Principle of action and check of serviceability of the electric drive of change of provision of seats

The special electric drive allows to regulate the provision of seats by very insignificant effort. These models are equipped with the seats having six degrees of freedom and capable to move respectively back and forth, up-down, and also to bend forward and back. Seats are equipped three reverse types with the motors placed in the general casing and operated by the switches fixed sideways on a seat. Each of switches serves for change of polarity on the motor, respectively defining the direction of shift or an inclination of a seat.

Diagnostics of malfunctions of the electric drive is rather simple and is performed by implementation of the procedures described below.

 PERFORMANCE ORDER

  1. Glance under a seat in search of the object gone there capable to interfere with movement of a seat.
  2. If the electric drive of a seat does not function in general, check a condition of the breaker of a chain for 30 A (No. 25) in the assembly block of safety locks.
  3. Having switched off for the purpose of decrease in a noise background the engine, a popereklyuchayta in both directions seat drive switches, listening to the sounds made by drive motors.
  4. If the motor does not function or publishes unusual noise, check tension on it until the assistant switches the switch.
  5. If food on the motor moves, but it does not rotate, remove it from the car and check, giving power supply directly from the battery. If turning on of the motor does not happen and now, replace it.
  6. If food is absent, remove the switch and check it. If tension on the switch is absent, check a condition of an electrical wiring between the switch and the assembly block of safety locks. If tension takes place on a red wire of the switch, check a condition of the breaker of a chain. Check a black wire and, in case of lack of its conductivity, replace the switch. If the switch as it should be, check conducting between it and the motor for existence of breaks or short circuit.
  7. Repeat check of functioning of the drive after introduction of the corresponding corrections.
