AL is automatically considering all WE identifiers received and extracts, based on statistical evaluation, IDs belonging to the WEs mounted on the vehicle. If new IDs are detected their recurrence will be tracked by AL. When AL is in progress, tire pressure monitoring is running in parallel with the old set of identifiers known from the last run of AL.
This DTC indicates that A failure of Auto-learning happens when less than WE sensors were learned.
