For a few weeks now, a software update has been causing Tesla has been causing trouble among drivers. Error messages in the tire pressure monitoring system (TPMS) particularly unsettled owners of Tesla Model 3 and Tesla Model Y. But now the all-clear has finally been given: With the new update 2024.44.x has Tesla fixed the problem and the sensors are working properly again.

What was the problem?
After installing the update 2024.38.4+ many Tesla-drivers experienced error messages indicating problems with the BLE tire pressure sensors indicated. The error code "VCSEC_a222" was frequently reported. This affected both the original Tesla-sensors as well as aftermarket models.

Background to the problem:
Tesla had the reporting interval of the sensors increased. The tire pressure sensors now had to transmit the current pressure more frequently. If this was not fulfilled on time, the software triggered an error message, even though the sensors were working perfectly from a technical point of view.

The solution: Update 2024.44.x
With the published update 2024.44.x has Tesla fixed the problem on the software side. User reports from the TFF forum confirm that the tire pressure sensors are now working normally again. It is therefore no longer necessary to remove or replace the sensors.

What this alert means:

Autosteer is temporarily unavailable. This could be a temporary condition caused by an external factor, such as:

  • Missing or faded lane markers.
  • Narrow or winding roads.
  • Poor visibility due to rain, snow, fog, or other weather.
  • Extremely hot or cold temperatures.
  • Bright light due to other vehicle headlights, direct sunlight, or other light sources.

This alert will also be present if you exceeded the maximum speed limit for Autosteer with Autosteer active. In this case, Autosteer will not be available for the rest of your current drive.

What to do:

Continue to your destination. If Autosteer is not available by the time you reach your destination, and remains unavailable during your next planned drive, check for the following:

  • Damage or obstruction caused by mud, ice, snow, or other environmental factors
  • Obstruction caused by an object mounted on the vehicle, like a bike rack
  • Obstructions caused by adding paint or adhesive products like wraps, stickers, or rubber coatings to your vehicle
  • A damaged or misaligned bumper

If there are no obvious obstructions, or if you find damage to the vehicle, schedule service at your convenience. Your vehicle is OK to drive in the meantime.

For more information, see Autopilot Features.

What this alert means:

One or more of the vehicle cameras has limited visibility, or no visibility at all, due to external conditions. When the cameras on your vehicle cannot provide accurate visual information, some or all Autopilot features may be temporarily unavailable.

Cameras may have limited or no visibility due to:

  • Dirt or debris on the camera surface.
  • Environmental conditions like rain, fog, snow, or dew.
  • Bright sunlight or glare from another light source.
  • Low or limited light conditions, including unlit or poorly lit roadways at night.
  • Condensation (water droplets or mist) on the camera surface.
  • Monotonous environmental features, including tunnel walls or highway dividers.

What to do:

Continue to your destination. Your vehicle is OK to drive. This is often a temporary issue that will be resolved when condensation evaporates, or when a particular environmental condition or feature is no longer present.

If the alert does not clear by the time you reach your destination, check camera surfaces for condensation, dirt, or other debris. For camera locations, see Cameras.

Clean the cameras as necessary before your next planned drive. For recommended cleaning procedures, see Cleaning a Camera.

If you continue to see this alert after cleaning the cameras, check the inside surfaces of the door pillar camera enclosures for condensation. Although condensation inside the camera enclosures cannot be wiped clean, you can usually clear it faster by following these steps:

  1. Precondition the cabin by turning Climate ON, setting temperature to High, and making sure A/C is ON.
  2. Turn on the front windshield defroster.
  3. Direct the air vents toward the door pillar cameras.

For more information on clearing condensation from camera enclosures, see Cleaning a Camera.

If the alert does not clear by the end of your next planned drive, despite cleaning the indicated camera(s) and following recommended steps to clear condensation, schedule service at your next convenient opportunity. Your vehicle is OK to drive in the meantime.

What this alert means:

Wall Connector hardware issue. Possible issues include:

  1. Contactor not working
  2. Self-test of internal ground fault monitoring circuit failed
  3. Thermal sensor disconnected
  4. Other hardware component issues

What to do:

An internal issue was detected by the Wall Connector.

  1. Try charging again by disconnecting the Wall Connector from the vehicle and reconnecting.
  2. If the issue persists, turn OFF the circuit breaker for the Wall Connector, wait 10 seconds, and turn the circuit breaker ON again. Then try reconnecting the Wall Connector to the vehicle.
