Diagnostics of the YaMZ-650 engine. Fault codes

To diagnose the YaMZ-650 engine, you need diagnostic equipment from BOSCH of the KTS family (KTS 530/540/570), shown in Fig. 1

In combination with a personal computer, KTZ 5-series modules form a universal system tester (scanner) that works with any electronic vehicle control systems (engine management system, automatic transmission, ABS, airbag, etc.).

The widest range of brands and models of cars (not only with YaMZ-650 engines) with which the device works is determined by the ESI[tronic] software product that ensures its operation.

The module is directly connected to the vehicle diagnostic connector using an adapter cable.

The control unit is automatically recognized and the actual values, error memory and other specific data are read.

KTS 530 is equipped with a multimeter for measuring voltage, resistance and current, and is also equipped with a built-in replaceable ISO-CAN adapter for automatic rewiring of the diagnostic block and a 4-pole OBD adapter.

The KTS 540 module is similar to the KTS 530 device, but can exchange data with a computer not only via a USB cable, but also via a Bluetooth radio channel.

KTS 570, which has all the advantages of the KTZ 540 module, is equipped with an advanced two-channel multimeter and oscilloscope.
