Replacing this ECM fixed the short through it (no start; P1682; when engine controls ignition relay was closed, ECM fuse popped). Requires programming with J2534 interface (eg VXDiag) and ACDelco TDS SPS (currently $40/VIN/2 years).

This part did not work. The mechanic replaced the old ECM with this one and my engine wouldn't even turn on. When they put my old ECM back in the engine turned on. I believe this part was defective and I'm returning it.

Al programar la computadora no se pudo porgrmar la llave hasta realizar un bypass y quedó permanente la luz de seguridad encendida, es lo único mal. Pero es funcional la computadora, no es grato con una luz, no es como lo esperaba al comprar este producto.
