TPMS Option

Reading and writing TPMS wheel sensor IDs from/to the Baolong TPMS ECU is supported by OVMS in Tesla Model S cars using the Baolong system (vehicles produced up to around August 2014). You can easily tell if you have this Tesla Model S Baolong TPMS system as Tesla doesn’t support displaying tyre pressures in the instrument cluster. By contrast, the later Continental TPMS system does show the pressures in the instrument cluster.

OVMS directly supports the Baolong TPMS in Tesla Model S cars, without any extra hardware required. You simply need the usual OVT1 cable.

To read the current wheel sensor IDs from the Baolong TPMS ECU, ensure that the car is ON (simplest is to wake the car up and put in drive), and issue the ‘tpms read’ command in OVMS.

Similarly, to write wheel sensor IDs to the Baolong TPMS ECU, ensure that the car is ON, and issue the ‘tpms write’ command in OVMS.
