| Checking | ||
1 | Carry out preconditions and tests for vehicle level measurement | ||
2 | Clean measuring points | This prevents any measuring errors. | |
3 | Mount measuring sensor (086a) on spring control arm (17) and read off the vehicle level on the inclinometer (86) | Vehicles without code (P99) Special model "AMG Black Series": Mount measuring sensor (086a) between the cast in humps (arrows). | |
The connecting cable (086b) of the measuring sensor (086a) must point towards the center of the vehicle otherwise a faulty measurement occurs. | |||
Measure vehicle level at | |||
Vehicle level - front axle | |||
4 | Mount measuring sensor (086a) on rear axle shaft (65) and read off vehicle level on inclinometer (86) | The connecting cable (086b) of the measuring sensor (086a) must point towards the center of the vehicle otherwise a faulty measurement occurs. | |
Measure vehicle level at | |||
Vehicle level - rear axle | |||
5 | Check the maximum permissible difference in vehicle level between the left and right side of the vehicle | Vehicles without code (487) Active Body Control (ABC): The specified test tolerance applies only when checking the vehicle level and not for the calibration. | |
Permissible difference in vehicle level at front axle between right and left sides of the vehicle | |||
Permissible difference in vehicle level at rear axle between right and left sides of the vehicle | |||
Vehicles without code (487) Active Body Control (ABC) and without code P99 Black Series: If the vehicle level at the front or rear axle is outside the tolerance, the vehicle level must be adjusted by changing the springs of spring rubber mounts. | |||
Vehicles with code (P99) Special model "AMG Black Series": If the vehicle level at the front or rear axle is outside the tolerance: | |||
Adjust suspension. | |||
6 | Use STAR DIAGNOSIS to calibrate vehicle level | Vehicles with code (487) Active Body Control (ABC): If the vehicle level is outside the test tolerance. | |
| Connect STAR DIAGNOSIS and read out fault memory | ||
Permissible difference in vehicle level at front axle between right and left sides of the vehicle | |||
Permissible difference in vehicle level at rear axle between right and left sides of the vehicle | |||
Possible causes and remedies when the vehicle level is not OK after calibration: Attachment of level sensor is misshapen. | |||
7 | Adjust headlamps | Only if the vehicle level has been calibrated. | |
| Check and correct the adjustment of the headlamps |
