4.13.5. KSUD self-diagnostics

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 in a combination of devices is for this purpose used.
For transition to a mode of self-diagnostics turn the ignition key in the situation "ON". Thus in a combination of devices the yellow indicator of malfunction of KSUD should light up. Start up the engine. Through 2 — 3 about the indicator should go out that means lack of malfunctions in system. If the indicator does not die away, execute the following actions:
— switch off ignition;

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


— put a wire crossing point between "SNK" and «IGN» conclusions on diagnostics block (fig. 2.94);
— through 2 with remove a crossing point.
The control lamp will start to blink, displaying a conditional code the malfunctions fixed by the controler. 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
Malfunction place
11
Sensor of provision of a camshaft and frequency of rotation of the engine
12
Measuring instrument of a mass consumption of air
13
The sensor of temperature of cooling liquid
21
Violation of work of a subsystem of management by 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.
