Tire Pressure Sensor Fault in Mercedes-Benz GLC

October 22, 2024 TirePressureFault Mercedes-Benz 0

The TPMS (Tire Pressure Monitoring System) in the GLC Series ensures tire safety and performance, but you may see a “Tire Pressure Sensor Fault” for various reasons:

  • Low Tire Pressure: Even slight variations in tire pressure, often due to temperature changes or slow leaks, can trigger the warning.
  • Faulty or Worn Sensors: Over time, the TPMS sensors may become damaged, especially if you drive in rough conditions or after a tire change.
  • Battery Depletion: The small batteries inside the TPMS sensors typically last 5-7 years. Once the battery runs low, the sensor will stop working correctly.
  • Improper Reset: If you’ve recently rotated or changed your tires, the system might not recalibrate automatically and will need a manual reset.
  • Software Issues: Occasionally, a software glitch may cause a false tire pressure sensor fault, requiring a software update or reset.

Steps to Fix the Tire Pressure Sensor Fault in Mercedes-Benz GLC

  1. Check Tire Pressure:
    • Use a tire pressure gauge to check if each tire is properly inflated. The recommended levels are usually listed on a sticker inside the driver’s door or in the owner’s manual.
    • Inflate or adjust the tire pressure as necessary.
  2. Reset the TPMS System:
    • Turn the ignition to the ON position without starting the engine.
    • Use the steering wheel buttons to access the “Service” menu on the dashboard.
    • Navigate to “Tire Pressure”, and select “Restart”.
    • Confirm the reset, and drive for a few minutes to allow the system to recalibrate.
  3. Inspect the TPMS Sensors:
    • If the warning persists, the sensor may be damaged or the battery may need replacement.
    • Visit a Mercedes-Benz service center to have the sensors tested and replaced if necessary.
  4. Perform a Software Update:
    • If the sensors are in good condition, the problem may be software-related. Check with your dealer to see if a software update is available.
  5. Seek Professional Help:
    • If resetting and updating don’t resolve the issue, a professional diagnostic test at a Mercedes-Benz service center can identify the root cause.

Preventing Future Tire Pressure Sensor Faults in GLC Series

  • Regularly check your tire pressure, especially during extreme temperature changes or before long trips.
  • Replace the TPMS sensors every 5-7 years or when changing tires to avoid battery issues.
  • Always reset the system after tire maintenance, like rotations or replacements.
