The Autophix OM126P is an enhanced OBD2 (On-Board Diagnostics) OBD II scanner designed to help car owners and technicians diagnose vehicle problems quickly and accurately. This comprehensive guide provides a detailed overview of the OM126P, covering its features, functionality, and how to use it effectively.
Understanding OBD II and Diagnostic Trouble Codes (DTCs)
On-Board Diagnostics II (OBD II) is a standardized system that monitors emission control systems and key engine components in vehicles. When a problem is detected, the OBD II system illuminates the Malfunction Indicator Lamp (MIL) on the dashboard, often accompanied by a “Check Engine” or “Service Engine Soon” message. The system also stores Diagnostic Trouble Codes (DTCs), which are five-digit alphanumeric codes that pinpoint the specific problem area.

- Locate the 16-pin Data Link Connector (DLC) under the dashboard.
- Connect the OM126P’s cable to the DLC.
Reading and Erasing DTCs
The OM126P allows you to quickly read and erase stored DTCs. This enables you to identify the problem and clear the codes after repairs are completed. The scanner provides detailed code definitions to help you understand the issue.
Viewing Live Data Stream
The Data Stream function displays real-time sensor data from the vehicle’s engine and other systems. This information can be crucial for diagnosing intermittent problems or monitoring specific parameters. You can view data in various formats, including text and graphs. Choose specific items to monitor for a customized view.
I/M Readiness and Freeze Frame Data
The I/M Readiness function checks the status of the vehicle’s emission monitors. This is essential for ensuring your car passes emissions tests. The Freeze Frame function captures a snapshot of vehicle data at the moment a fault code is set, providing valuable context for diagnosis.
O2 Sensor and On-Board Monitor Tests
The OM126P can perform O2 sensor tests and access the results of on-board monitor tests conducted by the vehicle’s computer. This helps pinpoint issues with the oxygen sensors and other emission-related components.
