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 simplest checks of a condition of contacts of conducting and actuation mechanisms during which performance repair of insignificant and easily removable damages can be made.

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. Switches of the lock can be established in one or the other provisions - Are close and openly. Switching of these switches leads to activation of the relay connecting a food to electromagnets of blocking of doors. Depending on a way of turning on of the relay polarity of tension changes, providing respective change of provision of a latch of the lock.

Some models can be equipped with 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 failure by carrying out a number of the general checks, address for consultation in dealer office of the Chrysler company.

 PERFORMANCE ORDER

  1. Always first of all check protection of a chain. On these models a food from the battery moves in system through a mini-safety lock on 20 And (F-1), located in PDC in an impellent compartment and 15 And a safety lock (No. 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.

Location of the relay of locks of a door.

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 If tension takes place, but relays do not publish clicks, check conductivity of the switch.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

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

System of opening of a door without a key

The system consists of the remote control unit (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 lamp 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 a button nazhimaniye.
  2. Halves of the case of a radiator can be divided carefully having hooked them a screw-driver.
  1. For division of halves of the case of the remote control unit by the lock of a door use a screw-driver.
  1. Replace two lithium batteries of the CR1616 type with tension 3 In everyone.
  1. Replace lithium batteries (shooter).
  1. Densely compress halves of the case of a radiator.
