    Didn't a Pedal Commander fry an ECU a few years back?

    If it went to the dealer they always say it fried... when in reality only a couple were and the rest are bricked.
    Adding the pedal commander is messing with the electrical of the truck and can fry a ecu... doing a update from ovtune or dealer techstream it gets bricked, very hard to fry that way.

    I thought it literally burned the terminals up on that guys truck or I could be confusing it with something different.

    Wouldn't doubt it in the least.. like I said messing with the electrical and not disconnecting the battery or you cause a short in your work then reconnect battery. These newer trucks have very sensitive electronics... always reading voltage, amps, and resistance. Look how many had issues with switching to LED bulbs with out using diodes to control voltage readings and make sure there is only one direction of flow for power. How many have tapped into the dome light or rear view mirror and have had issues.
    Like half the 3rd gen section is filled with those threads and the like.

    Wouldn't the ECU be covered under the emissions warranty to 80k though? No ECU, no emissions control...

    I thought so too.
    They way i read it, emissions related components(ecu included) are 3yr/36k. California gets 7yr/70k. Only components denoted by "8/80" get that coverage.

    Looking at my truck's manual, looks like it's pretty reasonable to assume the ECM would be covered for 8/80. Kind of a moot point given OPs mileage but at least it is covered for awhile!

    They look Russian Orthodox / Greek Catholic.

    Don't ask me how I know or why I can chug altar wine.

    UPDATE. ————————
    I got it back today. Toyota sent a tech in who replaced the ECM. Apparently it is a known problem with Toyota corporate, but no bulletin to the dealers yet. Running great, they checked everything else out and it’s good to go.

    I remember that one well! Eastern Orthodox kind of sticks out in a crowd.
