Cruise Control Module Replacement Cost Estimate

After other components of the cruise control system have been diagnosed as properly functioning, the next cruise control module may be suspected of failure. Diagnosing the cruise control module may require setting with a computerized scanner for some vehicles, or testing of analog voltages to and from the control module. A general way of understanding when a module has failed is when correct inputs do not result in correct outputs.

Replacing any control module, including the cruise control module, requires removing obstruction components to gain access to the control module. The battery must be disconnected prior to removing electrical connections to the cruise control module, as this will prevent any power surging or unintentional grounding of battery current. Finally, the cruise control module fasteners and mounting brackets will be removed so the new module may be installed. Once reassembled, the cruise control module will receive the latest software updates from the manufacturer, and the system will be tested to prove the repair.

When a control module is replaced, the latest software updates for the vehicle should be sought to ensure the most reliable operating scenario for the new module, and the rest of the vehicle. This can eliminate future issues, as updates are only issued to eliminate known or potential issues.

The cruise control system may be disabled even if the system is working properly. This may result from an error in the anti lock brake system or the traction control system. A faulty powertrain or transmission control module may be the cause as well, so testing is mandatory prior to deciding to change the cruise control module.

Technicians undergo extensive classroom and hands on training in able to understand the operation and diagnostics of computerized systems on today's modern vehicles. Not only is extensive knowledge required, but diagnostic equipment which is not economical to purchase for the DIYer is likely required to perform the diagnostics and repair of computerized automotive systems. It is not recommended to attempt diagnosis or repair of the cruise control module unless the proper tooling and skills are present.
