HINT:
- 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.
By following the diagnosis path based on the combination of output
DTCs, it is possible to narrow down the problem early and avoid
unnecessary diagnosis.
