       PREVENTIONS
You carry out inspections on controller socket block conclusions. At the same time the plug socket has to be disconnected from the controller. During measurements plug sockets of the checked elements should not be disconnected.
You carry out inspections at the connected controller socket with use of the transitional block connected consistently between the controller and its shtekerny socket.


After end of a cycle of check switch off ignition.
