system.

Type G: Positive (+) multiplex. One wire control lock and unlock using a resistor(s).
Single wire positive central locking
Single-wire, positive lock, positive unlock.
Two potential (resistor may require) positive riggers.
Single-resistor style: if one resistor is used in the door lock switch/key cylinder, the wire will pulse (+) 12V in one direction and less than + 12V when operated in the opposite direction.
Two resistor types: if two resistors are used in the factory door lock switch/key cylinder, the switch/key cylinder will read less than + 12V in both directions.
Determining the proper resistor values: to determine the resistor values, the door lock switch/key cylinder must be isolated from the factory door lock system. For testing. use a calibrated digital multimeter that is set to ohms,
IMPORTANT: to ensure an accurate resistance reading, do not touch the resistor or leads during testing.

  1. Cut the output ire from the door lock switch/key cylinder in half;
  2. Test with the meter from the switch side of the cut door lock switch/key cylinder wire to a reliable constant +12V source. Some good constant + 12V references are the power input source to the door lock switch/key cylinder, the ignition switch power wire, or the (+) terminal of the battery.
  3. Operate the door lock switch/key cylinder in both directions to determine the resistor values. If the multimeter displays zero resistance in one direction, no resistor is needed for that direction.
  4.  Once the resistor value(s) is determined, refer to the wiring diagram for proper wiring.

Type H: Negative (-) multiplex. Same as Type G system, but uses (-) pulse instead.
Single wire negative central locking
Single-wire, negative lock, negative unlock.
Two potential (resistor may require) negative triggers.
Single-resistor style: if one resistor is used in the door lock switch/key cylinder the wire will pulse ground in one direction and resistance to ground when operated in the opposite direction.
Two resistor types: if two resistors are used in the factory door lock switch/key cylinder, the switch/key cylinder will read resistance to the ground in both directions. Determining the proper resistor values: to determine the resistor values, the door lock switch/key cylinder must be isolated from the factory door lock system. For testing. use a calibrated digital multimeter that is set to ohms.
IMPORTANT: To ensure an accurate resistance reading, do not touch the resistor or leads during testing.

  1. Cut the output wire from the door lock switch/key cylinder in half,
  2. Test with the meter from the switch side of the cut door lock switch/key cylinder wire to a reliable ground source. Some good ground references are the ground input source to the door lock switch/key cylinder, or the battery ground.
  3. Operate the door lock switch/key cylinder in both directions to determine the resistor values. If the multimeter displays zero resistance in one direction, no resistor is needed for that direction.
  4. Once the resistor value(s) is determined, refer to the wiring diagram for proper wiring.

Manual for releasing the steering lock:

  1. Please check whether there is a steering lock in your vehicle or not, if yes, follow with the next step.

  2. Copy a key blade with your factory’s original key blade and match them so that the copied key blade can start the car.

  3. When finished matched, put the copied key blade into the ignition cylinder of the car, as the picture shows:
    Method 1: turn the key to the “ON” position. **




    ****So that the steering lock can be turned around. Then cut and keep 1mm length of the copied key outside of the lock. See the picture:

  4. Stick the push start button on the lock. (That is the reason for cutting the key.)

  5. Attention: If there is a chip immobilizer in the factory’s original key or remote control, need to take out the chip immobilizer and hide it inside or near the ignition cylinder. Please refer to the installation of the chip immobilizer. If you can’t find the chip by yourself. Just hide the original key or remote control in or near the ignition cylinder. (Please remember to take out the battery of the remote if you do so).

  6. Everything finished like the picture:

  7. If you don’t want to cut the key for releasing the steering lock, you can drill a hole in the car near the steering and install the push start button like in the picture, but it will not convenient for you as you need to use the original key to release the steering lock every time you start the car.

  8. Unplug the factory ignition wire harness to avoid which consume the vehicle battery power.

Method 2: Use a screwdriver and push it into the hole of the ignition cylinder (see photo on the left), turn the ignition key to ACC position, then pull out the key with force will take out the ignition cylinder. Then remove wires from the ignition switch and put the push start button over the empty key cylinder slot.
Important:
Only a qualified staff can do this as there is a risk to lock the steering lock again if the operation is not correct. If you are not a qualified staff, we recommend you to use method 1 to release the steering lock.

Installation of chip immobilizer

If there is a chip immobilizer in the original key fobs, please follow with below method
Method 1:

  1. Take out the original induction coil from the ignition lock.
  2. Put the car’s original remote control (including the chip immobilizer) into the coil, and make sure the induction of the chip immobilizer and the coil are good.

Method 2:

  1. Take out the chip immobilizer from the car OEM remote control.

  2. Take out the original induction coil from the ignition lock.

  3. Stick the chip immobilizer on the induction of the car coil, and make sure the induction of the chip and coil is good.
    Reminder: Some chips with a weak signal are hard to start the car when put on the car’s original coil. Then need to add a coin or other metal pad underneath the chip to enlarge the signal of it (see above drawing)
    Method 3:
    Use an extra bypass module to bypass it, installation steps are as below:

  4. Put the whole remote control (take out the battery from the remote first) and include the chip immobilizer into the bypass module.
    Note: if the size of the remote control is big, the user can put PCB or chip inside the bypass module.

  5. Taping induction wires 2-3 circles on the ignition lock header

Important: Please fix the car OEM remote control and induction wire well around the ignition lock header to make sure the car can be started.

FAQs of EC003N

Dear Customer,
Thank you for purchasing this product. Here are some FAQs for your reference, if there is any question about the products, we recommend you to read the FAQs to find answers and solutions. If those FAQs are still not able to help you fix the problem, you can also contact EASYGUARD LTD and we will help you till everything is working well.

  1. The car lock and unlock randomly, what is the reason?
    This should be due to there being PKE induction blind area and cause the device unable to detect the PKE signal well, the solution is to adjust the PKE antenna placed position till you have a maximum PKE induction range. When placing the PKE antenna, make sure it is not touched by any metal products.

  2. When using the remote start function to start the vehicle, it keeps cranking, what’s the reason?
    It should be due to the fuel pump wire not being well connected, which should connect with the fuel pump wire or oil path motor or sucker wire in the vehicle if you can’t find this wire in the vehicle. You can connect it with the tachometer wire or ignition 1 wire.

  3. When I attempt to start the vehicle, It starts but shuts off a few seconds, what’s the reason?
    There are possible 3 reasons:
    a. If there is a chip immobilizer in your car’s OEM key fob, you need to have an OEM key & also need to buy an extra bypass module in order to make the kits work well. you can buy it from the EASYGUARD sales rep if you need it.
    If you don’t want to buy the bypass module, please take out the chip immobilizer from the car OEM key fobs and stick it somewhere around the ignition cylinder till you can start the car.
    b. The fuel pump wire is not well connected, which should connect with the fuel pump wire or oil path motor or sucker wire in the vehicle, if you can’t find this wire in the vehicle. You can connect it with the tachometer wire or ignition 1 wire.
    c. The engine starting/cranking time is not enough. If so, you need to prolong the start time. Refer to parameter prolong setting instruction in the user manual.

  4. Does the alarm with anti-hijacking function?
    Yes, the alarm default is with the anti-hijacking function.

  5. How to do programming?
    Please refer to the programming method in the user manual.

  6. Is there a GWR (ground while running) wire? Or how to connect with a GWR wire to the alarm?
