Q: How to inspect the cruise control system and Cruise Control Module?
A: The inspection procedure for the cruise control system involves several steps. Firstly, the system consists of a vacuum actuated servo or an electronically operated cable and module located in the engine compartment, connected to the throttle linkage by a cable. It also includes the electronic control module, brake switch, control switches, a relay, the vehicle speed sensor, and associated wiring. To locate common cruise control problems, the following general procedures can be followed. Firstly, check the fuse and ensure it is functioning properly. Then, have an assistant operate the brake lights while checking their operation, as voltage from the brake light switch deactivates the cruise control. If the brake lights do not come on or do not shut off, correct the problem and retest the cruise control. Inspect the cable linkage between the cruise control actuator and the throttle linkage, and visually inspect the wires connected to the cruise control actuator for any damage or broken wires. The vehicle speed sensor, located on the transmission extension housing on 2WD models and on the transfer case on 4WD models, should also be inspected. Finally, test drive the vehicle to determine if the cruise control is now working.
