An implantable medical device communication system communicates information between an implantable medical device and at least one slave device by way of a two-wire bus. A lead wire 10 is attached to the lead side portion 8 containing no metal sulfide solid lubricant. The method allows reducing the number of spurious releases of the brake stand-by function, which a sportive driving style brings about. Preferably, the regulating system comprises a rotary motor, which drives the support assembly.
