Have Toyota Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose).
Yes you can replace the computer with a used computer that has matching numbers. You will however need to program it and the keys to the vehicle during or after the swap so it will start and run right.
If your confused on what to do now. You have already been charged the full question value. It's now time to compensate the tech that helped you. The only way I can continue to work here and help customers is by getting rated. If your not pleased yet or plan not to rate me. Let me know so I can help more, close the post, or opt out. Please let me know if you are pleased with my help.
Yes you could leave the programming in the PCM that you install and hope for the best as well as attempt a at home immobilizer programming.
With a diagnostic tool, yes.
Some high end aftermarket tools will program but most do not have a link access to Toyota to get the most recent updates released.
You do not have to replace the immobilizer when replacing the computer. It seems there was more to the concerns than you have told me. The question was opened and you asked " Can I replace the computer with a used computer that has the same numbers on it? The van has the engine immobilizer on it."
Was there more to the concern since your now talking about codes and the CMP sensor?
Now that I know more about the concern. I do not believe i can figure out this issue. I will opt out and let another try. You may want to open a new post since the concern now is not the same as the question you asked me.
