How to read and clear codes
1 · Read the code
- Find the 16-pin OBD socket (see "Where is the socket" in the scanner guide on the Warning lights page).
- Plug in an OBD-II scanner and turn the key to ON (engine off).
- Read and write down every stored code, with its freeze-frame data if the scanner shows it.
2 · Fix, then clear
- Fix the cause first. Clearing a code does not fix the fault.
- Clear the code with the scanner.
- Test-drive. If the light comes back, read the code again.
