This 2-page BMW technical measure (53321250-02) addresses fault code E71430 'Rear seat temperature signal invalid' appearing in the IHKA system after replacing the FKA control unit. It explains that the issue is caused by software incompatibility with the improved FKA part number 61 31 9 290 750, which no longer integrates a temperature sensor. The document advises technicians to ignore the fault code if all FKA functions are normal, noting that the issue is resolved in ISTA D 2.36.0.
WHAT IS INSIDE THIS DOCUMENT (CIRCUITS, PINOUTS & SECTIONS):
