NEW Pre-Programmed Fuel Injector Control Modules (FICM)
2001 - 2004 LB7 GM/GMC/Chevy Duramax Diesel (8th digit of VIN=1)
The FICM (Fuel Injector Control Module) controls the electrical impulses that control the Bosch common rail injectors. When a fuel injector circuit fault condition is detected by the fuel injector control module, all of the fuel injectors on the affected ignition voltage circuit will be disabled. If a circuit fault condition is detected on a fuel injector circuit for cylinders 1, 4, 6, or 7, then DTCs P0201, P0204, P0206, P0207 will set along with DTC P1261. If a circuit fault condition is detected on a fuel injector circuit for cylinders 2, 3, 5, or 8, then DTCs P0202, P0203, P0205, P0208 will set along with DTC P1262.
This FICM is for the 01-04 LB7 Duramax models (8th digit of VIN=1). If you have the 04-05 LLY model (8th digit of VIN=2), then click here.
