Japan-built crossovers sold outside North America carry the WMI JM7, which no Mazda platform lists. platform_from_vin finds no candidate for them, and the firmware fallback stops too, since only OCEANIA_EXPORT VINs continue to the EPS-swap path. A 2025 CX-5 with a JM7 VIN therefore never fingerprints, even though its chassis code KF and model year code S already match MAZDA_CX5_2022. Add JM7 as EXPORT_CROSSOVER, accept it on MAZDA_CX5_2022, and add the engine and transmission firmware read from that car. Its EPS, ABS and forward camera versions are already listed.

JM7 is the WMI on Japan-built crossovers sold outside North America. No platform listed it, so platform_from_vin found nothing and the fuzzy path stopped as well, and a 2025 Latin-American CX-5 read as unknown although three of its five ECUs were already in the table. JM7 carries the same chassis and year fields as JM3, so it sits beside JM3 on every crossover platform; the car's engine and transmission versions are added. From #18 (klebeer), widened from MAZDA_CX5_2022 alone.

Merged onto danger-unstable as fc4c015, widened from your version: JM7 sits beside JM3 on every crossover platform, since it carries the same chassis and year fields and a 2017-21 export CX-5 or an export CX-9 would otherwise still read as unknown. Your two firmware strings are in as written. VIN tests cover JM7 KF S, KF L and TC P. We will test on the car from a personal branch before it reaches develop. Thanks for the clean report. |

Adds the WMI
JM7and accepts it onMAZDA_CX5_2022, plus two firmware versions.JM7is the WMI Mazda uses for Japan-built crossovers sold outside North America. No platform lists it, soplatform_from_vinreturns no candidate, andmatch_fw_to_car_fuzzystops as well because onlyOCEANIA_EXPORTVINs continue to the EPS-swap fallback. The result is "unable to identify your car" on a car whose chassis code and model year code already match the platform.The car

The firmware versions were read by the device's own query and are listed above; three of them already being in the table is what identifies the platform.Assisted-by: Claude
