Chrysler Repair: 1993 Chrysler Concord Fault 77, chrysler concord, crank sensor

Question
Hello Roland,

Thanks for the great start on fixing the trap codes of my buddies car. He has the codes

12- disconnected battery recently
11- (rotational sensors are codes 11 or 54)
77-
55- end readout

I am unable to locate the 77 code? Any change I can ask you what that means?

Answer
The '94 manual says the 77 indicates a short or open in the speed control relay circuit, but because there is no relay as such I beleive this would refer to the speed control servo circuit.
By the way 11 is for the crank sensor and 54 is for the cam sensor.
