Component Location





General Description

Auto Learning
AL(Auto Learning) starts every time, the vehicle was parked long enough to change or permute wheels(19min), and is traveling again at a speed that ensures that the WE sensors are transmitting. 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.
