Diagnostic Test

CHECK FOR ACTIVE DTC
1. Turn the ignition on.
2. With the scan tool, read the active DTCs.
  Does the scan tool display this DTC as active?
  
  Yes
  - Go to step 2
  No
  - If the DTC is stored, check for an intermittent condition. Using the wiring diagram/schematic as a guide, visually inspect the related wiring harness connectors. Look for broken, bent, pushed out, or corroded terminals.
  - Perform the BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure .

1. Turn the ignition off.
2. Disconnect the IPM C1 harness connector.
3. Disconnect the PCM C1 harness connector.
4. Turn the ignition on.
5. Measure the voltage of the (F1) Fused Ignition Switch Output (Off-Run-Start) circuit at the IPM C1 harness connector.
  Is the voltage above 10.0 volts?
  
  Yes
  - Repair the (F1) Fused Ignition Switch Output (Off-Run-Start) circuit for a short to voltage.
  - Perform the BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure .
  No
  - Go to step 3
POWERTRAIN CONTROL MODULE INTERNALLY SHORTED

1. Reconnect the Powertrain Control Module C1 harness connector.
2. Measure the voltage of the (F1) Fused Ignition Switch Output (Off-Run-Start) circuit at the IPM C1 harness connector.
  Is the voltage above 10.0 volts?
  
  Yes
  - Replace the Powertrain Control Module in accordance with the Service Information.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Go to step 4
CHECK FCM AND IPM FOR A SHORT TO VOLTAGE
1. Disconnect the Front Control Module from the IPM.
2. Measure the voltage of the (F1) Fused Ignition Switch Output (Off-Run-Start) circuit at the male terminal of the IPM C1 connector.
  Is the voltage above 10.0 volts?
  
  Yes
  - Replace the IPM in accordance with the Service Information.
  - Perform the BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure .
  No
  - Replace the Front Control Module (FCM) in accordance with the Service Information.
  - Perform the BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure .
