A significant part of the malfunctions in the engine control system occurs due to a violation of the switching conditions for the peripheral devices of the system and the control unit. These violations are contact violations or unintended short circuits. Using the wiring diagrams in this manual, the layout of the connector pins, you can use an ordinary tester to check the wiring.
In addition, a number of peripheral devices can be checked with an ohmmeter.
We do not provide methods of working with special diagnostic testers in this manual, since all the necessary control actions are included in the software of these testing devices (or described in the instructions for the devices).
