Procedure

1. Locate the OBD-II port under the dashboard and plug your VCI adapter in.
2. Turn the car on, but do not start the engine. If the Porsche has a start/stop button, press it without pressing the brake pedal.
3. Turn on your scanner and select the “Diagnostic” icon on the home screen.
   
4. Select the Porsche model. Depending on the scanner, you will also need to select the module you want to diagnose. For example, you can choose transmission, ABS, and SRS modules. Remember, you will need a Porsche scanner to access these models.
5. Scroll to Read Fault Codes. Write down all the codes. If codes are in Stored status, go to the next step to clear them. If codes are in Present/Current status, you must fix the problem before clearing those fault codes.

A generic OBD-II scanner can diagnose a Porsche check engine light, but problems related to the airbag, transmission, ABS, and other systems require a more advanced OBD-II scanner, like the YOUCANIC scanner, which is compatible with most Porsche models made after 1996.

Just clearing the DTCs often will not solve the problem. These codes are meant to inform you of a problem in your Porsche. Fix what is causing the problem before clearing the code. If you need more help scanning your Porsche with a YOUCANIC scanner, read our full-system diagnostics guide.
