The Dynamic Drive system combats and reduces the vehicle's tendency to roll when cornering. The vehicle has increased vibration damping and its cornering capacity has been improved for optimal driving comfort. New limit values and zero settings for the front axle pressure sensor, rear axle pressure sensor and lateral acceleration sensor will be stored.
This function must be run after:
The Dynamic Drive system control unit has been replaced.
The Dynamic Drive system sensor has been replaced.
Work has been carried out on the Dynamic Drive hydraulic system.
Coding or programming of the Dynamic Drive control system.
The function includes the following steps:
Learning of the sensors' parameters.
Learning of the system's zero settings.
Dynamic Drive system self test.
If these values cannot be read correctly, the system may malfunction. It is therefore important that no faults occur in the system when the function is being run.
Note:
Start-up should never be performed when the vehicle is on a lift.
Test conditions:
Ignition on, engine off.
No faults in the system.
Oil temperature in the Dynamic Drive system's hydraulic system between 50°C and 70°C.
The vehicle must be on level ground.
All doors must be closed.
Accelerator pedal fully released.
There must be no objects underneath the vehicle or in any of the wheel arches.
There must be no persons near to the vehicle during start-up as the vehicle may rock during the procedure.
Procedure:
Start the function.
Start-up may only be performed on a fault-free system. The fault codes must therefore be cleared in the next step.
Start the engine and allow it to reach the operating temperature. The idling speed will be increased up to a preset value. Therefore, do not move the accelerator pedal during start-up.
Start-up takes approximately: 40 seconds to complete.
If the function fails, check the test conditions and repair any faults.
