Solution

1. Preparation

• Gather tools: laptop with Tesla diagnostic software, multimeter, basic hand tools.
• Ensure the vehicle is parked on a flat, safe surface and powered off.

2. Inspect Wheel Speed Sensors

• Sub-step 1: Remove the wheel covers and check each wheel speed sensor for physical damage or dirt.
• Sub-step 2: Clean the sensors using a soft cloth if dirt is present.
• Sub-step 3: Use a multimeter to check the sensor's resistance; it should typically be within manufacturer specifications.

3. Examine ABS Module

• Sub-step 1: Locate the ABS module (usually found near the brake master cylinder).
• Sub-step 2: Check all wiring harness connections for loose wires or corrosion.
• Sub-step 3: If necessary, use the Tesla diagnostic tool to run a self-test on the ABS module.

4. Check Traction Control Switch

• Sub-step 1: Locate the traction control switch on the dashboard.
• Sub-step 2: Test the switch with a multimeter to ensure it functions correctly (it should show continuity when pressed).
• Sub-step 3: Replace the switch if it is faulty.

5. Update Firmware

• Sub-step 1: Connect the vehicle to Wi-Fi and check for firmware updates via the Tesla app or vehicle settings.
• Sub-step 2: Follow the prompts to install any available updates.

6. Battery Check

• Sub-step 1: Inspect the 12V battery for signs of wear or damage.
• Sub-step 2: Use a multimeter to measure the voltage; it should be above 12.4V.
• Sub-step 3: Replace the battery if voltage is low or it shows signs of failure.
