Step-by-Step Guide to Clearing Codes
Clearing codes with the Bosch 1150 is a straightforward process. Follow these steps to effectively erase diagnostic trouble codes from your vehicle’s computer:
-
Locate the OBD2 Port: First, you need to find your vehicle’s OBD2 port. It’s typically located under the dashboard on the driver’s side. Refer to your vehicle’s owner’s manual if you are unsure of its exact location.
-
Connect the Bosch 1150 Scanner: Plug the Bosch 1150 scanner into the OBD2 port. Ensure it is firmly connected.
-
Turn Ignition to ‘ON’ (Engine OFF): Turn your vehicle’s ignition key to the ‘ON’ position. This powers up the car’s electronics, including the OBD2 system, but do not start the engine.
-
Power On the Scanner and Navigate to ‘Codes’: The Bosch 1150 should power on automatically. Use the scanner’s navigation buttons to find the ‘Codes’ or ‘Diagnostic Trouble Codes’ option in the main menu.
-
Read the Diagnostic Trouble Codes (DTCs): Before clearing any codes, it’s advisable to read them first. Select the option to ‘Read Codes’. The scanner will display any stored DTCs. Note these codes down; they can be helpful for future diagnosis or if the issue persists. Understanding these codes can give you insight into the problem your vehicle is experiencing.
-
Select ‘Erase Codes’ or ‘Clear Codes’: Once you have reviewed the DTCs, navigate to the ‘Erase Codes’ or ‘Clear Codes’ option in the scanner menu. The wording may slightly vary depending on the exact software version of your Bosch 1150.
-
Confirm Code Clearing: The scanner will likely ask for confirmation before clearing the codes. Follow the on-screen prompts to confirm that you want to erase the DTCs.
-
Verify Codes are Cleared: After confirming, the scanner will process the request and clear the codes. To ensure the codes have been successfully cleared, you can re-scan for codes using the ‘Read Codes’ function again. If the process was successful, no DTCs should be displayed.
-
Disconnect the Scanner: Once you have verified that the codes are cleared, turn the ignition off and disconnect the Bosch 1150 scanner from the OBD2 port.
Important Considerations After Clearing Codes
- Address the Underlying Issue: Clearing codes only turns off the check engine light; it does not fix the underlying problem that triggered the code in the first place. It is crucial to diagnose and repair the issue. If the problem persists, the check engine light will likely reappear, and the same codes or new ones may be triggered again.
- Check Engine Light Behavior: After clearing the codes, observe if the check engine light comes back on. If it does, it indicates that the problem is still present.
- Bosch Discontinuation Note: Keep in mind that the Bosch OBD 1150 line has been discontinued. While it remains a functional tool, software updates and support may be limited.
Conclusion
The Bosch 1150 OBD2 scanner is a valuable tool for car owners who want to take a proactive approach to vehicle maintenance. Knowing how to clear codes is a fundamental aspect of using this device. By following these steps, you can effectively clear diagnostic trouble codes and gain a better understanding of your vehicle’s health. Remember, clearing codes is just one step in vehicle maintenance; proper diagnosis and repair of the underlying issues are essential for keeping your car running smoothly and efficiently.
