Circuit/System Description

The position of the swirl flaps is controlled by the engine control module (ECM). The ECM controls the intake manifold runner control solenoid valve to create a swirl in the combustion chamber to get a homogeneous diesel air mixture. The ECM will vary the intake manifold runner control solenoid valve referring to the barometric pressure and the mass air flow. The ECM uses a pulse width modulation on the control circuit to control the intake manifold runner control solenoid valve.

Conditions for Running the DTC

The engine is running.

Conditions for Setting the DTC

The ECM detects a wrong frequency from the intake manifold runner control solenoid valve.

Action Taken When the DTC Sets

DTC P2015 is a Type A DTC.

Conditions for Clearing the DTC

DTC P2015 is a Type A DTC.

Circuit/System Verification

  1. Ignition ON, command the Q21 Intake Manifold Runner Control Solenoid Valve ON and OFF with a scan tool. Observe the Intake Manifold Runner Control Valve Feedback Signal parameter.
  2. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.

Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the Q21 Intake Manifold Runner Control Solenoid Valve.
  2. Test for less than 5 Ω between the low reference circuit terminal 2 and ground.

    3. If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the K20 Engine Control Module.

  3. Disconnect the X1 harness connector at the K20 Engine Control Module.
  4. Ignition ON, test for less than 0.3 V between the signal circuit at the Q21 Intake Manifold Runner Control Solenoid Valve terminal 5 and ground.

    5. If greater than the specified range, test the signal circuit for a short to Voltage. If the circuit tests normal, replace the K20 Engine Control Module.

  5. Ignition OFF, test for greater than 500 kΩ between the signal circuit terminal 5 and ground.

    6. If less than the specified range, test the signal circuit for a short to ground. If the circuit tests normal, replace the K20 Engine Control Module.

  6. Test for less than 5 Ω between the signal circuit at the Q21 Intake Manifold Runner Control Solenoid Valve terminal 5 and the signal circuit at the K20 Engine Control Module terminal listed below:
    7. •  LCD/LBX/LBS Terminal 43 X1
    •  LBY Terminal 91 X1

    If greater than the specified range, test the signal circuit for an open circuit. If the circuit tests normal, replace the K20 Engine Control Module.

  7. Connect the X1 harness connector at the K20 Engine Control Module.
  8. Ignition ON, connect a test lamp between the ignition circuit terminal 6 and ground.

    9. If the test lamp is OFF, test the ignition circuit for a short to ground or an open/high resistance.

  9. Connect a test lamp between the control circuit terminal 1 and the ignition circuit terminal 6.
  10. Command the Intake Manifold Runner 95% to 5% and back with a scan tool. The test lamp intensity should increase or degrease as commanded with the scan tool.

    11. If the test lamp is always full bright, test the control circuit for a short to ground. If the circuit tests normal, replace the K20 Engine Control Module.

    If the test lamp is always OFF or dimmed, test the control circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the K20 Engine Control Module.

    If the test lamp intensity does not vary, replace the K20 Engine Control Module.

  11. If all circuits test normal, replace the Q21 Intake Manifold Runner Control Solenoid Valve.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
