Diagnostic conditions
- Vehicle speed higher than 120 km/h and then lower than 60 km/h
- Manual actuationNOTE:
- 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 state
- The instrument cluster expects the checkback concerning the new state of the spoiler after the speed exceeds or falls below the limit and after relevant activation. If a state change 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.
- The warning text is displayed, depending on the version of the instrument cluster after model year 2003.
NOTE:
On failure of the PSM control module, the spoiler extends as soon as the ignition is switched on.
