Worried About Being Fined for the Emission Exceeding? Most states in US require an emission test for car registration. 70% cars will encounter the smog test. Among those tested cars, over 30% failed the test, which means you cannot get a license plate for it and will be requested to repair any issues. Moreover, a fine will be paid for this. How to pass this inevitable smoke test? Before the test, go to the mechanic for costly diagnosis and repairs or do it yourself with an OBD2 scanner? TOPDON AL300, an excellent OBD2 code reader enables more people to perform pre-inspections for smog tests on their own. By retrieving the I/M Readiness Status and O2 sensor data, this OBD2 scanner checks if emissions-related systems are ready for Inspection and Maintenance testing to avoid the fine and rejection in the inspection. What Should You Do When Your Car Failed the Vehicle Inspection? If your car failed the vehicle inspection, first you need to figure out the reasons for inspection failure. Once you find out the reason, the fix will be much easier and faster. A failed emission test occurs for many reasons. To analyze the vehicle inspection failure, this OBD2 code reader offers various functions for different reasons. ● O2 Sensor Test for O2 Sensor malfunction by retrieving and viewing the test results of O2 sensor monitors; ● I/M Readiness for emission-related parts problems by observing the performance of car’s emission-related systems; ● On-board Monitoring (Mode 6) for on-board monitor issues by retrieving test results for emission-related powertrain components and systems that are not continuously monitored. How to Save Money & Time? In addition to the vehicle inspection, this OBD2 coder reader is also a great help for DIY users to save money and time. With full OBD2 functions, this OBD2 scanner quickly and accurately diagnose various vehicle issues. √ Retrieving VIN (Vehicle Identification NO.): reads and displays the vehicle information for users to save the trouble of looking around for VIN. √ Reading Codes: retrieves both generic (P0, P2, P3, and U0) and manufacturer specific (P1, P3, and U1) codes to identify which section of the emission part has malfunctioned. √ Clearing Codes: erases the retrieved DTCs and other related data after certain repairs to turn off MIL (Malfunction Indicator Light). √ Viewing Freeze Frame: views the vehicle’s operating parameters when a DTC is detected, to quickly locate malfunctions. √ Reading Live Data Stream: displays real-time PID data from ECU in various ways to monitor car issues. Why Not Do It Yourself with an AL300? When your Check Engine Light comes on, you can turn it off with TOPDON AL300.

NOTICE By clearing trouble codes you also clear the readiness status for the individual emission system readiness tests. In order to reset these monitors, the vehicle must be driven through a complete drive cycle with no trouble codes in memory. Amount of time needed for reset vary by vehicle. Do not erase the codes before repairs or services have been performed. Codes will again display if the underlining fault causing the code is not addressed.
