Diagnosis / Trigger Conditions

These fault codes and the resulting BMW X5 seat massage inoperative condition typically occur after the vehicle undergoes programming or experiences a loss of power. The underlying cause is that the seat modules require re-initialization. This situation can affect either the driver's or passenger's seat, or both, if their respective modules are not properly configured.

Important Warnings

BMW notes that if a seat is not properly initialized, other seemingly unrelated functions, such as seat heating, may also be disabled. This highlights the importance of correct initialization for full seat functionality.

Repair Procedure Summary

To correct the BMW X5 seat massage inoperative issue, the seat modules must be re-initialized. This procedure is performed using the BMW diagnostic system, ISTA.

1. Access Initialization Procedure: Technicians should navigate to "SERVICE FUNCTIONS" within ISTA, then select "BODY," followed by "SEATS," and finally "SEAT ADJUSTMENT STANDARDIZATION." The correct ABL test plan for the specific affected seat must then be chosen.
2. Proper Seat Initialization: For successful initialization, the seats must be fully assembled with their leather covers. The initialization process has a time limit; if the seat leather/foam is not in place, the motor can move the seat frame past its intended stopping point, causing the seat to fail initialization. Additionally, if equipped, second-row headrests must be in the fully down position to prevent interference with the first-row seats during the initialization process. The initialization must be performed on all four seat modules if the vehicle is equipped with them.

This Service Information Bulletin SIB 52 09 25 also notes that these networked seats are described in more detail in Service Bulletin B52 23 19, which provides comprehensive information on all relevant seat bulletins.
