Before you buy an autonomous vehicle odometer, you need to understand that there are different types out there, and the one you choose should meet your needs and, most importantly, be compatible with your vehicle. Some code readers are necessary. Scans, reads, and interprets Diagnostic Trouble Codes (DTCs) from the on-board computer. These DTCs are numbers that are stored in the vehicle’s computer when a problem is detected. By scanning DTCs, a vehicle code reader can help determine the cause of a vehicle problem.
There are also some very high-quality ones with additional equipment. Not only do they check and interpret DTCs but they can clear these codes, reset the check engine light, and get live data from the car’s computer. In addition, some advanced code readers have their own smartphone apps. This allows smartphone users to easily share DTCs and other diagnostic data with mechanics or view the status from their on-board computer at any time as long as the code reader is connected to the vehicle.
