Diagnostic Test

CHECK FOR AN ACTIVE DTC
NOTE:
If the PCM detects and stores a DTC, the PCM also stores the engine/vehicle operating conditions under which the DTC was set. Some of these conditions are displayed on the scan tool at the same time the DTC is displayed. Before erasing stored DTCs, record these conditions. Attempting to duplicate these conditions may assist when checking for an active DTC.

NOTE:
If there are other DTCs set with this DTC, repair other DTCs before continuing with this diagnostic procedure.

NOTE:
This code can be caused by an intermittent problem in the wiring and connectors to the Powertrain Control Module. Inspect the Powertrain Control Module harness connector and associated wiring for signs of poor terminal contact.
1. Turn the ignition on.
2. With the scan tool, erase DTCs in the Powertrain Control Module.
3. Monitor the scan tool for at least two minutes.
4. Cycle the ignition key off and on several times, leaving the ignition on for at least 10 seconds at a time.
5. Start the engine.
6. Perform several engine run cycles, turning the ignition off for at least 20 seconds between each engine run cycle leaving the ignition on.
7. With the scan tool, read DTCs and record on the repair order.
  Is the DTC active?
  
  Yes
  - Go To 2
  No
  - Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT CONDITION .
POWERTRAIN CONTROL MODULE
1. Using appropriate SYSTEM WIRING DIAGRAMS/schematic as a guide, inspect the wiring and connectors for the Powertrain Control Module.
2. Look for any chafed, pierced, pinched, or partially broken wires.
3. Look for broken, bent, pushed out or corroded terminals.
4. Monitor the scan tool data relative to this circuit and wiggle test the wiring and connectors.
5. Look for the data to change or for the DTC to reset during the wiggle test.
6. Perform any Service Bulletins that may apply.
  Were any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Replace the Powertrain Control Module in accordance with the Service Information. Refer to MODULE, POWERTRAIN CONTROL (PCM), REMOVAL AND INSTALLATION .
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
