ACC, Calibrating During Vehicle Alignment

- Follow the information in the alignment equipment.

When must it be calibrated?

It must be calibrated if:

• The lock carrier was removed and installed,

• The adaptive cruise control sensor was removed and installed,

• If the toe and/or rear axle camber was adjusted during a vehicle alignment.

• The lock carrier was moved into the service position.

What test requirements must be fulfilled for calibration?

• Previously performed vehicle alignment or wheel run out compensation.

• Specified values for tire pressure and height are checked.

Observe the following work sequence!

Measuring Procedure






Space Requirements in Front of the Vehicle





- a - = 1145 mm +/- 5 mm

Distance - a - is the distance between the automatic cruise control sensor mirror and the ADC test fixture (VAS 6041) / setting device basic set (VAS 6430) measuring field

• If necessary, use precision spoiler adapter (V.A.G 1813/12) to equalize the height between the ACC test fixture (VAS 6041) / setting device basic set (VAS 6430) and the vehicle alignment platform.

Y Measuring block 6-2
Z Measuring block 6-3

Example:

Value 0.1 corresponds to 4 mm on the (VAS 6041/2) and/or the (VAS 6430)

The display on the vehicle diagnostic tester show a value of 0.6 in measured values block 6-2 and a value of -1.0 in measured values block 6-3.

These values lead to a measuring point - arrow - that consists of the following values:

- a - = 24 mm

- b - = 40 mm

Selection on the Vehicle Diagnosis Tester:

- Press the following buttons on the screen one after the other:

• Chassis

• Adaptive cruise control

• 01 - OBD-capable system

• Functions
