Inspection and Verification

WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. 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) where not originally equipped, may cause the TPMS system to malfunction and is therefore not recommended.
  1. Verify the customer concern by inspecting the vehicle and observing the message center (if equipped) 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 will adversely affect TPMS operation.
    NOTE: Swapping wheels between vehicles with the same tire pressure monitoring system will cause a TPMS fault to be set if the sensors are not trained. REFER to TIRE PRESSURE MONITORING SYSTEM (TPMS) SENSOR TRAINING  in this article.
    NOTE: Non-original equipment manufacturer (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
    • TPMS sensor damaged or missing
    • Spare tire installed as a road wheel
    • Incorrect TPMS sensor installed
    • TPMS sensor installed incorrectly
    • Non-OEM wheels installed (aftermarket rims)
    • Non-OEM equipped run-flat tires installed
    • Other non-OEM modifications (roll cages, service barriers, part racks, ladder racks)
    • Circuitry
    • Electrical connectors
    • SJB missing or damaged
    • 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. If the cause is not visually evident, connect the scan tool to the data link connector (DLC) and select the vehicle to be tested from the scan tool menu. If the scan tool does not communicate with the vehicle:
    • check that the program card is correctly installed.
    • check the connections to the vehicle.
    • check the ignition switch position.
    • verify that the battery voltage is between 10 and 16 volts. Refer to CHARGING SYSTEM - GENERAL INFORMATION .
  5. If the scan tool still does not communicate with the vehicle, refer to the scan tool manual.
  6. Carry out the DATA LINK DIAGNOSTIC TEST. If the scan tool responds with:
    • CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to MODULE COMMUNICATIONS NETWORK .
    • SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out self-test diagnostics for the SJB module. Refer to MULTIFUNCTION ELECTRONIC MODULES .
  7. If the DTCs retrieved are related to the concern, refer to TIRE PRESSURE MONITOR SYSTEM (TPMS) DIAGNOSTIC TROUBLE CODE (DTC) INDEX  to continue diagnostics.
  8. If no DTCs related to the concern are retrieved, GO to SYMPTOM CHART  to continue diagnostics.
