Big-shop answers from a tool that fits your glovebox.
Five core strengths put genuine garage-grade diagnostics in the palm of your hand — no subscriptions, no laptop, no guesswork. Plug into your OBDII port and the MA100 does the talking.
Complete OBDII/EOBD Diagnostics
Accesses all 10 standard test modes to accurately pinpoint engine malfunctions, turn off the Check Engine Light (MIL), and reset monitors.
Real-Time Data & Graphing
Captures live PCM data and displays it as clear on-screen graphs, giving you instant feedback on sensor and system behavior.
Intelligent Battery Assessment
Monitors real-time vehicle battery voltage to track charging system health and detect potential electrical failures before they leave you stranded.
Lifetime Free Software Updates
Easily update the MA100 from your PC using our official update tool to gain new features, expand compatibility, and keep pace with evolving vehicle data.
100% Plug-and-Play Efficiency
Power is drawn directly from your vehicle’s OBDII port. No batteries, chargers, laptops, or software installation required.
One pocket tool, four jobs done.
The MA100 is a focused OBDII/EOBD engine & emission specialist — tap through its four core jobs to see exactly what it reads from your car’s port.
See what your engine is doing — the moment it does it.
Turn raw numbers into a picture you can actually read. The MA100 streams live module data and draws it on screen so intermittent faults have nowhere to hide.
High-Speed Refresh Rate
Monitors Powertrain Control Module (PCM) telemetry with minimal latency, ensuring immediate capture of irregular parameter spikes.
Monochrome Visual Graphing
Translates numeric live streams into clean, easy-to-read graphical data lines for structural fault tracing.
Vital Parameter Tracking
Monitors engine RPM, vehicle speed, coolant temperature, mass air flow (MAF) rates, fuel trim metrics, and oxygen sensor behaviors simultaneously.
Every code read. Every code explained. Every code cleared.
From the first warning light to the final reset, the MA100 reads, decodes and clears trouble codes — then captures the exact conditions behind them so you fix the cause, not just the symptom.
Universal Code Retrieval
Instantly reads and clears generic (P0, P2, U0) and manufacturer-specific (P1, U1) powertrain and network codes, plus pending and permanent trouble codes.
Smart Freeze Frame Captures
Automatically logs a snapshot of key engine parameters at the moment an emission-related fault is triggered.
Built-in DTC Lookup Library
Includes an on-board database of trouble-code definitions, so you can troubleshoot instantly without an internet connection.
Emissions Test Readiness (I/M Status)
Checks whether your vehicle’s emission monitors have run and are ready, so you know if it will pass an emissions / smog test.
O2 Sensor & On-Board Monitoring
View oxygen sensor test results and on-board monitoring test results for non-continuously monitored systems (Mode 6).
EVAP System Leak Testing
Commands the vehicle’s computer to initiate a targeted leak test on the evaporative emission control system.
Instant Vehicle Info Retrieval
Reads factory data including the Vehicle Identification Number (VIN), Calibration ID, and Calibration Verification Number (CVN).
Catch a dying battery before it strands you.
Every time you plug in, the MA100 reads your battery and charging-system voltage in real time — the first sign of trouble most drivers never see until the car won’t start.
If it speaks OBDII, the MA100 speaks its language.

Everything you need to know.
No, the iCarzone MA100 is completely battery-free and 100% plug-and-play. It draws its operating power directly from your vehicle’s 12V battery through the OBDII diagnostic port. It turns on automatically as soon as it is plugged in.
No. The MA100 is a dedicated Engine and Emission scanner. It accesses the Powertrain Control Module (PCM) to read/clear engine fault codes and turn off the Check Engine Light (MIL). It does not diagnose advanced proprietary systems like ABS, SRS, Transmission, or Electronic Parking Brake (EPB).
All software updates for the iCarzone MA100 are 100% free for life with no annual fees or hidden subscriptions. You can easily download the latest firmware via our official update tool to expand vehicle databases, optimize performance, and unlock new software features.
A linking error usually means the tool cannot establish communication with the vehicle’s computer. Please check the following:
- Ensure your vehicle’s ignition is turned to the ON position (or start the engine).
- Check that the OBDII connector is securely plugged into the vehicle’s port.
- Verify that your vehicle is fully OBDII compliant.
