I dropped by the Ford dealership that has my car now and gave the service manager printouts of your and Frankie's suggestions. He told me the line to Ford or their website or something was down yesterday and he will give the hints to the mechanic. Yesterday, the mechanic got an error code indicating something regarding the instrument cluster. The mechanic will get back on it when he can get back in touch with what I think is Ford's help line.According to the Ford Workshop manual, the PATS is controlled by the instrument cluster, which then tells the
PCM whether to start the engine.
There is an built in antenna around the ignition key switch which reads the transponder chip in the ignition key.
When you insert the ignition key, turn key on, but do not start car, see what the instrument cluster does, do the
gauges, and idiot lights light up?
While I was there, I asked the parts manager if a new FEM was available for my car. I fear that Midwest Tec Mart screwed mine up and I might need to get a new unit, if possible. He checked my VIN and gave me part number 1W6Z14B205AA but none are available. (Some seem to be available online.) The one in my car is part number 1W6T13B525AJ. Is the new number a replacement?
