Afternoon all - I have to replace a couple of instrument panel bulbs in the wifes 2003 Odyssey this weekend. I have a Haynes manual for instructions but it recommends to disconnect the battery before I start working. It then also lists a couple of procedures that "may" have to be done when the battery is reconnected - "radio security code, engine management to re-learn idle paterns" etc. What are the risks to not disconnecting the battery - is it possible to get it done without having to disconnect?

Thanks,
Pieter
