DTC IS ACTIVE
1. Ignition on, engine not running.
2. With the scan tool, select View DTCs.
  Is the status Active for this DTC?
  
  Yes
  - Go To 2
  No
  - Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT DTC .

1. Turn the ignition off.
2. Disconnect the Boost Pressure Actuator harness connector.
3. Turn the ignition on.
4. Using a 12-volt test light connected to ground, check the (F343) Fused ASD Relay Output circuit in the Boost Pressure Actuator harness connector.
  NOTE:
  The test light should be illuminated and bright. Compare the brightness to that of a direct connection to the battery.
  
  Is the test light illuminated and bright?
  
  Yes
  - Go To 3
  No
  - Repair the (F343) Fused ASD Relay Output circuit for an open or high resistance. Inspect the related fuse, an open fuse may indicate a short to ground in the circuit.
  - Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .

1. Turn the ignition off.
2. Disconnect the PCM C1 harness connector.
3. Measure the resistance of the (K137) Boost Pressure Actuator Control circuit between the Boost Pressure Actuator harness connector and the PCM C1 harness connector.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Go To 4
  No
  - Repair the (K137) Boost Pressure Actuator Control circuit for an open or high resistance.
  - Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
BOOST PRESSURE ACTUATOR
1. Reconnect the Boost Pressure Actuator harness connector.
2. Reconnect the PCM C1 harness connector.
3. Turn the ignition on.
4. With the scan tool, erase DTCs.
5. Turn the ignition off.
6. Disconnect the Boost Pressure Actuator harness connector.
7. Connect a jumper between ground and the (K137) Boost Pressure Actuator Control circuit at the Boost Pressure Actuator harness connector.
8. Turn the ignition on.
9. With the scan tool, view DTCs.
  NOTE:
  The scan tool should display a P0047-Turbocharger Boost Control Circuit Low DTC with the jumper in place.
  
  Did the scan tool display the DTC as described above?
  
  Yes
  - Replace the Turbocharger assembly in accordance with the service information. Refer to TURBOCHARGER, REMOVAL .
  - Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
  No
  - Go To 5
POWERTRAIN CONTROL MODULE
1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Boost Pressure Actuator and the Powertrain Control Module (PCM).
2. Look for any chafed, pierced, pinched, or partially broken wires.
3. Look for broken, bent, pushed out or corroded terminals.
4. Perform any Technical Service Bulletins that may apply.
  Were any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
  No
  - Replace the Powertrain Control Module in accordance with the service information. Refer to MODULE, POWERTRAIN CONTROL, REMOVAL .
  - Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
