See part numbers at the top of the listing. - . This unit offers a 30
day functionality warranty. As always with this type of component your best bet is to
match the part number to the one on your original ECU. A faulty ECU is
one of the most common no start or random stalling problems with these trucks. these can also cause issues with erroneous check
engine lights, idle control problems as well as emission control &
cold or hot start problems. I have also seen fuel pump relay turn on
faults (ECU won't turn on the fuel pump), as well as an condition where
the high speed injector driver has failed. This causes the car to sit
and idle fine, but it won't accelerate.If your car does not
have these issues but you intend to keep it a while, I recommend our
customers keep an extra ECU in the back. These units now have to be
special ordered from most dealers new for big $$ (often times over
$1000!), and you can never find one when you need one. Even now
finding a good one second hand is getting to be quite difficult as
these cars get older. Toyota made many different typed of these, even in the same year range. You must match your original part number!
