6. How to Use a Mercedes OBD2 Code Reader: A Step-by-Step Guide

Using a Mercedes OBD2 code reader is a straightforward process. Here’s a step-by-step guide:

1. Locate the OBD2 Port: The OBD2 port is typically located under the dashboard, near the steering column. Consult your vehicle’s manual if you’re unsure of its location.
2. Connect the Scanner: Plug the OBD2 scanner into the port.
3. Turn on the Ignition: Turn the ignition key to the “on” position, but do not start the engine.
4. Power on the Scanner: Turn on the OBD2 scanner and follow the on-screen instructions.
5. Read Error Codes: Select the “Read Codes” or “Diagnostic Codes” option on the scanner. The scanner will display any stored error codes.
6. Interpret Error Codes: Use the scanner’s code definition display or consult a repair database to understand the meaning of each error code.
7. Clear Error Codes (Optional): If you have repaired the underlying issue, you can select the “Clear Codes” option to reset the check engine light.

7. Understanding OBD Error Codes

OBD error codes are five-digit alphanumeric codes that provide information about specific issues within your vehicle’s systems. The first character indicates the system affected:

• P: Powertrain (engine, transmission)
• B: Body (airbags, lights, windows)
• C: Chassis (ABS, suspension)
• U: Network (communication systems)

The second character indicates whether the code is generic (0) or manufacturer-specific (1). The remaining characters provide more specific information about the fault.

Example:

• P0300: Random/Multiple Cylinder Misfire Detected

8. The Different OBD Modes Explained

The OBD system is divided into ten different modes, each offering specific functionalities:

Mode	Description
Mode 01	Shows current diagnostic data, sensor data, and parameters in real-time.
Mode 02	Displays freeze frame data (data saved when an error code occurred).
Mode 03	Provides confirmed emission-relevant error codes.
Mode 04	Clears all emission-related data, including error codes and freeze frame data.
Mode 05	Queries lambda probe monitoring test results.
Mode 06	Interrogates systems that are not continuously monitored.
Mode 07	Reads out data that failed during a work cycle but were not sufficient to generate an error code.
Mode 08	Generally not used in Europe.
Mode 09	Accesses special vehicle information, such as the chassis number (VIN).
Mode 0A	Reads out all error codes with the status “permanent DTC”.

9. What is Stored in the Error Memory?

The error memory, part of the control unit, records malfunctions detected by the system. The control unit checks if the measured values received are correct for the proper operation of the vehicle. The errors detected are stored in a non-volatile manner. Each control unit stores its own faults, so there are multiple independent fault memories in the vehicle, and all must be checked for a comprehensive diagnosis.

10. Are All Error Codes Bad?

Not all error codes indicate a serious problem. Some may be random errors or require attention later. Properly understanding error codes can save you panic and expensive workshop visits.

11. How Can You Read Out the Error Memory?

Workshops use diagnostic devices to read fault codes from the fault memory. Depending on the vehicle, all control units may be automatically checked, or individually checked manually. After errors have been read and the reasons fixed, the error memory can be cleared.

12. The Cost of Reading Out the Fault Memory

At a workshop, a scan can cost $25 to $60 or more. If an error is detected and needs immediate correction, those costs can skyrocket. Authorized workshops may read the fault memory for free, with the caveat that any repairs must be undertaken at their facility. Workshops use professional-level diagnostic equipment that costs thousands of dollars, which are not suitable or cost-effective for the average vehicle owner.
