How can you reprogram the ccm?

Answer 1

Trickey one. simple answer is not by yourself. computer modules on cars can be reprogramed with the right equipment (laptop and connector/factory scan tool, and a battery saver and internet connection) but is usually done only at a dealer. some shops might be willing to reprogram but it usually hit or miss. The problem with reprogramming computer modules is you have to have constant power to the car (thus the need for a battery saver) as the reprogramming can last for hours, even overnight. If the vehicle's battery dies during the reprogramming, the computer module becomes a very expensive paperweight.

On the brighter side, some parts dealers may sell new computer modules that are already pre-programed so you wont have to worry about it again.
