Mini car radiator cooling fan manufacturer to tell you the advantage of the Volkswagen stepless speed regulation cooling cooling fan characteristics
the micro motor cooling fan manufacturer small make up to tell you when G62, G83, G65 fails, G62 and G83 reflects the temperature difference is too large, Such as thermostat damage, and blockage of the cooling fan, etc. ) , as well as between J293 and J220 duty ratio signal failure ( Short circuit or open circuit) When the cooling fan will enter a state of emergency operation, with low speed or high speed often turn, but only if the ignition switch to keep on state. So if after turned on the ignition switch, a cooling fan is often turn, micro motor cooling fan manufacturer small make up can tell you from the above several aspects, but if after starting the engine, a cooling fan is often at high speed, you can check the air flow sensor signal is normal.
the micro motor cooling fan manufacturer small make up tell you under normal circumstances, after switch on the ignition switch to the J293 J220 signal is approximately a 9% duty cycle, the cooling fan is not running, Engine work, according to J220 G62 and G83 G65 signal signal 10% ~ 90% of the duty ratio, the cooling fan is low speed or high speed, the greater the duty ratio signal, the faster the cooling fan speed. Under the condition of the ignition switch, if J293 lines appear with J220 cut-off, of iron or electric short circuit phenomenon, J293 will control the cooling fan at high speed.
in addition, if the 15th on the J293 have electricity power cord in the ignition switch is turned off ( Relay terminal short-circuit or adhesion of related circuit for power supply short circuit) And a cooling fan will continue to work after the lock the car, until the battery lost electricity.
in short cooling fan manufacturer of micro and subcompact cars small make up telling you this kind of stepless speed regulation cooling fan has been widely used in soar team, magotan, lavida, passat, skoda, such as cars, if the maintenance personnel can correctly distinguish the above lead to the cooling fan often turn conditions, so in the diagnosis of this kind of stepless speed regulation cooling fan type often turn failure will be.
