The best OBD-II scanners in 2022 | Wilson's Guide
1. OBDII Mode 1 - On Board Diagnostics II (OBDII) Mode 1 is designed to test emissions from vehicles that are equipped with a CAN-Bus system. This mode can be used to check the emission control systems of any vehicle.
2. OBDII Mode 2 - On Board Diagnostics (OBD) Mode 2 is designed to test emissions only from vehicles that are equipped on a CAN-Bus system, but not all vehicles have this feature. This mode can be useful if your vehicle has been involved in an accident and the police want to know what happened.
3. OBDII Mode 3 - On Board Diagnostics I (OBDI) Mode 3 is designed to test emissions ONLY from vehicles that are equipped without a CAN-Bus system and therefore cannot perform diagnostic tests. This mode is not recommended for use unless you are specifically trained to do so.
4. OBDII Mode 4 - On Board Diagnostics III (OBDIII) Mode 4 is designed to test emissions FROM vehicles that are equipped with both a CAN-Bus system AND a CAN-Bus system that is capable of performing diagnostic tests. This mode can be very helpful if you need to diagnose problems with your vehicle's emissions system.
5. OBDII Mode 5 - On Board Diagnostics IV (OBDIV) Mode 5 is designed to test emissions FOR vehicles that are equipped with an engine management computer. This mode is not compatible with vehicles that are equipped with either a CAN-Bus system or a CAN-Bus system capable of performing diagnostic tests, since these modes rely on the information provided by the engine management computer.
6. OBDII Mode 6 - On Board Diagnostics V (OBDV) Mode 6 is designed to test emissions for vehicles that are equipped with sensors that monitor the air/fuel ratio and exhaust gas recirculation. This mode is not intended for use with vehicles that are equipped WITH a CAN-Bus system OR a CAN-Bus system able to perform diagnostic tests.
