If a task failed to initialize.
A task init function returns with an error.
If an init routine fails, software may not opperate correctly.
If a task was not able to run at the appropriate time.
Task could not be scheduled because it was already running or pending.
Failure to run tasks on schedule.
Tesla Air Suspension (TAS) has detected an initiated CPU reset triggered by error conditions.
Reset can be caused by clock errors, flash issues, software faults, checkstop events, or debug requests causing CPU restarts.
May result in disrupted operation. Review logs and components post-restart.
Tesla Air Suspension (TAS) has detected an internal software assertion failure.
Triggers when a specific software condition fails during runtime operations.
May result in system instability.
Tesla Air Suspension (TAS) has detected an unplanned processor reset caused by power loss.
Occurs during sudden or unexpected power losses affecting the system.
May result in disrupted operation. Review logs and components post-restart.
Warns if the processor has experienced a reset due to watchdog reset.
A watchdog (external or internal) was not serviced in time.
Suspension controls may not continually work as intended.
