Level adjustment to make the height level sensors operational is required if the following work has been carried out on the vehicle:
Height level sensor replacement.
Control unit replacement.
Cable harness replacement.
When adjusting the level, the height is measured with a tape measure which is hooked to the centre of the rim flange at the bottom and measured up to the fender's edge.
Test conditions:
Before level adjustment is performed the engine must be turned on and off so that the air suspension is adjusted.
Any stresses in the chassis are released by rolling the vehicle back and forth for a short time.
Battery voltage above 12V.
Ignition on.
The vehicle must be standing on level ground.
The vehicle's current load must not be changed. Doors may not be opened and the engine may not be started. This may lead to incorrect settings in the chassis.
Tape measure to measure the height.
Procedure:
Start the function.
Follow the instructions in the program.
The function is complete.
