MRS 3

The MRS3 system was launched with the arrival of the 2-stage driver's airbag in March 1999. Another innovation on the MRS3 was its connection with the K-bus. The previous MRS systems had been hooked up to the diagnostic bus. The exception in that regard was the E36/7 (Z3). Since the Z3 has no K-bus, the MRS3 on the Z3 remained connected to the diagnostic bus.
