DTC IS ACTIVE
1. Ignition on, engine not running.
2. With the scan tool, erase DTCs in the Powertrain Control Module (PCM).
3. With the scan tool, actuate the Crankcase Vent Heater.
4. Monitor the scan tool for at least two minutes.
5. 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 Crankcase Vent Heater harness connector.
3. Disconnect the PCM C1 harness connector.
4. Remove the ASD Relay.
5. Connect a jumper between cavity 30 and cavity 87 of the ASD Relay connector.
6. Turn the ignition on.
7. Measure the voltage on the (N116) Crankcase Vent Heater Control circuit at the Crankcase Vent Heater harness connector.
  Is there any voltage present?
  
  Yes
  - Repair the (N116) Crankcase Vent Heater Control circuit for a short to voltage.
  - Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
  No
  - Go To 3

1. Turn the ignition off.
2. Remove the jumper and install the ASD relay.
3. Measure the resistance between the (N116) Crankcase Vent Heater Control circuit and the (F343) Fused ASD Relay Output circuit at the Crankcase Vent Heater harness connector.
  Is the resistance above 10k Ohms?
  
  Yes
  - Go To
  No
  - Repair the (N116) Crankcase Vent Heater Control circuit for a short to the (F343) Fused ASD Relay Output circuit.
  - Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
CRANKCASE VENT HEATER
1. Turn the ignition off.
2. Reconnect the PCM C1 harness connector.
3. Turn the ignition on.
4. Start the engine and allow it to idle.
5. Monitor the scan tool for at least two minutes.
6. With the scan tool, select View DTCs.
  NOTE:
  The P053A-Crankcase Vent Heater Control Circuit Open DTC should be active or pending with the jumper in place.
  
  Did the DTC display as described above?
  
  Yes
  - Replace the Crankcase Vent Heater.
  - Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
  No
  - Go To 5
POWERTRAIN CONTROL MODULE (PCM)
1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Crankcase Vent Heater and the Powertrain Control Module (PCM).
  - Look for any chafed, pierced, pinched, or partially broken wires.
  - Look for broken, bent, pushed out or corroded terminals.
  - 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 and program the Powertrain Control Module in accordance the service information. Refer to MODULE, POWERTRAIN CONTROL, REMOVAL .
  - Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
