* When the TCU start up, the counter is set to 0. Meaning the error has not been checked. Upon every successful conformation, or error, the counter
|
||||
* is either decreased or increased. When reaching its negative limit (-128), the DTC is marked as OK. If the counter reaches 127, then the failure
|
||||
* is marked as current, the `env_data_first_occurrence` is written to, and the `drive_cycle_count` is increased by 1. If the `drive_cycle_count` is
|
||||
* now more than 1, indicating this is the 2nd or more time this fault has been triggered, then `env_data_most_recent_occurrence` is also written to,
|
||||
* the TCU is now considered stored and current. If on the next startup, the counter hits -127 (Error is OK now), then the DTC is just marked as `stored`
