GENERAL INFORMATION

Since March, 1984 (a code of date of production of "EA") the safety lock of the engine of a screen wiper of a windshield with a current of 15 is entered And (instead of earlier established on 10 A).

The main block of safety locks and the relay is located in a back part of a compartment of the engine on the left side.


Additional safety locks are in a box under the forward panel on the right side (between a middle part of the forward panel and a ware box) and it:

  – N32 safety lock (15 A – yellow) – the probe lambda;
  – N35 safety lock (1 A – black) – the electronic actuation device (cars with the catalyst).

Besides on separate wires of electric food the following safety locks are located:

  – the main safety lock (apprx. 55 A) – on a wire (+) the accumulator;
  – the on-board computer (1 A) – under an instrument guard;
