CEI and TC Off lights

So I’ve been having an issue with the CEI and TC Off lights being on and my truck being in limp mode. I’ve done some research and found that the Hewitt-Tech SAIS kit should fix that. So I ordered it, installed it and had the battery disconnected throughout the process and when I reconnected the battery and started the truck the lights came back in and it’s still in limo mode…

Is there a certain amount of time that I should drive/let the truck run to see if it will reset or is it supposed to be immediate???

Could definitely use some advice on this….

 

Welcome from LA (Lower Alabama)! I would think that the disconnected battery would have reset those codes. It sounds like something else is going on.

You will get a lot more response (and likely better responses) if you post this question to the Ask the Toyota Mechanic thread or in the 2nd Gen forum:
