Cruise Control

Most 2003 and later Honda Odyssey vehicles use the Electronic Throttle Body for the Cruise Control, that is commanded by the Power Train control Module. So really there is no Cruise Control unit, it is really part of a software program. If you are having trouble with your Cruise Control, I would first start by having a very good shop scan your Engine Data, not a parts store min-scan. When a good Technician looks at the engine data, they will be able to see whether or not the Cruise Control is signaling the Power Train Computer to enable the Cruise Control function. They will also be able to see if there are any trouble code conditions that would stop the Cruise Control from working, like an ABS Light on, a Check Engine Light, even an Air Bag light can stop the Cruise Control, because say if the Steering Wheel Air Bag is having a problem from a broken clock spring wire ( pretty common ) the systems won't 'hear' and/or 'trust' any commands from the steering wheel or steering column, which by the way, is where the Cruise Control Switches are located.
