911 Turbo (996) Instrument cluster K20 90 90-29Fault code 9150 Spoiler control Diagnostic conditions • Vehicle speed higher than 120 km/h and then lower than 60 km/ h • Manual actuation 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 con- trolled 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 dis- play. ♦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 dis- play). 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. Possible cause of fault ♦Fuse D7 faulty ♦Relays faulty ♦Micro switch faulty ♦Short circuit to ground/open circuit in the wiring between instru- ment cluster and relay carrier or spoiler control ♦Spoiler drive faulty 9025 Fault code 9150 90-29 page 1 Printed in Germany – 18, 2002 9150xk20
