The computer on my tundra does not start I drove like more than 200 miles
and I took it to the smog and they said that is not ready yet, how much more
do I have to drive ? Thanks
OBD not ready. Just drive the vehicle for about a week or so in a normal way or you can also perform a "drive cycle" (ask Toyota dealer how to do this). The best time to drive cycle your truck is when there is no traffic around 1:00 AM. If it's too much traffic you cannot perform it properly. You may have to do it more than once if the first time failed. You need an scan tool to check if OBD ready after performing the task.
