This is for one service number 12569773 ECM (Engine control module) that is programmed for your vehicle

E.C.M.

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 ca[able 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.
