Is Your Vehicle Plagued by Mysterious Electrical Gremlins?
If you’re dealing with a persistent check engine light, rough running conditions, stalling, or a vehicle that simply won’t start, a failing Engine Control Module (ECM) is a very likely cause.

This fully programmed 12602044 ECM is your direct-fit, hassle-free solution to get your vehicle back on the road and running like it should.

An Expert’s Note on Programming
As a technician, I’ve seen countless vehicle owners try to save a few dollars by installing a used, un-programmed ECM from a salvage yard. This almost always ends in frustration.
