√ Vehicle Coverage: most 1996 and newer OBDII & CAN vehicles across the globe. √ Full OBD2 Modes Test: turn off the CEL; help pass the smog test; detect most emission-related car issues (graphic live stream, freeze frame data, o2 sensor test, etc.). √ Patented One-click I/M Readiness: for fast and easy emission readiness check.

√ Multimeter (AVOmeter): diagnose the vehicle electrical system (DC or AC voltage, continuity, and current) to simplify the troubleshooting. √ Battery Health Tester: load-free testing of most 12V batteries health status (Type: Regular, AGM, AGM/Spiral, Gel; Rating: CCA, CA, MCA, JIS, DIN, SAE, IEC, EN). √ Starter Tester: help predict if the battery will fail to start a vehicle.

√ Charging System Tester: check if the output voltage and the charging current is normal. √ More: data record and review; multilingual menu (EN, ES, FR ...), DTC definition; internet update; data printable via PC. Circuit Test (as a Multimeter / AVOmeter) √ Test the voltage in both AC or DC components (if > 30V, the scan tool may be damaged).

√ Test the resistance between two circuit points (if > 50 ohm, it will display 0L). √ Measure the flow of current between 0A~20A (if >20A, the scan tool may be damaged). √ Can test the diodes (connect the probes to battery terminals correctly).

Battery Test (diagnose battery health, starter, and charging system status) Connect this OBD2 scanner to your vechile via DLC port, or contact the probes to battery’s terminals. You can also use it to test the battery health, starter, and charging system status. √ Battery Health Test √ Starter Status Test √ Charging System Test All Modes OBDII Scanner √ Read DTCs √ Clear DTCs √ View dynamic Live Data √ Display I/M Readiness Status √ Show Freeze Frame Data √ O2 Sensor Test √ EVAP Test √ Access to on-Board Diagnostic Monitoring Test Results √ Retrieve vehicle information (VIN, CID, and CVN) √ Read generic (P0, P2, P3, and U0) and manufacturer specific (P1, P3, and U1) codes
