With the negative terminal disconnected, wait for a sufficient duration, usually around 15 to 25 minutes. during this time, any residual charge within the ecu’s capacitors will dissipate, ensuring a complete reset. after the waiting period, securely place the negative cable back onto the negative terminal post.
Toyota Tundra Ecu Reset Procedure I want to know this because i don't think you can "reset the computer". as a previous post says , disconnecting the battery does not erase any codes set in the computer. you need a code reader to do that. and then the code will reset if the problem is not cured. (the most common code is for emission system problem when you don't tighten the gas. Generally, the only reason to hard "reset" the ecu is to account for major intake exhaust changes outside of the ecu's typical map, i.e. installation of a piggyback controller, supercharger, etc. even then, the ecu will "learn" to account for the operating environment in about 100 150 miles on its own anyway.

No need to go to the dealer. removing power from the ecu resets everything to default values, like fuel trims. that can be accomplished two ways. 1) disconnect the battery positive cable for a bit and reconnect it. 2) pull and reseat the efi fuse in the fuse block under the hood. this is easier, and doesn’t cause the radio to lose its presets.
