This auction is for one service number 12581565 ECM (Engine control module) that is programmed for your vehicle using your V.I.N. (Vehicle identification number) to exactly
match your vehicle. After you purchase the E.C.M. you will need to provide us with your V.I.N so that
we can program the E.C.M. before we ship it to you.
This computer is refurbished and tested for functionality.
There is no core charge you keep your old E.C.M.
There is a one year replacement warranty.
Two things may have to be done after you install your E.C.M. First an anti-theft relearn may have to be
performed. If this is the case the truck will not start.
The second thing is that a crankshaft variation relearn may need to be performed once the vehicle is
running. This will be evident if the check engine or service engine soon light comes on once the vehicle
is running. You will need access to a scan tool capable of doing this procedure to do this and clear any related trouble codes (Code
P0315). If this is not available to you a repair shop will have to perform this and clear the
related trouble code. The vehicle will run normal but the ”service engine soon” light will come on and a
trouble code will be stored until this is resolved.
Instructions for both procedures will be included.
We will ship within one business day of payment.
You can pay instantly with PayPal.
We use Alldatapro for our repair information. If you need diagnostic information please let us know and we can help. We are also a member of IATN (International automotive technicians network) a valuable resource of auto repair information.
***Some other sellers of computers do not disclose that these procedures must be done until you have bought the product---others claim that their units are 100% plug and play. To be 100% plug and play they would have to alter the function of the computers original design and you might lose your antitheft protection and the ability to detect engine misfires. The proper way to replace an engine computer and be sure your vehicle remains in it's original condition is to do both the antitheft relearn and crankshaft variation relearn if applicable.***
Same day shipping if ordered before 2:00 P.M. EST (Mon. - Fri.)
