OBD Scanner ELM327: GaragePro

Vehicle diagnostics for owners and workshops

OBD Scanner ELM327: GaragePro connects to compatible cars, motorcycles and heavy vehicles through common OBD2 scanners, including ELM327 adapters. It is aimed at vehicle owners, DIY mechanics and repair shops that need more than a basic check-engine reading.

The app can scan several vehicle systems, including the engine, ABS, airbag or SRS, transmission, EPS, BCM, HVAC and instrument cluster. It reads fault codes and vehicle information, while explanations and scan reports help users understand what a code may indicate.

Live readings and service functions

GaragePro displays real-time sensor data such as engine speed, vehicle speed, coolant temperature and fuel trim. More than 100 data points can be monitored, viewed in graphs and exported for further analysis. The app also supports freeze-frame data, VIN and calibration details, smog checks and code clearing after repairs.

• Mode 06 readings for items such as misfires, catalysts, EVAP, EGR, VVT and particulate filters
• Service actions including oil resets, throttle resets and steering-angle resets
• Selected special functions such as injector coding, DPF regeneration, ABS bleeding and actuation tests
• Additional resets and learning procedures for supported vehicle systems

What the grade says

Grade: C — Its 3.20 average from 6,780 ratings places GaragePro in the adequate range rather than the top tier. The feature list is broad, but the practical results will depend on the vehicle, its control modules and the connected scanner. Users should check that their vehicle supports the required diagnostic or service function before relying on it for a repair.

At a glance

GaragePro is published by CaRPM in Auto & Vehicles and has recorded 1,000,000+ installs. It suits people who want live data and deeper module coverage alongside ordinary OBD fault-code work, provided their vehicle and adapter are compatible.
