Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Disconnect the 12V battery to reset the system (if necessary).

2. Inspect Wheel Speed Sensors

Remove the wheel covers if applicable.
Carefully remove the wheels using a socket set.
Inspect the wheel speed sensors for any signs of damage or debris.
Clean the sensors with electrical contact cleaner if dirt is present.

3. Check Tire Condition

Measure tire pressure with a tire pressure gauge and inflate to the manufacturer’s specifications.
Inspect tire tread depth using a tread depth gauge; replace tires if tread is below the recommended depth.

4. Software Update

Connect the vehicle to Wi-Fi and check for available software updates via the Tesla app or vehicle settings.
Follow on-screen instructions to complete any updates.

5. Reconnect Battery and Test

Reconnect the 12V battery.
Turn on the vehicle and check if the traction control light remains illuminated.
Test drive the vehicle to assess if the traction control system operates correctly.
