Moreover, what is a fault code?
Diagnostic trouble codes (or fault codes) are codes that are stored by the on-board computer diagnostic system. These are stored in response to a problem found in the car by the system.
Also, how do you tell if OBD codes have been cleared? Instructions
- Turn the key to ON position. Do not start the car.
- Locate the OBD-II port under the dashboard and plug in the OBD2 scanner.
- The scanner should power on once connected to the OBDII port.
- Scroll down to I/M Readiness menu and select it.
- Look at all the systems.
Keeping this in view, what is a stored OBD code?
Active codes (aka STORED codes) are live codes or malfunctions that are keeping your Check Engine Light on. Just because your Check Engine Light is off doesn't mean the code or malfunction disappeared, it just means that the code setting conditions haven't occurred for two or more operations of the vehicle.
How do you read codes?
The best way I've ever discovered to read and understand someone else's code is to:
- Find one thing you know the code does, and trace those actions backward, starting at the end. Say, for example, you know that the code you're viewing ultimately creates a file with a list of movie titles.
- Rinse and repeat.
