Diagnostic Test

  1. CHECK FOR AN ACTIVE DTC 
    1. Turn the ignition on.
    2. With the scan tool, read DTCs and record on the repair order.

      Is the DTC active or pending?

      Yes 

      • Go To  2

      No 

  2. INSPECT THE ACTIVE EXHAUST VALVE ASSEMBLY FOR SIGNS OF PHYSICAL DAMAGE 
    1. Inspect the Active Exhaust Valve 1 Assembly and connector for damage due to road debris.

      Is the Active Exhaust Valve 1 Assembly or connector damaged or disconnected?

      Yes 

      No 

      • Go To  3
  3. CHECK THE (A947) FUSED B+ CIRCUIT 
    1. Turn the ignition off.
    2. Disconnect the Active Exhaust Valve 1 harness connector.
    3. Measure the voltage on the (A947) Fused B+ circuit at the Active Exhaust Valve 1 harness connector.

    4. Is the voltage equal to battery voltage?

      Yes 

      • Go To  4

      No 

      • Repair the (A947) Fused B+ circuit for an open or short to ground.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  4. CHECK THE (Z922) GROUND CIRCUIT FOR AN OPEN/HIGH RESISTANCE 
    1. Check for continuity between ground and the (Z922) Ground circuit at the Active Exhaust Valve 1 harness connector.

      Is there continuity between ground and the (Z922) Ground circuit?

      Yes 

      • Go To  5

      No 

      • Repair the (Z922) Ground circuit for an open or high resistance.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  5. CHECK THE (D511) LIN BUS CIRCUIT FOR A SHORT TO GROUND 
    1. Disconnect the PCM C1 harness connector.
    2. Check for continuity between ground and the (D511) LIN BUS circuit at the Active Exhaust Valve 1 harness connector.

      Is there continuity between ground and the (D511) LIN BUS circuit?

      Yes 

      • Repair the (D511) LIN BUS circuit for a short to ground.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .

      No 

      • Go To  6
  6. CHECK THE (D511) LIN BUS CIRCUIT FOR AN OPEN/HIGH RESISTANCE 
    CAUTION:

    Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal to pin connection. Install the GPEC Diagnostic Adaptor to perform the diagnosis.

    1. Connect the (special tool #10436, Adapter, GPEC Diagnostic).
    2. Measure the resistance of the (D511) LIN BUS circuit between the Active Exhaust Valve 1 harness connector and the GPEC Adaptor.

      Is the resistance below 3.0 Ohms?

      Yes 

      • Go To  7

      No 

      • Repair the (D511) LIN BUS circuit for an open or high resistance.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  7. ACTIVE EXHAUST VALVE ASSEMBLY (AEV) 
    1. Replace the Active Exhaust Valve Assembly in accordance with the Service Information.
    2. Reconnect the PCM harness connector.
    3. Turn the ignition on.
    4. With the scan tool, erase DTCs.
    5. With the scan tool, actuate the AEV Assembly.
    6. With the scan tool, read DTCs.

      Did the DTC return?

      Yes 

      • Go To  8

      No 

  8. CHECK RELATED PCM AND COMPONENT CONNECTIONS 
    1. Perform any Service Bulletins that apply.
    2. Disconnect all PCM harness connectors.
    3. Disconnect all related in-line harness connections (if equipped).
    4. Disconnect the related component harness connectors.
    5. Inspect harness connectors, component connectors, and all male and female terminals for the following conditions:
      • Proper connector installation.
      • Damaged connector locks.
      • Corrosion.
      • Other signs of water intrusion.
      • Weather seal damage (if equipped).
      • Bent terminals.
      • Overheating due to a poor connection (terminal may be discolored due to excessive current draw).
      • Terminals that have been pushed back into the connector cavity.
      • Check for spread terminals and verify proper terminal tension.

      Repair any conditions that are found.

    6. Reconnect all PCM harness connectors. Be certain that all harness connectors are fully seated and the connector locks are fully engaged.
    7. Reconnect all in-line harness connectors (if equipped). Be certain that all connectors are fully seated and the connector locks are fully engaged.
    8. Reconnect all related component harness connectors. Be certain that all connectors are fully seated and the connector locks are fully engaged.
    9. With the scan tool, erase DTCs.
    10. Test drive or operate the vehicle in accordance with the when monitored and set conditions.
    11. With the scan tool, read DTCs.

      Did the DTC return?

      Yes 

      No 

      • The wiring or poor connection problem has been repaired.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
