The operation of systems and units of modern cars directly depends on the correct operation of the “think tank”, called the electronic control unit (ECU), aka Powertrain Control Module (PCM). Malfunctions in the electronic unit are immediately reflected in the operation of the power supply, transmission, exhaust system and other elements.

Complex equipment is required to check the operability of the control unit.only a specialized service center can perform such testing.
