5.2.10. Check of work of system of stabilization of idling
Warm up the engine up to the normal working temperature.
Switch off the air conditioning system (if is available).
Completely turn a steering wheel, then check idling rotation frequency. Frequency of rotation of idling has to decrease for a while, and then return immediately to former value. If pressure sensor socket in a steering hydraulic system with the amplifier is connected, check the same, but with the disconnected socket. Instant decrease in frequency of rotation of idling has to be less at the connected sensor.
