How to Use a CAN OBD2 Memoscan: Your Complete Guide

Understanding how to use a CAN OBD2 Memoscan can empower you to diagnose and potentially fix your car troubles. This comprehensive guide will walk you through every step, from connecting the device to interpreting the codes, ensuring you can confidently use your Memoscan like a pro.

Connecting Your Memoscan OBD2 Scanner

Before you begin, make sure your vehicle is parked on a level surface and the ignition is turned off.

Locate the OBD2 port: This 16-pin connector is usually located beneath the steering wheel on the driver’s side.
Connect the Memoscan: Insert the scanner’s connector firmly into the OBD2 port.
Turn the ignition ON: Don’t start the engine yet. This powers up both the scanner and your car’s computer.
Turn on the Memoscan: The device should automatically power on and connect to your vehicle’s system.

Navigating the Memoscan Interface

The Memoscan boasts a user-friendly interface that simplifies the diagnostic process. Familiarize yourself with these key elements:

Display Screen: Shows codes, data, and navigation menus.
Navigation Buttons: Used to scroll through menus and select options.
Enter/OK Button: Confirms selections and initiates actions.
Escape/Back Button: Returns to previous menus or cancels actions.

Reading and Understanding OBD2 Codes

Once connected, the Memoscan will automatically scan for and display any trouble codes stored in your vehicle’s computer. These codes are standardized by the Society of Automotive Engineers (SAE) and consist of a five-character alphanumeric string.

The first character indicates the system:
- P: Powertrain (engine and transmission)
- B: Body
- C: Chassis
- U: Network & Communication
The remaining characters pinpoint the specific issue.

Refer to the Memoscan CAN OBD2 manual or a reliable online database for a detailed explanation of each code.

Clearing Trouble Codes

After addressing the underlying issue that triggered the code, you can use the Memoscan to clear it from the vehicle’s memory:

Access the “Clear Codes” function: This is usually found in the main menu.
Confirm the action: The Memoscan will prompt you to confirm the code clearing.
Verify the code is cleared: Rescan your vehicle’s system to ensure the code is gone.

Note: Clearing codes without fixing the problem is only a temporary solution. The code will reappear if the issue persists.

Beyond Basic Diagnostics: Advanced Features of the Memoscan

Memoscan offers more than just code reading and clearing. Depending on your model, you can access advanced features like:

Live Data Stream: View real-time data from various sensors, such as engine RPM, coolant temperature, and oxygen sensor readings.
Freeze Frame Data: Capture a snapshot of the vehicle’s operating conditions at the time a fault code was stored.
Component Testing: Activate specific components, such as fuel injectors or solenoids, to test their functionality.

For detailed instructions on using these advanced features, consult the CAN OBD2 manual for your specific device.

Conclusion

Mastering the use of a CAN OBD2 Memoscan opens a new world of car maintenance. This powerful tool allows you to identify and understand car problems, saving you time and potentially costly repairs. Remember, however, that while the Memoscan is an invaluable diagnostic aid, it’s always best to consult a qualified mechanic for complex issues.
