Symptom: a 2009 output on the Ford Mondeo sedan ( equipped 2.3L motor and 6-speed guide transmission ) , the amassed mileage of autologic about 72,000 km, the motor stalled due towards the cooling enthusiast has high speed and in the plant maintenance.
Troubleshooting : It reflected the motive force , the vehicle after the ignition change is turned on , high-speed cooling supporter has been frequently flip . Very first xprog-m confirm malfunction. Following the engine flameout observe the performing of your cooling lover , and in fact given that the purchaser explained , typically turn high-speed cooling lover has actually been retained . IDS detection without having fault code saved . Review attainable factors are: cooling fan failure ; admirer regulate module failure ; applicable line failure ; PCM failure.
Because the cooling admirer is managed with the PCM successful motor vehicle dependant on pulse sign conditioning . So initial make use of IDS community testing , PCM, TCM and KVM ( keyless regulate module ) module interaction is typical, the flame for many years soon after viewing the data stream with IDS, proven in Figure 1 , the info flow exhibits the coolant temperature is 69, air-con pressure of 813 kPa, evidently does not call for a cooling supporter function, as well as the cooling fan PCM pulse width modulation is likewise zero , indicating that PCM is likewise expected within the cooling enthusiast stopped condition , but this time was in substantial pace cooling enthusiast . IDS to create utilization of active cooling lover check and located that its pace does not vary with improvements in the regulation of PCM takes place , indicating the cooling fan is not really PCM regulate ( Figure 2 ) . Cooling lover wire connector has 3 lines , that happen to be grounding lines, power traces augocom and signal lines , for the reason that cooling enthusiast managing at significant pace , the power cord and grounding line is not any difficulty , then choose the initiative for making the cooling enthusiast test IDS though measuring the signal line width command in several states of your grounding resistor , the resistance was located in 0.6 kn-11 kn adjust, indicating handle and signal output PCM 's usual , it may be concluded that the failure was prompted by faulty supporter manage module the . Troubleshooting: Since there is no separate supply lover handle module , only replace the cooling admirer assembly, replacement will again utilize its IDS energetic testing , the cooling fan velocity is usually altered with alterations from the pulse width improvements , the failure to completely remove .
Troubleshooting: Mainly because there is not any independent provide fan handle module , only replace the cooling lover assembly, replacement will again make jma trs-5000 usage of its IDS lively tests , the cooling supporter speed can be modified with improvements within the pulse width adjustments , the failure to absolutely reduce .
