If a 81 2A F1 81 will trigger a bus init, then TPMS is available with the ELM . When I tried 83 F0 2A C1 D9 8F several years ago, there was no response. Note that the 2nd sequence uses the Mongoose id of F0, while the ELM is at F1. So maybe a 83 F1 2A C1 D9 8F would work. All of the F0 device addresses in my TPMS documentation need to be changed to F1 for the ELM.
