Error code list

Use the list below to help you find the reasons of failures. The number represents the order of failure reason
possibility. Check each part according to the order and replace it when necessary
Caution
When performing DTC check in the inspection mode, if one DTC appears, check the corresponding
circuit system of code listed in the list below
