Mounting tips TPMS tool: Before installation, check whether the vehicle is already equipped with a direct tyre pressure monitoring system. During the disassembly of the RDKS sensor, no pressure must be applied to the tyre pressure sensor. If the sensor can still be used, the appropriate TPMS Service Kit must be determined.
