All US-manufactured cars since 1995 have a standardized diagnostic port, allowing access to diagnostic trouble codes (DTCs). For the Porsche Boxster 986, this OBD II port is located above the left knee of the driver. A 986 Scan Tool is essential for reading and understanding these codes. This article will discuss various options available for diagnosing your Boxster.
Options for 986 Scan Tools
Several tools can read the OBD II codes on your Porsche 986.
Generic OBD II Scanners
Affordable options like the Actron CP9135 (around $100) offer basic code reading and resetting capabilities. Many auto parts stores, such as AutoZone and Pep Boys, also provide free code reading services using generic OBD II scanners. These tools are sufficient for reading and clearing many common engine-related codes (CELs).
Porsche Specific Scan Tools
For more in-depth diagnostics, Porsche-specific scan tools are necessary.
-
Durametric Software: This software, paired with a compatible hardware adapter (around $287), offers advanced functionality for Porsche vehicles. It connects to a Windows laptop via USB and can access Porsche-specific codes, including non-engine related codes. Durametric software can also activate certain components for diagnostic purposes, exceeding the capabilities of generic OBD II readers. However, it’s primarily designed for Porsche vehicles.
-
Porsche System Tester 2 (PST2) and PIWIS: These professional-grade tools are used by Porsche dealerships and specialized independent mechanics. They provide comprehensive diagnostic capabilities and access to detailed technical information. However, these systems cost thousands of dollars.
Understanding Porsche 986 Fault Codes
Once you’ve retrieved the codes using a 986 scan tool, understanding their meaning is crucial. A valuable resource for Porsche fault codes is Renntech.org. Their “OBDII P-Codes” document under “Online Docs” provides a list of DME (Digital Motor Electronics) Engine Codes specific to the Boxster 986. Remember to refer to the correct DME version for your model year: DME 5.2 for 1997-1999 and DME 7.2 for 2000-2004.
Importance of Diagnostics When Buying a Used 986
When purchasing a used Porsche Boxster 986, a pre-purchase inspection using a 986 scan tool is highly recommended. A simple code scan can reveal potential issues and provide valuable insights into the car’s history. Any seller reluctant to allow a scan should raise concerns.
Conclusion
A 986 scan tool is an invaluable tool for any Porsche Boxster owner. From basic code reading and clearing to in-depth diagnostics, selecting the right tool depends on your needs and budget. Understanding the codes and utilizing resources like Renntech.org will help you maintain and troubleshoot your Boxster effectively. Don’t hesitate to use a scan tool during a pre-purchase inspection for a used 986.
