|---|---|---|---|
|
ECU woke up repeatedly with ignition off. This hints at issues with vehicle-specific wake-up sources (e.g. door contact).
|
There was an excessive number of consecutive power cycles in which the ECU was woken up and went to sleep without that ignition was on.
|
System will be running with full assistant for driver brake request.
|
|
|
