Reset battery but 1st get a code saver that pushes into lighter plug Easy and it saves radio code- also try it no recoding Easy to use


The valves inside the charcoal canisters are prone to debris preventing a full seal. I replace these on various older toyota models. Using non toyota parts may make lights go out, but likely will come back within a year or two. they cost more but if they last 10+years the first time, they are worth it.
