Self-diagnostics system, reading of codes of malfunctionsThe general information
The module of diagnostics is a part TCM and allows to reveal any malfunction connected with refusal in one or several elements of control system АТ. Gauges of speed concern number of such traced elements (VSS 1 and 2), electromagnetic valves of switching 1, 2, 3, And, In and With, the gauge of temperature ATF, the gauge of atmospheric pressure. Besides, under the control there are parametres of power supply systems and ignition.
Reading of codes of malfunctions by means of a control lamp
Address also to the Specification of the Head of the Control system of the engine.
The self-diagnostics system notifies the driver on results of the activity by means of a control lamp. So, a periodic blinking of a control lamp with frequency of 4 Hz (4 gleams in a second) testify to malfunction of the power supply (the storage battery). The blinking with frequency of 2 Hz testifies to absence of refusals.
At entering in memory of the module of self-diagnostics of codes of malfunctions it is enough to count quantity of gleams of a control lamp.
Continuous burning of a lamp testifies to refusal of the gauge-switch of position of the lever of a choice of ranges, the manual switch, the gauge of completeness of closing throttle заслонки or элетропроводки corresponding chains.
The lamp starts to blink at the moment of engine start. Process выcandlesивания codes occurs unitary (Address to Section Problem diagnostics АТ - the general information and to Specifications of the Head of the Control system of the engine).
Reading of codes of malfunctions by means of the scanner
Reading brought in memory of the module of self-diagnostics of codes can be made also by means of the special scanner (the Section System of onboard diagnostics (OBD see) - a principle of functioning and codes of malfunctions. Signals in chains of management of the Head of the Control system of the engine). The socket for scanner connection is located under the panel of devices. The list of codes is presented in Specifications of the Head of the Control system by the engine.
The given function allows to keep working capacity of a vehicle in case of failure of the gauge of speed, the gauge of position throttle заслонки (TPS), the gauge of position of the lever of a choice of ranges, and also any of electromagnetic valves of switching.
The gauge of speed. In a control system the duplicating gauge of speed is used. The core is placed in картер transmissions the gauge, duplicating is included in a speedometer drive.
The gauge of position throttle заслонки. At refusal TPS throttle заслонка it is established in some average position providing adequate functioning of the engine and transmission.
The gauge of position of the lever of a choice of ranges АТ. If gauge refusal is connected with occurrence of a duplicating signal, transmission will be switched with a following priority: D N () 3 2 1.
Electromagnetic valves 1 and 2. At refusal of one of the given electromagnetic valves both of them are translated in a mode of Vykl (OFF) that corresponds to transmission transfer in position “3”. In default both valves transmission is translated in a mode of use of a mechanical hydrodrive.
The electromagnetic valve 3. At failure of the electromagnetic valve муфты braking by the engine it is automatically translated in position OFF that corresponds to inclusion of a mode of braking by the engine.
Refusal of the given valve it also passes A.Pri's electromagnetic valve in position OFF that leads to pressure lifting in the basic highway to the maximum value.
The electromagnetic valve of Century the Given valve in default also is translated in position OFF that leads to deenergizing of blocking of the hydrotransformer.
S.Otkaz's electromagnetic valve of the given valve leads to constant inclusion of a full drive.
