Understanding the Actron CP9175
The Actron CP9175 is an older model OBD2 scanner, but it remains a reliable option for reading and clearing diagnostic trouble codes (DTCs) in most OBD-II compliant vehicles manufactured after 1996. It’s a handheld device with a simple interface, making it user-friendly even for beginners. While it might not offer the advanced features of newer scanners, it effectively retrieves and clears basic codes, helping you pinpoint the source of your vehicle’s “Check Engine” light.
Using the Actron CP9175: A Step-by-Step Guide
-
Locate the OBD-II Port: This port is typically found under the dashboard on the driver’s side, often near the steering column.
-
Connect the Scanner: Plug the CP9175’s connector into the OBD-II port.
-
Turn on the Ignition: Turn the ignition key to the “On” position without starting the engine. This powers up the scanner and allows it to communicate with the vehicle’s computer.
-
Read the Codes: The CP9175 will automatically begin scanning for trouble codes. These codes will be displayed on the scanner’s screen. Write down any codes displayed.

Common Actron CP9175 Issues and Troubleshooting
-
Linking Error: If you encounter a “linking error,” ensure the scanner is properly connected to the OBD-II port and the ignition is on. Check fuse #16, as it often powers the OBD-II port and might be blown. Try disconnecting and reconnecting the scanner.
-
No Codes Found: If the scanner doesn’t find any codes but the check engine light is on, there might be a problem with the OBD-II system itself. Consult a professional mechanic.
-
Interpreting Codes: Once you have the codes, you can look them up online or in a vehicle-specific repair manual. Resources like the Actron website or online OBD-II code databases can provide detailed information about each code.

- Live Data Stream: Viewing real-time sensor data.
- ABS and Airbag Codes: Reading codes related to anti-lock brakes and airbags.
- Smog Readiness Tests: Checking if your vehicle is ready for emissions testing.
- Bluetooth Connectivity: Wireless connection to smartphones or tablets for enhanced data analysis.

Conclusion
The Actron CP9175 OBD2 scanner is a useful tool for basic car diagnostics. By understanding its operation and troubleshooting common issues, you can effectively use it to identify and resolve car problems. While newer scanners offer more features, the CP9175 remains a viable option for retrieving and clearing basic trouble codes, particularly for older vehicles like a 1996 Ford Bronco. Remembering to check fuse #16 if encountering connectivity problems can save you significant diagnostic time.
