YMOBD

YMOBD YMOBD is a powerful automotive diagnostic app for Android, supporting real-time engine monitoring, DTC fault detection, freeze-frame data capture, and maintenance reminders to help troubleshoot and plan service.

YMOBD

YMOBD, created by Shenzhen Yuming, is a dedicated mobile application for automotive diagnostics. It helps you pinpoint vehicle problems and troubleshoot effectively with a broad set of tools designed to support both everyday drivers and experienced mechanics.

One of YMOBD’s key strengths is its ability to work across many car makes and models, giving it flexibility for different vehicles. It presents detailed diagnostic output so you can recognize issues faster and make smarter repair decisions.

The app features a beginner-friendly layout and a guided diagnostic flow. Instead of leaving you to guess, it leads you through each step with clear on-screen visuals, making the process easier to follow even if you’re new to car diagnostics.

YMOBD also supports real-time monitoring. You can track important metrics such as engine RPM, fuel consumption, vehicle speed, water temperature, and more—so performance concerns become visible as they happen, helping you respond proactively.

Beyond diagnostics, YMOBD includes maintenance reminders and service alerts. By scheduling routine tasks inside the app, you can help extend vehicle lifespan and reduce the chances of costly repairs later.

Features

• Freeze frame: When an emission-related trouble code is triggered, the ECU captures and stores the relevant data at the moment the code appears.
• Dashboard: Collects engine data in real time (including speed, water temperature, voltage, fuel consumption, and more). Includes two display themes—day and night—and supports a HUD display mode.
• DTC monitoring: Reads the current vehicle’s diagnostic trouble code information and provides professional guidance for the detected faults.



• Fault indicator detection (MIL): Monitors and detects engine system faults through the MIL.



• Monitor status: Shows monitoring status after DTCs are cleared, including whether tests have run at least once during each trip.
• Travel analysis: Logs every driving session, then summarizes driving mileage, average fuel consumption, driving time, driving speed, and other related data.
• Performance testing: Lets you run DIY-style custom tests for acceleration and braking performance (and related distance checks), then generates a test report.
• Oxygen sensor test results: Provides access to in-vehicle oxygen sensor monitoring test results.
• Component/system test results: Shows results from On-Board Diagnostic monitoring tests for specific components or systems.

Highlights

• Simple operation: Designed for easy use, making it suitable for car owners at any experience level.
• Accurate data: Delivers precise, real-time engine data such as engine speed, ignition timing, water temperature, and fuel consumption.



• Bluetooth connectivity: Connects to and communicates with an OBD adapter via Bluetooth for smooth data collection and monitoring.
• HUD display function: Offers a head-up display (HUD) with day and night options for easier viewing while driving.
• Professional fault-code solutions: Reads and analyzes fault codes, then suggests expert-level solutions for the issues detected.
• Comprehensive analysis & reports: Records and analyzes your driving activity to provide insights like mileage, average fuel use, drive time, and speed. Also includes performance test analysis for acceleration and braking, with detailed reports.
