In this video it will be a question about preliminary treatment on the K-line and the CAN tire.
The K-line is roughly speaking the conductor through which the diagnostic adapter is connected and on which there is a reading and data recording in engine EBU.
As a rule this conductor connects EBU with preliminary treatment pad through an immobilizer. The immobilizer uses this contact piece for communication with EBU too.
For preliminary treatment on the K-line of rather ordinary KKL adapter, cheapest for preliminary treatment of a car the hands.
The CAN tire as it is already visible from the name is not one conductor, and a little. The CAN tire found use in cars due to increase in them electronic blocks for steering of various gears.
It serves for combination of all these blocks in one system that they could communicate among themselves and transfer each other necessary information.
It is possible to carry to such blocks: Engine EBU, automatic transmission control package, control package climate control, ABS control package and many others.
For such CAN blocks the tire also serves as binding thread. On it they communicate and on it we carry out preliminary treatment. She to us allows to watch at connection to a pad of preliminary treatment parameters not only EBU of the engine, but also other control packages which it unites. Of course if it is supported by the program of preliminary treatment which we use.
For preliminary treatment on the CAN KKL tire of the adapter it is already not enough. In this case from the budgetary adapters we can use, for example, ELM327. This adapter supports preliminary treatment on the CAN tire.
On it for today all!
