Principle of functioning and check of the central lock and system of opening of doors without a key

The central lock puts in action actuation mechanisms of locks of each of doors. The system consists of switches, actuation mechanisms, the relay and connecting conducting. Diagnostics of malfunctions of system is usually limited to the elementary checks of a condition of contacts of conducting and actuation mechanisms during which performance repair insignificant can be made and it is easy устранимых damages.

Management of a drive of the central lock is usually carried out by means of the bipolar electromagnets placed in the doorway of the car. Lock switches can be established in one or the other positions - Is closed and is opened. Switching of the given switches leads to activation of the relay connecting a food to electromagnets of blocking of doors. Depending on a way of inclusion of the relay polarity of pressure varies, providing respective change of position of a latch of the lock.

Some models can be equipped by the anticreeping system which has been built in the scheme of the central lock. If you do not manage to reveal independently a cause of a failure by carrying out of some the general checks, address for consultation in dealer branch of company Chrysler.

 PERFORMANCE ORDER

  1. Always first of all check chain protection. On the given models a food from the battery moves in system through a minisafety lock on 20 And (F-1), located in РDС in an impellent compartment and 15 And a safety lock (№ 8) in the assembly block.
  2. At the switched off engine попереключайте switches of locks of doors in both directions (it is opened - Is closed). Relays thus should publish well distinguishable clicks.

Site of the relay of locks of a door.

  1. If clicks are not audible, check up food presence on switches. If a food is absent, check up conducting between switches and the assembly block of safety locks on presence of breakages and short circuit.
  2. If pressure takes place, but relays do not publish clicks, check up conductivity of the switch. If conductivity is absent in both positions of the switch, replace last.
  3. If the switch has serviceable conductivity, but relays do not click, check up integrity of conducting between the relay and the switch. In case of need make regenerative repair or replacement.
  4. If the relay receives alarm pressure from the switch, but does not transfer a command to electromagnets, whether check up grounding of the case of the relay is broken, in case of need replace the relay.
  5. If all electromagnets except one function, remove the panel of an internal upholstery of a corresponding door (the Head the Body) whether check up a food on a magnet moves at switch switchings. On one of wires pressure should be present at switch position Is closed, on other - at position is opened.
  6. If pressure takes place, replace an electromagnet.
  7. If pressure is absent, check up conducting between an electromagnet and the relay on presence of breakages and short circuit.

Conducting is in the habit to fray on a site between a body and a door (during opening-closing of last).

System of opening of a door without a key

The system consists of the remote block of management (radiator) which sends the coded signal in an infra-red range on the receiver located in the top (ceiling) console or the case of the fixture and includes a drive of the central lock.

 PERFORMANCE ORDER

  1. Make replacement of batteries of a radiator at refusal of inclusion of a light-emitting diode on a wall of its case at нажимании buttons.
  2. Halves of the case of a radiator can be divided cautiously having hooked their screw-driver.
  1. For division of halves of the case of the remote block of management by the door lock take advantage of a screw-driver.
  1. Replace two литиевые batteries of type СR1616 with pressure 3 In everyone.
  1. Replace литиевые batteries (arrow).
  1. Densely compress halves of the case of a radiator.
