我地團隊一直進行 Tesla 維修方面既研究，不停喺 Tesla 官方提供既文檔及工具中發掘秘寶，最近我地喺 Toolbox 中發現咗一啲有趣既資料，十分值得同大家分享。
咩係 Toolbox?
Toolbox 係官方既維修工具，即係大家所謂既維修電腦。舊時既 Toolbox 2 係需要喺 Windows 上安裝一個程式，再透過特定線材連接部車既診斷接頭 Diagnostic Port，進行檢查及維修。
之後 Tesla 推出咗網上版本既 Toolbox 3，將部車駁落電腦後就可以直接喺瀏覽器進行診斷。好處係 Tesla 可以知道每個帳號既操作，同埋唔需要定期進行 Toolbox 軟件更新。
呢啲工具唔係原廠先用得架咩？
Tesla 近年陸續開放畀原廠以外進行維修，而 Toolbox 權限亦可以訂閱形式使用，收費為 165USD/day 或 500USD/month 或 3000USD/year。當然，我地用到既 Toolbox 同廠自己用既權限上有好大分別。我地可以進行到既維修相對有限。
我地發現到既細微硬件改進
喺 Toolbox 入面其實有好多野睇，加上我地一番 Javascript + JSON 既拆解，我地發現咗好多冷知識，亦對部車既了解更深入。其中我地覺得最有趣既就係 Vehicle Configuration。淨係睇呢幾千行代碼已經夠睇一兩星期。
小知識 1 – 新 Model S 及 Model X 代稱
2021 年 Tesla 推出改款既 Model S/X，新一代既系列被內部稱為 Palladium。而新 Model S 及 Model X 各自有自己既代號：
Model S – Lychee
Model X – Tamarind
小知識 2 – 部份 Model 3 冇 Pocket Light
Tesla 曾經短暫地喺 2020 年取消 Pocket Light 呢項配置，即係四隻門照住個儲物空間嗰盞燈，後來 21 年改款又加返呢個配置。

}小知識 3 – 上海製 Model 3/Y 轉用新座椅供應商
Tesla 喺 2020 年棄用自家座椅生產線、轉用座椅供應商 “延锋”，最有趣既係有部份車左右凳係用唔同既凳，@greentheonly 都有講過。有車主反映舊凳好坐啲，但係見人見致啦。

}小知識 4 – PWS 喇叭出咗 v2
大家平時倒車聽到既嗚嗚聲，其實就係由一隻外置喇叭 (Pedesitrian Warning Sound Speaker) 發出。文檔中可見，呢隻喇叭出咗 v2，而且呢個 option 係上年都仲未有既，所以推段 2023 年款既車應該換咗新喇叭。目前網絡上無人討論過，所以暫時未知有咩分別。

"value": 2
}]
},
"description": "Pedestrian warning sound configuration",
"products": ["Model3", "ModelY", "Tamarind", "Lychee"]
}小知識 5 – 美加尾燈同其他地方唔同
早期美加既 Tesla (2021 年之前) 尾燈都採用紅色指揮燈，迫力同指揮燈共用，而其他國家就用返黃燈。後期全球統一用哂同一款尾燈，用返黃色指揮燈。

}
小知識 6 – 中國獨家 Model 3 原廠後加電尾門
中國 Tesla 喺 2022 年初獨家為 2018-2020 年 Model 3 推出既原廠電尾門加裝服務，原來係同一間河北既公司 “HUADE” 合作。

}以上只係我地重點分享既一小部份，仲有好多例如係冷氣系統、剎車系統等既硬件型號資料。實際上可以設定既 configuration 多達百幾個！
大家對於架車既 Configuration 有咩想知？歡迎留言交流吓！
