Diagnostics of electric components and reading of codes of malfunctions

THE GENERAL DATA


The system of electronic control by transmission consists of the management block (ТСМ), located under a back seat, electromagnets of management, various gauges and gauges-switches.

If ТСМ reveals malfunctions in management chains, it bring them in memory. For reading of codes electronic tester VAG 1551 with adapter VAG 1551/3 is used.

The remark: All information on reading of codes contains in a tester.

Revealing of malfunctions is alternative can be made by measurement of values of resistance and pressure by means of tester VAG 1598/18 (Address to tables).

Check of pressure is made without switching-off of the storage battery, - the tester is connected to ТСМ and its electroconducting. At check of resistance disconnect a negative wire from the battery and connect a tester to a plait of electroconducting ТСМ. ТСМ leave disconnected.

At malfunction revealing it is necessary to make repair of electroconducting or a corresponding element of a chain.
If everything is all right, hence, it is damaged actually ТСМ.
