Cummins ISB CM850 (2003-06) Fault Code: 2366 PID: SID 28 SPN: 1072 FMI: 3 Engine Brake Actuator Circuit #1 – Voltage Above Normal or Shorted to High Source. Open circuit or high voltage detected at the engine brake solenoid number 1 signal circuit.
Possible causes:
1)Open circuit in the engine harness, brake harness, or engine brake solenoids
2)Short to voltage source in the engine harness
3)Failed ECM.
Possible repairs:
1)Replace the engine brake solenoid.
2)Replace the ECM.
3)Repair or replace the engine harness.
