For car owners and DIY mechanics, understanding your vehicle’s health is crucial. The Cen-Tech 60694 OBD2 EOBD scanner is a popular entry-level tool that provides access to your car’s onboard diagnostic system. This article will explore the features, benefits, and limitations of the Cen-Tech 60694 scanner, helping you determine if it’s the right tool for your automotive diagnostic needs.
Understanding OBD2 and EOBD Systems
Before diving into the specifics of the Cen-Tech 60694, it’s important to understand the underlying technology it utilizes: OBD2 and EOBD.
OBD2, or On-Board Diagnostics II, is a standardized system implemented in most cars sold in the United States from 1996 onwards. It monitors various vehicle systems, including emissions, engine, transmission, and more. When the system detects an issue, it generates a Diagnostic Trouble Code (DTC) and illuminates the Check Engine Light (CEL) on your dashboard.
EOBD, or European On-Board Diagnostics, is the European equivalent of OBD2 and is mandatory for petrol vehicles from 2001 and diesel vehicles from 2004. EOBD is largely harmonized with OBD2, meaning scanners like the Cen-Tech 60694 that support OBD2 generally also support EOBD protocols.

Features of the Cen-Tech 60694 OBD2 Scanner
The Cen-Tech 60694 is designed as a basic, user-friendly OBD2 scanner, ideal for beginners and those needing to quickly read and clear engine codes. Key features include:
- Read Diagnostic Trouble Codes (DTCs): The primary function of the 60694 is to read DTCs. These codes are numerical representations of detected faults within the vehicle’s systems. The scanner displays these codes, giving you an initial indication of the problem.
- Clear Diagnostic Trouble Codes (DTCs): Once you’ve addressed the issue causing the DTC, the 60694 allows you to clear the codes and turn off the Check Engine Light. However, it’s crucial to fix the underlying problem first; simply clearing the code without repair will only result in the light reappearing.
- Live Data Stream: The scanner can display live data parameters from the vehicle’s sensors. This data can include engine RPM, coolant temperature, vehicle speed, and more. Monitoring live data can be helpful in diagnosing intermittent issues or verifying sensor readings.
- MIL Status: The 60694 indicates the status of the Malfunction Indicator Lamp (MIL), commonly known as the Check Engine Light. This quickly confirms whether the CEL is currently active.
- Generic OBD2 Compatibility: The Cen-Tech 60694 supports generic OBD2 protocols, making it compatible with a wide range of vehicles manufactured from 1996 onwards that adhere to OBD2 standards.

Benefits of Using the Cen-Tech 60694
For everyday car owners, the Cen-Tech 60694 offers several advantages:
- Cost-Effective: Compared to professional-grade scanners, the 60694 is very affordable, making it accessible to budget-conscious individuals.
- User-Friendly: Its straightforward interface and simple operation make it easy to use, even for those with limited automotive knowledge.
- Quick Diagnostics: The scanner allows you to quickly identify the cause of a Check Engine Light, saving you time and potential unnecessary trips to a mechanic for initial diagnosis.
- DIY Repairs: By understanding the DTCs, you can research and potentially perform minor repairs yourself, saving on labor costs.
- Preventative Maintenance: Monitoring live data can help you identify potential issues early before they become major problems.
Limitations of the Cen-Tech 60694
While the Cen-Tech 60694 is a useful tool, it’s important to be aware of its limitations:
- Basic Functionality: It’s a basic scanner primarily focused on reading and clearing generic OBD2 codes. It lacks advanced features found in professional scanners, such as manufacturer-specific codes, bidirectional controls, and advanced diagnostics.
- Limited Data Parameters: While it offers live data, the range of parameters may be limited compared to more advanced scanners.
- No Advanced Tests: The 60694 typically doesn’t support advanced tests like actuation tests or module programming.
- Dependence on Code Libraries: The scanner relies on built-in code libraries for DTC definitions. While generally accurate, these definitions can sometimes be generic and may not pinpoint the exact root cause of the problem in all cases.
