DATA LIST / ACTIVE TEST
NOTICE:
- In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.
- When diagnosing symptoms such as hesitation, rough idle, or other small symptoms using vehicle control history, compare data extracted from the same vehicle model in the same conditions and make sure to analyze all data in its entirety before making a diagnosis.
