Symptom: a 2009 output in the Ford Mondeo sedan ( fitted 2.3L motor and 6-speed handbook transmission ) , the gathered mileage of autologic about seventy two,000 km, the engine stalled owing towards the cooling admirer has higher pace and into your plant maintenance.

Troubleshooting : It mirrored the driver , the vehicle once the ignition change is turned on , high-speed cooling lover has actually been frequently convert . To start with xprog-m confirm malfunction. Following the motor flameout notice the working of your cooling admirer , and indeed because the consumer claimed , often switch high-speed cooling supporter continues to be retained . IDS detection without any fault code stored . Analyze feasible explanations are: cooling lover failure ; admirer handle module failure ; pertinent line failure ; PCM failure.

Because the cooling enthusiast is managed via the PCM successful vehicle based upon pulse signal conditioning . So first make full use of IDS community tests , PCM, TCM and KVM ( keyless manage module ) module communication is regular, the flame for a long time after viewing the data stream with IDS, revealed in Figure 1 , the data circulation shows the coolant temperature is sixty nine, air con tension of 813 kPa, evidently doesn't need a cooling enthusiast function, as well as cooling lover PCM pulse width modulation is also zero , indicating that PCM can also be demanded within the cooling lover stopped state , but this time was in large velocity cooling admirer . IDS for making use of active cooling enthusiast check and located that its pace would not range with modifications within the regulation of PCM takes place , indicating which the cooling lover will not be PCM management ( Figure 2 ) . Cooling admirer wire connector has 3 lines , that are grounding strains, power traces augocom and sign traces , because the cooling enthusiast managing at large speed , the ability cord and grounding line isn't any problem , and afterwards choose the initiative for making the cooling supporter exam IDS though measuring the signal line width manage in different states with the grounding resistor , the resistance was located in 0.six kn-11 kn adjust, indicating command and sign output PCM 's ordinary , it might be concluded that the failure was triggered by faulty lover handle module the . Troubleshooting: For the reason that there is not any independent source admirer management module , only switch the cooling fan assembly, substitution will yet again make use of its IDS energetic testing , the cooling admirer pace is usually altered with modifications inside the pulse width adjustments , the failure to entirely eradicate .

Troubleshooting: Since there is no individual offer lover management module , only change the cooling fan assembly, substitution will all over again make jma trs-5000 usage of its IDS active screening , the cooling supporter velocity is usually adjusted with modifications during the pulse width adjustments , the failure to absolutely eliminate .
