Volkswagen Gore motor with out idling

A mileage in excess of 200,000 km of 2004 Shanghai Volkswagen the Gore cars. The proprietors mentioned: no idling the engine after the motor vehicle, stepping on the accelerator Ford VCM pedal to forward only are living automobile. The car air con electromagnetic clutch will pull the air conditioning to operate, run the air conditioner switch would not do the job, the air-con can not be turned off, and also the air-conditioning swap, no the traditional electrical power indicator.

Diagnosis: Initial, test if no idling, using the ignition timing gun proofing ignition timing when it X431 is identified which the the premature ignition time returned to standard, following the adjustment of the ignition time, idling.

Check the air con can not be shut down, plug in decoder to see the data stream on the engine Launch X431system, Group 19, District two, you could see there have been air-conditioned open up signal. Suspected harm to the air conditioning swap, and unplug it to remove the air-con switch, continue to not able to disconnect the air-con compressor electromagnetic clutch, and afterwards notice the air conditioning auto diagnostic tools switch knowledge items within a information stream, continues to be open up state, indicating that this car or truck failure just isn't brought on from the air-con switch, probably somewhere in the line there may be a brief circuit fault.

Check the knowledge learned inside the cab with the central distribution box on a relay will be the air con fan relay, to unplug air conditioning admirer relay, air conditioning compressor electromagnetic clutch disconnect notice this relay auto code reader committed relay of the ordinary five-foot relay, and not a Volkswagen motor vehicle, marked within the drawing this relay inner electronic factors, this relay is just an easy, normal relay, it really is believed in comparison to the car's Following appliances, artificially set up improper, the reason for this failure.

Original motor vehicle relay can not uncover it, can not purchase a new relay, and Al Gore are certainly not a lot of autos within our regional, even though they know the relay amount, believed not necessarily be able to buy, proprietors eager auto, in accordance for the concepts of analysis, everyday relays auto diagnostic tool could be attained through the simple transformation after the manage features of the authentic car, which we use a relay with two diodes in addition to a relay as an alternative to the initial car or truck proven in Figure 2-11, in accordance on the principle of study feasible.
