Inspection and Verification

WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
    NOTE: The tire pressure sensors are not designed to be used with aftermarket wheels.
    NOTE: The use of run-flat tires (tires with steel body cord plies in the tire sidewall) or rigid sidewall tires (19.5" steel carcass heavy-duty tires) where not originally equipped, may cause the TPMS to malfunction and are not recommended.
  1. Verify the customer concern by inspecting the vehicle and observing the message center and the TPMS indicator.
    2. NOTE: The valve-mounted TPMS sensors and the strap-mounted TPMS sensors are not compatible. Swapping wheels from one vehicle to another with the different systems sets a TPMS fault.
    NOTE: Swapping wheels between vehicles with the same TPMS causes a TPMS fault to be set if the sensors are not trained. Refer to Tire Pressure Monitoring System (TPMS) Sensor Training .
    NOTE: Non-OEM modifications made to the vehicle may result in false TPMS warnings.
  2. Inspect to determine if one of the following mechanical or electrical concerns apply:
    VISUAL INSPECTION CHART

    Mechanical Electrical
    • Low tire pressure
    • Tire Pressure Monitoring System (TPMS) sensor damaged or missing
    • Spare tire installed as a road wheel
    • Incorrect TPMS sensor installed
    • TPMS sensor installed incorrectly
    • Sensors not trained after a tire rotation on vehicles with different front and rear tire pressures
    • Non-OEM wheels installed (aftermarket rims)
    • Non-OEM equipped run-flat tires or rigid sidewall tires (19.5" steel carcass heavy-duty tires) installed
    • Other non-OEM modifications (roll cages, service barriers, part racks, ladder racks)
    • Body Control Module (BCM) fuse 24 (15A)
    • Wiring, terminals or connectors
    • Aftermarket electronic accessories
  3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
    4. NOTE: Make sure to use the latest scan tool software release.
  4. If the cause is not visually evident, connect the scan tool to the Data Link Connector (DLC).
    5. NOTE: The Vehicle Communication Module (VCM) LED prove out confirms power and ground from the DLC are provided to the VCM.
  5. If the scan tool does not communicate with the VCM:
    • check the VCM connection to the vehicle.
    • check the scan tool connection to the VCM.
    • refer to MODULE COMMUNICATIONS NETWORK , No Power To The Scan Tool, to diagnose no power to the scan tool.
  6. If the scan tool does not communicate with the vehicle:
    • verify the ignition key is in the ON position.
    • verify the scan tool operation with a known good vehicle.
    • refer to MODULE COMMUNICATIONS NETWORK to diagnose no response from the PCM.
  7. Carry out the network test.
    • If the scan tool responds with no communication for one or more modules, refer to MODULE COMMUNICATIONS NETWORK .
    • If the network test passes, retrieve and record Continuous Memory Diagnostic Trouble Codes (CMDTCs).
  8. Clear the CMDTCs and carry out the self-test diagnostics for the BCM and the TPM module.
  9. If the DTCs retrieved are related to the concern, go to the Body Control Module (BCM) DTC Chart  or the TIRE PRESSURE MONITOR (TPM) MODULE DTC CHART . For all other DTCs, refer to the Diagnostic Trouble Code (DTC) Chart in MULTIFUNCTION ELECTRONIC MODULES .
  10. If no DTCs related to the concern are retrieved, GO to Symptom Chart .
