The starter solenoid on the 2006 Honda Odyssey is connected to the starter motor and base. In general, when replacing the starter solenoid, the starter motor also is replaced as one whole assembly. The starter is mounted to the top of the transmission case and can be accessed from the topside of the engine compartment. To access the starter, you must remove the battery and battery tray. Before the battery is disconnected, retrieve the radio security code from the owner's manual or from "radio-navicode.honda.com".
Lift the vehicle hood and support it with the hood prop rod. Ensure you have the radio security code before continuing. Document the radio presets on a piece of paper. If you do not have the radio security code, Honda offers an online code retrieval system, using your vehicle identification number, personal data -- phone number and ZIP code -- and the radio's serial number.
