Diagnose and repair any other DTCs set in the PCM before proceeding with this test.
1. Turn the ignition on.
2. With the scan tool, Clear DTCs in the Powertrain Control Module (PCM).
3. Start the engine and allow it to reach operating temperature.
  WARNING:
  When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts or fan. Do not wear loose clothing. Failure to follow these instructions may result in possible serious or fatal injury.
4. With the scan tool, select View DTCs.

1. Turn the ignition off.
2. Disconnect the C1 PCM harness connector.
  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 PCM Pinout Box (special tool #8815A, Kit, NGC, 38 Position) to perform diagnosis.
3. With a 12-volt test light connected to ground and with special tool (special tool #8815A, Kit, NGC, 38 Position) installed, probe the (F202), (F1), and (T751) Fused Ignition Switch circuits.
4. Perform the above check with the Ignition key in the off lock position, Ignition on, engine not running position, and during cranking.
5. Wiggle the related wire harness while probing the special tool with the test light to try to interrupt the circuit.
  Does the test light illuminate brightly?
  
  Yes
  - Go To 3.
  No
  - Repair the open or excessive resistance in the (F202), (F1), and (T751) Fused Ignition Switch (Off, Run, Start) circuits. Inspect the related fuse, if the fuse is open check the circuits for a short to ground.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
POWERTRAIN CONTROL MODULE (PCM)
1. Verify that the PCM is operating at the latest software version available.
2. Refer to any Technical 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 and program the Powertrain Control Module (PCM) in accordance with the Service Information.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
