Engine Brake Actuator Circuit #2 – Voltage Above Normal or Shorted to High Source
|Fault Code: 2367
Engine Brake Actuator Circuit #2 – Voltage Above Normal or Shorted to High Source. Open circuit or high voltage detected at the engine brake solenoid number 2 signal circuit.
Engine brake on cylinders 4, 5, and 6 can not be activated.
Engine Brake Circuit
The ECM controls engine brakes on cylinders 4, 5, and 6 by sending a signal on the engine brake solenoid number 2 signal circuit. A 2-pin Weather Pack connector is located near the number 3 injector pass-through connector at the back of the engine. There is a jumper harness from this connector to the engine brake pass-through connectors on the rocker lever housing.
The engine brake solenoids are located under the valve cover. The engine brake solenoids are controlled through the engine harness from the ECM.
Possible causes of this fault code include:
- Open circuit in the engine harness, brake harness, or engine brake solenoids
- Short to voltage source in the engine harness
- Failed ECM.
