What is a car code reader?
An automobile code reader is a handheld device that tells you why your check light is on. Thus, some people may name it as a check engine light reader. This type of car problem scanner helps you to troubleshoot the entire vehicle status.These devices are quite handy because the check engine light only tells you that something is wrong with the car. It doesn’t tell you what the problem is. Only a mechanic or the best car code reader can tell that to you.
Connect an automotive code reader to an OBD connector and it will read the code for you. You can search for the code or ask a professional to help you understand it. Here’s what a vehicle code reader can do:
Read trouble codes
Clear codes
View some basic PIDs
Check and reset readiness monitors and more
