NOTE:
If there is trouble in more than 2 places, the fault indication will be for the lowest code number first. Even if the problem is corrected during indication, 1 cycle will be indicated. The ECA has a built-in, fail-safe mechanism. If a malfunction occurs during driving, the ECA will operate on fixed values. Driving performance, however, will be affected.
