The Pontiac Fiero is a mid-engined sports car that was built by the Pontiac division of General Motors from 1984 to 1988. The following article is about troubleshooting Pontiac Fiero Cruise Control System written by Oliver Scholz.

The Fiero used two fundamentally different approaches to the cruise control. The 1984 – 1986 4 cylinders and all V6 Fieros use a separate cruise control module. It is located behind the carpet on the driver side center console. The second system involves the 1987 – 1988 4 cylinder Fieros with DIS. On this cars, the ECM takes care of the cruise control functions. The advantage is that you can troubleshoot the system with scantool.

The cruise control module (or ECM) is fed an electrical signal from the speedometer, telling it the current speed. It has a couple of switches telling the module whether it should keep the current speed, accelerate or decelerate, or switch off.
