4.13.5. Self-diagnostics of KSUD

Possibilities of KSUD allow to define malfunction of the main sensors of system independently. The self-diagnostics mode at which malfunctions are determined by the conditional code transferred by a blinking of the yellow indicator to combinations of devices is for this purpose used.
For transition to the mode of self-diagnostics turn the ignition key in the provision of "ON". At the same time in a combination of devices the yellow indicator of malfunction of KSUD has to light up. Launch the engine. Through 2 — 3 about the indicator has to go out that means lack of malfunctions in system. If the indicator does not die away, perform the following operations:
— switch off ignition;

Fig. 2.94. Installation of a wire crossing point between conclusions of "IGN" and "CHK" on diagnostics block


— put a wire crossing point between conclusions of "SNK" and "IGN" on a block of diagnostics (fig. 2.94);
— through 2 with remove a crossing point.
The control lamp will begin to blink, displaying a conditional code of malfunction, recorded by the controller. At first long flashes transfer number of tens of conditional code, then short — number of units. Codes of malfunction of KSUD are given in tab. 2.14

Table 2.14  Codes of malfunction of KSUD
Malfunction code
Place of malfunction
11
Sensor of position of the camshaft and frequency of rotation of the engine
12
Measuring instrument of a mass consumption of air
13
Sensor of temperature of cooling liquid
21
Violation of work of a subsystem of management of an ignition advancing
34
The detonation sensor (on the SR20DE engine)
43
Sensor of provision of a butterfly valve
55
Malfunctions are absent

After completion of check switch off ignition.
