Brought in for an intermittent, rough running engine and white smoke out the tailpipe, the truck was interfaced with a scan tool to check for DTCs. This will cause injector damage from solenoid coil overheating. 6) You can use an LED in series with a 330 ohm (or 270 ohm) resistor and probe the input and output of various circuits, like the injector driver, to make sure that these are working. Injector Driver Circuit. I have a 2004 444E that has a trouble code that says: 525,injector driver circuit fault " M ". P0204 (M) Injector #4 Control Circuit Injector #4 or INJ 4 injector bank output driver stage does not respond properly to the control signal. Turn ignition on. Code #27: Quad-Driver Module #2 Circuit. The ECM energizes each fuel injector by grounding the control circuit and supplying each fuel injector with up to 250 V and 20 amps on the voltage supply circuit to activate the piezo type fuel injectors. 525,injector driver circuit fault " M ". Conversely, when a fuel injector is commanded "on" by the PCM, it expects to see the voltage pulled low on the driver circuit If it doesn't see this expected condition. What does that mean? P0203 means that the PCM detected a fault in the injector or the wiring to the injector. They include the engine control module, body, chassis, etc. For example, when a fuel injector is commanded "off" by the PCM, it expects to see a high voltage on the driver ground circuit. When the ECM has detached a fault in the injector for cylinder 6 or a fault in the wiring for the injector, this code is triggered. P1219 = Injector solenoid valve cylinder 2 - Voltage too low or short circuit to ground on ECU (D420) pin (A9) P1220 = Injector solenoid valve cylinder 2 - Voltage too high or short circuit to supply on ECU (D420) pin (A9) P1221 = Injector solenoid valve cylinder 4 - Current too low or open circuit on ECU (D420) pin (A11) and/or pin (A12).

The primary circuit leads from the ignition switch or resistor to the ignition coil. Is the repair complete? Repair the open ignition feed circuit between the fuel injector harness connector and the fuel injector connector. There are 2 (sometimes 3) more connectors in the harness down by the starter. Replacing the "CELECT" series in 1995, Cummins moved the M11 & N14 to the "CELECT PLUS" platform in 1995 and used it until 1998. RTK is correct about the 14 volt as an indicator. Check engine light on with this code: P2149-FUEL INJECTOR GROUP 2 SUPPLY VOLTAGE CIRCUIT I have an Edge w/ Attitude monitor. Cylinder 12. I had a diagnostic fault code check and these are the fault codes on my peogeut urban 2 tronic 1. With this information it is easier to trouble shoot a DTC. i did have the dealership change an injector harness on the passenger side of the truck because it was leaking but that was a. Some ECUs have a driver circuit that can go to ground when powered off; cars like this will be wired so power to the ECU and the injectors is cut at the same time. 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. Part of a project I'm working on requires the development of a driver circuit for a direct-injection fuel injector. Engines that need high pressure fuel injection rely on injector driver modules to control the fuel injection system. Cylinder 2 Injector Circuit Malfunction. Using a scope, you can view a waveform pattern of the injector circuit operation. Possible causes include: Bad injector on cylinder 6; Open or short in the wiring to injector for cylinder 6; Bad ECM (rare) P0300 - Random Misfire. 6L engine was one of the first systems to employ such an ECM.
