This E.C.M. fits the following: 2005-2007 3.6L Buick Lacrosse. This auction is for one service number (12592124, 12581144, 19260507, these are all interchangeable) ECM (Engine control module) that is programmed for your vehicle using your V.I.N. (Vehicle identification number) to exactly match your vehicle. The service numbers listed are interchangeable when the computer is reprogrammed.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 module has by far the highest failure rate of any we sell. For that reason we live test each of these computers by programming and installing the ECM on our 2004 Rendezvous 3.6 liter test vehicle. This ensures that the unit works properly with no codes, misfires or gauge malfunctions. We are the only seller of these modules that does this.This ensures that you will receive a good ECM. There is no core charge you keep your old E.C.M. There is a 90 day warranty. An anti-theft relearn will have to be performed before the vehicle will start. This is something that does not require tools except that a battery charger or jumper cables from another vehicle should be connected to keep the battery up because the key will be on for over 1/2 hour. Specific instructions will be in the box with the computer. We will ship within one business day of payment. Same day shipping if ordered by 2:00 P.M. EST (Mon. – Fri.)
