Perform a complete diagnostic scan of the vehicle's onboard computer systems to identify and retrieve diagnostic trouble codes (DTCs) from all modules including PCM, ABS, airbag, and body control modules.

Warnings

Tools required

Preparation

1. Park vehicle on level ground and set parking brake
2. Turn off all accessories including radio, HVAC, and lights
3. Ensure ignition is in OFF position
4. Locate OBD-II diagnostic port under driver's side dashboard, above brake pedal area
5. Verify scan tool is updated with latest software version for 2011-2014 Ford F-150 coverage

Procedure

1. 1

   Connect Diagnostic Scanner
   Plug the OBD-II scanner connector firmly into the diagnostic port located under the driver's side dashboard. Ensure the connection is secure and the scanner powers on. If using a Bluetooth or Wi-Fi scanner, verify connection to your mobile device or laptop.
2. 2

   Initialize Scanner Communication
   Turn ignition to ON position (engine OFF) without starting the vehicle. Wait for the scanner to establish communication with the vehicle's modules. Select 2011-2014 Ford F-150 with 5.0L V8 engine when prompted by the scanner menu.
3. 3

   Scan Powertrain Control Module (PCM)
   Navigate to the Powertrain or Engine Control Module section. Select 'Read Codes' or 'Retrieve DTCs'. Document all present codes (P-codes), pending codes, and freeze frame data. Note the code description and number of ignition cycles since code was set. Record live data streams for engine RPM, coolant temperature, fuel trims, and oxygen sensor readings if fault codes are present.
   ℹ️Freeze frame data captures operating conditions when the fault occurred and is critical for diagnosis
4. 4

   Scan Anti-Lock Brake System (ABS) Module
   Navigate to the ABS or Brake system module. Retrieve all ABS-related codes (C-codes). Document wheel speed sensor data, brake pressure readings, and any stored faults. Note if 4WD system codes appear here as some traction control functions are ABS-integrated.
5. 5

   Scan Airbag/Restraint Control Module (RCM)
   Access the Airbag or Supplemental Restraint System (SRS) module. Retrieve all airbag codes (B-codes related to restraints). Document all stored faults including seat belt pretensioners, airbag sensors, and crash sensor data. Verify airbag readiness status.
   ⚠Airbag system faults require immediate attention as they may prevent airbag deployment in a crash
6. 6

   Scan Body Control Module (BCM)
   Navigate to Body Control or Central Configuration module. Retrieve all body-related codes (B-codes and U-codes). Document faults related to lighting, door locks, power windows, instrument cluster, and other body electrical systems. Check for network communication faults (U-codes) between modules.
7. 7

   Scan 4WD and Transfer Case Module
   Access the 4WD or Transfer Case Control module. Retrieve codes related to four-wheel drive engagement, transfer case clutch operation, and shift motor function. Document any shift fork position errors or 4WD mode engagement failures specific to the electronic shift-on-the-fly system.
8. 8

   Scan Transmission Control Module (TCM)
   Navigate to the Transmission Control Module. Retrieve all transmission-related codes. Document shift solenoid faults, pressure control issues, torque converter clutch problems, and transmission temperature sensor readings. Review adaptive shift strategy values if scanner supports this function.
9. 9

   Check Additional Modules
   Scan any remaining available modules including HVAC control, instrument cluster, radio/SYNC system, and parking assist modules. Ford F-150s of this generation may have 20+ addressable modules depending on equipment level. Document all codes from each accessible module.
10. 10

    Review Network Communication
    Check for U-codes (network communication codes) that indicate modules are not communicating properly on the CAN bus network. Verify all expected modules are responding. Note any 'module not responding' or 'lost communication' faults as these indicate wiring or module power issues.
11. 11

    Document Complete Results
    Compile a comprehensive list of all DTCs found across all modules. Include code number, description, status (current/pending/history), freeze frame data, and which module reported the code. Note vehicle mileage and current date. Save or print scanner report if available. Take photos of scanner screen showing codes if necessary for records.
12. 12

    Disconnect Scanner
    Turn ignition to OFF position. Unplug the diagnostic scanner from the OBD-II port. Ensure the port cover is reinstalled if equipped. Store all documented codes and diagnostic data for repair planning.

Reassembly

1. No reassembly required for diagnostic scan procedure

Verification

• Confirm all diagnostic trouble codes have been properly documented with complete descriptions
• Verify freeze frame data has been recorded for any current or pending faults
• Ensure all vehicle modules have been scanned and communication has been verified
• Review that scanner has been disconnected and OBD-II port is accessible for future use
• Create a diagnostic plan based on retrieved codes prioritizing safety-critical systems (airbags, brakes, engine) first
