Diagnostic conditions

NOTE:

From a vehicle speed of 120 km/h, the spoiler is extended and retracts again when the speed falls below 60 km/h. This is controlled via the instrument cluster.
By means of microswitches which are attached to the spoiler control, the instrument cluster receives the checkback of faults concerning the spoiler status
The instrument cluster expects the checkback concerning the new status of the spoiler after the speed exceeds or falls below the limit and after relevant activation. If a change in status is not registered despite the control, the fault code 9150 is stored and the warning text Failure of spoiler control is emitted on the display.
Depending on the software version of the instrument cluster, only the warning text is displayed without the fault code 9150 being stored.
In GT2 vehicles, depending on the software version, the fault code 9150 spoiler control is stored (without warning text in display). This is a software problem and the fault entered should be ignored.

NOTE:

On failure of the PSM control module, the spoiler extends as soon as the ignition is switched on.
