Functional All Modes of OBDII Diagnostics This tool works on most OBDII or CAN protocol compliant vehicles, including 1996 and newer US-based, 2000 and newer EU-based, and Asian cars. It reads and clears engine-related trouble codes from the vehicle’s ECU (Electronic Control Unit) via the check engine light, monitors readiness status, displays live data, shows freeze frame data, and supports all 10 standard OBDII diagnostic modes for accurate and efficient diagnostics: Mode 01: Request current powertrain diagnostic data Mode 02: Request freeze frame information Mode 03: Request emissions-related diagnostic trouble codes Mode 04: Clear or reset emissions-related diagnostic information Mode 05: Request oxygen sensor monitoring test results Mode 06: Request on-board monitoring test results for specific systems Mode 07: Request emission-related diagnostic trouble codes detected during the current or last completed driving cycle Mode 08: Request control of on-board system, test, or component Mode 09: Request vehicle information Supported Protocols: 1.
