       PREVENTIONS
Checks carry out on conclusions of a block of the socket of the controler. Thus the plug socket should be disconnected from the controler. During carrying out measurements plug sockets of checked elements should not be disconnected.
Checks carry out at the connected socket of the controler with use of the transitional block connected consistently between the controler and its shtekerny socket.


After end of a cycle of check switch off ignition.
