Reading and Clearing Diagnostic Trouble Codes

One of the primary functions of the Actron Cp9135 Auto Code Reader is to read and clear diagnostic trouble codes (DTCs) that may be causing your check engine light to illuminate. When your check engine light comes on, it is an indication that there is a problem with your vehicle that needs to be diagnosed. By using the Cp9135 code reader, you can easily retrieve the DTCs and gain insight into the issue.

To read the DTCs, start by locating the data/diagnostic link connector (DLC) on your vehicle. It is typically located within reach of the driver’s seat, either under the dashboard or in the engine compartment. Plug the Cp9135 code reader into the DLC, and then turn the ignition key to the “On” position without starting the engine.

Follow the on-screen LCD menu display on the code reader, using the buttons on the unit face to navigate through the different options. When you are ready, press the “Enter” button to initiate the DTC reading process. The code reader will communicate with your vehicle’s onboard computer, retrieve and display any stored trouble codes.

Once the DTCs are displayed, you can use the code reader’s menu options to clear the codes, allowing you to reset the check engine light. It’s important to note that clearing the codes does not necessarily fix the underlying problem. However, it can provide a temporary solution if you have addressed the issue and want to turn off the check engine light.
