The FICM (Fuel Injection Control Module) controls the electrical impulses that control the fuel injectors. The fuel injector ignition voltage circuit is Pulse Width Modulated (PWM) , between 20 volts at idle to approximately 93 volts in order to compensate for increased engine load and RPM. The fuel injector control module energizes each fuel injector by grounding the command circuit between the fuel injector control module and the fuel injector. The fuel injector control module monitors the status of the ignition voltage circuits and the fuel injector command circuits. When a fuel injector circuit 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 condition is detected on a fuel injector circuit for cylinders 1, 4, 6, or 7, DTCs P0201, P0204, P0206, P0207 will set, along with DTC P1261. If a circuit condition is detected on a fuel injector circuit for cylinders 2, 3, 5, or 8, DTCs P0202, P0203, P0205, P0208 will set, along with DTC P1262.
