3.7 4-Wheel Drive (Optional)
The 4-wheel drive mode is used to test brakes, anti-slip regulation (ASR) and automatic locking
differential (ASD) of 4-wheel drive vehicles.
The 4-wheel drive selection switch is required to activate the various modes.
0 = Standard (4-wheel drive mode off)
1 = ASR/ASD test
2 = “Rigid” 4-wheel drive
3 = “Visco” 4-wheel drive
Both the remote control Tele-BPS I and the pedal force meter are required to conduct the
4-wheel drive test.
The following paragraph describes the 4 wheel drive test for „rigid“ and for „Visco“-4 wheel drive
regulation. The tests for ASR and ASD are explained in the second paragraph.
3.7.1 Brake Test 4-Wheel Drive
A distinction is made between “rigid“ and “Visco“ 4-wheel drives. “Visco” 4-wheel drives are
subdivided again into “hard” and “soft” drives.
Before brake test is done connect cable of pedal force meter to remote control and attach pedal
force meter to shoe or brake pedal.
Attach reflex strips to vehicle tyres before the test if vehicles with
“rigid“ or hard “Visco” 4-wheel drive are tested.
With the help of a light barrier integrated into the brake tester
exactly one wheel revolution is recorded.
A = Reflex strips B = Light barrier
The motor control exactly records the RPM of the forward rotating rollers and transfers it to the
reverse rotating rollers. In this way power transmission to the second axle and torque on the
driveline are avoided.
Brakes are tested individually in the following order:
1 Front axle, left wheel
2 Front axle, right wheel
3 Rear axle, left wheel
4 Rear axle, right wheel
