Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, cleaning supplies (brake cleaner, cloth)
Ensure the vehicle is parked on a level surface, and turn off the engine.
Disconnect the negative battery terminal to reset the vehicle's electronic systems.

2. Resolve Underlying Issues

Error Code Resolution:
- Connect the OBD-II scanner and retrieve any stored error codes.
- Address any faults indicated by the error codes, such as replacing faulty sensors or correcting wiring issues.

3. Clean and Inspect Components

Wheel Speed Sensors:
- Locate the wheel speed sensors at each wheel hub.
- Clean the sensors with brake cleaner and a cloth to remove debris.
- Inspect wiring and connectors for any signs of wear or damage.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, top it up with the recommended brake fluid type (DOT 4 for most Porsches).
Recheck for any signs of leakage in the brake system.

5. Battery Voltage Check

Use a multimeter to measure the vehicle's battery voltage.
If the voltage is below 12.4 volts, recharge or replace the battery as necessary.

6. Reset the System

Reconnect the negative battery terminal once all checks and repairs are complete.
Start the engine and allow it to idle for a few minutes.
Perform a short test drive to allow the traction control system to recalibrate.
