1994 Ford Bronco EEC IV codes

Please help! I have a 1994 Ford Bronco with 285,000. miles. I pulled the EEC IV codes with the help of way2old and Jim one of which I could figure out but the rest are a little more complicated can anyone help me? Ok #632 overdrive cancel switch not changing states (E-40D) next #538 system did not recive "goose" test or operator error or insufficent RPM range during KOER dynamic response test. next #536 Brake on/off circuit failure. switch not actuated during KOER test. and one more #116 engine coolant sensor (ECT) out of range. The truck is hard to start warm, i have to put the gas peddle to the floor to start it hot, at cold start it idles fine when it warms up it idles high (1300 RPMs) . any help would be appriciated.

I think we got her, I followed your directions to the T, let me back up first I changed the ECT sensor $24.00, its never been replaced, fixed a heater hose that I found leaking then fired her up. I warmed the vehicle up to operating temp. ran the codes ( it went into a high idle again) so i ran it for awhile, took a drive came back the truck idled great, I could rev up the engine and it would drop right to the normal idle RPM's. Ok I ran the codes again and the only code that came up was 538 so I went thru the sequence again that you told me and still only the 538. Way2old its running great I can shut it off hot and it will start up just like new, after driving the high idle seems to have gone away. So I will run it this week and at weekend I will run the codes again and if the 538 comes back I will be it touch. I wanted also to say "thank you" for your help it has made my job alot easier and save me alot of money.
