WARNING: This page is about a different car, the 2005 Ford Pickup, 2005 Ford F550 Super Duty, 2005 Ford F450 Super Duty, and 2005 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

F1 RETRIEVE THE RECORDED POWERTRAIN CONTROL MODULE (PCM) AND INSTRUMENT CLUSTER DTCs FROM BOTH THE CONTINUOUS AND ON-DEMAND SELF-TESTS
- Check for recorded PCM and instrument cluster DTCs from both the continuous and on-demand self-tests.
- Are any instrument cluster DTCs recorded?
- Yes : REFER to the INSTRUMENT CLUSTER DIAGNOSTIC TROUBLE CODE (DTC) INDEX to continue diagnosis.
  If any PCM DTCs are present, See INTRODUCTION - GASOLINE article or INTRODUCTION -- 6.0L DIESEL article to continue diagnosis of the DTCs.
- No : GO to F2.
F2 CARRY OUT THE INSTRUMENT CLUSTER TRANSMISSION TEMPERATURE GAUGE ACTIVE COMMAND USING THE DIAGNOSTIC TOOL
- Key in ON position.
- Enter the following diagnostic mode on the diagnostic tool: Instrument Cluster Active Command.
- Select the instrument cluster transmission temperature gauge active command. Trigger, monitor, and scroll the transmission temperature gauge at: 0%, 50%, and 100%.
- Does the transmission temperature gauge display: low (L) with 0%, half with 50%, and high (H) with 100%?
- Yes : GO to F4.
- No : GO to F3.
F3 CHECK FOR CORRECT INSTRUMENT CLUSTER OPERATION
- Disconnect all the instrument cluster connectors.
- Check for:
  - corrosion
  - pushed-out pins
- Connect all the instrument cluster connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
- Yes : INSTALL a new instrument cluster. REFER to INSTRUMENT CLUSTER . TEST the system for normal operation.
- No : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
F4 CHECK FOR CORRECT POWERTRAIN CONTROL MODULE (PCM) OPERATION
- Disconnect all the PCM connectors.
- Check for:
  - corrosion
  - pushed-out pins
- Connect all the PCM connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
- Yes : INSTALL a new PCM. REFER to ELECTRONIC ENGINE CONTROLS - GASOLINE ENGINES (gasoline engines), or ELECTRONIC ENGINE CONTROLS - DIESEL ENGINE (diesel engines). TEST the system for normal operation.
- No : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
