Blair Hong Posted June 23, 2014 Report Posted June 23, 2014 My car is overheating and I believe that the fan isn't engaging. I've tested the relay and appears to be working fine. So I think the ECU isn't I/O for the fan isn't working anymore. Is there a way to test for the fault? I've got an old Link Plus. Cheers Quote
Simon Posted June 23, 2014 Report Posted June 23, 2014 No test function on the old ones. One option is to lower the fan temp to below the current engine temp and see if the fan come on. Quote
