General information:
The idle economizer control unit (IECU) 5013.3761 is purposed
for switching on/off of idle economizer electromagnetic valve
in order to increase saving of fuel and reduce toxicity of
vehicle exhaust gases.
The idle economizer control unit (IECU) 5013.3761 is produced
in a single climatic design О2.1 in accordance with GOST 15150
for internal market and for export. An operating mode of the
unit, in accordance with GOST 3940 is continuous nominal S1.
Applicability: automobiles VAZ-2104, VAZ-2105, VAZ-2107, VAZ-2121 and others.
The idle economizer control unit (IECU) 5013.3761 ensures:
- control of the idle economizer electromagnetic valve;
-
protection*
of the idle economizer valve control circuit
from a short-circuit on "mass" of the vehicle;
-
protection*
from resistance reduction of idle economizer
valve circuit;
The unit 5013.3761 is mounted on a stipulated for it place
in the vehicle with the help of standard fastenings and a
standard plug.
The warranty period of exploitation is 3 years from the date of commissioning or from
the date of sale in retail commercial network. The warranty obligations of the
manufacturer are valid during 4 years from the date of the item production. The date of
production is marked on the item housing.
