| EPB (Electronic parking brake and handbrake) on brake dynamometer |
| –
| Drive rear wheels of vehicle onto test rollers. |
| Do not switch off the ignition. |
| –
| The „test mode“ (TÜV mode) is activated as soon as the rollers reach a speed between 3 km/h and 9 km/h. |
| When the test mode is activated, the instrument cluster display will show „Parking brake under diagnosis“, and/or |
| The message „Parking brake“ will flash in the instrument cluster. |
| The EPB will now function as follows: |
| The full brake force is not applied at once, but step by step each time the parking brake switch is pulled. |
| After operating the switch a few times the brake force attained is sufficient for the measuring procedure. |
| Observe the display of the brake test rollers. |
| The brake is released by pressing the switch once. |
| Requirements for „test mode“: |
| –
| Front wheels, speed = 0 km/ h |
| –
| Rear wheels, min. speed = 3 km/ h, max. speed = 9 km/h |
| When the test mode is activated, the instrument cluster display will show „Parking brake under diagnosis“, and/or |
| The message „Parking brake“ will flash in the instrument cluster. |
WARNING | When testing models with four-wheel drive you must use brake test rollers with synchronised wheel speeds. |
