4.4 Electromechanical parking brake on
brake test equipment
Test sequence:
– Drive rear wheels of vehicle onto test rollers; do not switch off
ignition.
– The “test mode” (TÜV mode) is activated as soon as the rollers
reach a speed between 4 km/h and 9 km/h.
– The instrument cluster will then display a crossed-out, yellow
symbol for the electromechanical parking brake ⇒ Owner's
Manual; Instruments and warning/indicator lamps .
The electromechanical parking brake 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 operated. After operating the
switch three times the brake force attained is sufficient for the
measuring procedure.
The brake is released by pressing the switch once.
Requirements for “test mode”:
– Ignition on
– Front wheels, speed = 0 km/h
– Rear wheels, min. speed = 4 km/h, max. speed = 9 km/h.
WARNING
When testing models with four-wheel drive you must use brake
test rollers with synchronised wheel speeds.
