Re: ABS Light...
You set a code by disconnecting the sensor......this caused the PCM to command the coolant fan on....so you know the circuit to the fan(via the relay) from the PCM is ok.......
As I said before, if you have the vehicle running, and command the A/C on, and the compressor does not engage, that coolant fan may not come on if a pressure sensor is one of the inputs to the PCM.....for example, when the pressure in the system reaches a certain point, then the PCM commands the fan on......if the compressor does not engage, then the fan won't run....
Have you checked for PCM codes? Have you checked hi/lo pressures with a set of gages?
