ChevroSys Scan Pro is an ad-free OBD2 diagnostic app for Chevrolet and GM-family vehicles. Find out why the Check Engine Light is on, read and clear trouble codes, and go beyond generic OBD2 by scanning the Engine, ABS, SRS (airbag) and Transmission (TCM) modules. It works with a Bluetooth or Wi-Fi ELM327-type OBD2 adapter (sold separately).
★ PRO FEATURES
• No ads, ever
• Built-in DTC database with over 13,000 trouble codes, including Chevrolet/GM-specific codes (the Free version has fewer than 8,000)
• Clean, professional interface designed for daily workshop use
★ OBD2 (ALL OBD2-COMPLIANT VEHICLES)
• Read and clear Stored, Pending and Permanent DTCs
• Freeze Frame data for the code that triggered the Check Engine Light
• Live Data with all PIDs supported by your vehicle, in US or metric (SI) units
• I/M Readiness (smog test) status and MIL state
• Mode $06 on-board monitor test results
• Mode $05 oxygen sensor test results
• Vehicle information: VIN, Calibration ID, CVN and IPT
★ MODULE SCANS FOR CHEVROLET & GM
• Engine (PCM/ECM): read and clear DTCs
• Transmission (TCM): read and clear DTCs
• ABS: read and clear DTCs
• SRS / airbag: read and clear DTCs
The app detects the vehicle's protocol automatically and shows each module's codes with a plain-English description.
★ SUPPORTED PROTOCOLS
GMLAN CAN, CAN (ISO 15765-4), VPW (SAE J1850), ISO 9141-2, KWP2000 (ISO 14230-4).
Module coverage depends on the vehicle model, year and the adapter used.
★ COMPATIBLE ADAPTERS
Tested with OBDLink MX, Vgate Bluetooth, ELM327 v1.5 Bluetooth and ELM327 Wi-Fi adapters. Other genuine ELM327-compatible adapters (OBDLink, Kiwi, Vgate, BAFX) should also work.
Note: many low-cost clones that report "ELM327 v2.1" are incomplete and may only support basic OBD2 functions. For reliable manufacturer-module scans, use a quality adapter.
★ HOW TO USE
1. Plug the adapter into the OBD2 port (usually under the dashboard).
2. Turn the ignition on and pair via Bluetooth or join the adapter's Wi-Fi.
3. Open the app, connect, and choose OBD2, Engine, ABS, SRS or TCM.
Always follow the repair procedure for your vehicle. Clearing codes does not repair the fault; resolve the cause first.
