    Tip:

    • Make sure to save freeze frame data because the data is necessary for performing simulation tests.

    • For the hybrid control system, there are many DTCs, many of which can be stored due to a single malfunction. As a result, in some of the diagnosis procedures an instruction is provided to check for other DTCs and their corresponding INF codes. By following the diagnosis path based on the combination of output DTCs and INF codes, it is possible to narrow down the problem early and avoid unnecessary diagnosis.
