s654 F05 (P0204) - Injector 3 Circuit fault
Control Module: ECU
Context:
Hardware errors in the injectors and their respective Engine Control Unit (ECU) A-009 power stages are investigated
within the ECU A-009. The ECU A-009 diagnostic procedure uses pattern detection to identify specific errors. When
an expected combination of errors is detected, the associated fault occurs. This fault will result in the Diesel Particulate
Filter (DPF) regeneration control to stop, the Exhaust Gas Recirculation (EGR) valve Z-005 control to stop, an engine
torque reduction and an engine idle increase.
Possible failure modes:
1. Faulty cylinder 2 injector Y-001, internal failure.
2. Faulty cylinder 2 injector Y-001 wiring, open or shorted.
3. Faulty ECU A-009, software.
