Search of malfunctions - the general information
At failure detection of automatic transmission first of all check up level ATF (Current leaving and service see the Head). If level is insufficient, estimate a condition of corresponding epiploons. Attentively examine all hoses of path ATF, and also the cooler heat exchanger трансмиссионной liquids and make sure of absence of signs of development of leaks. The only thing that can be still executed forces of the owner of a vehicle, is check/replacement of information gauges of control system АТ. Before to start replacement of the suspected gauge, poll memory of the module of management (TCM), - all a little essential refusals are registered in memory of the module in the form of codes DTC (the list of codes see in Specifications of the Head Automatic transmission).
In case of especially gross infringements TCM automatically switches transmission in functioning emergency operation.
Reading of codes DTC is made by means of the special scanner connected to a socket of system of onboard self-diagnostics (DTC) (see Has undressed Reading of codes DTC, clearing of memory of the processor), - in the absence of access to the necessary equipment will try to define qualitatively at least the refusal nature (at level enough: electric/mechanical) for the purpose of simplification of dialogue with experts of car-care centre. It is not necessary to start removal АТ as its diagnostics is represented possible only in the established position prematurely.
