# Ford Fiesta MK5 MS-CAN: decoding the dashboard and radio bus > Documents the medium-speed CAN bus that links the 6000CD radio and the dashboard of a restyled (post-2006) Ford Fiesta MK5, worked out by tapping the bus at the radio's QuadLock connector with a Seeed CAN-BUS Shield on an Arduino Uno. The README describes 18 partly or fully decoded message IDs on the 125 kbit/s bus, with byte layouts and scaling formulas: radio text sent to the dashboard LCD over ISO-TP, station names, volume, CD track and steering-column mode and seek buttons, as well as broadcast clock, door, lock, reverse-gear, indicator, light, handbrake, airbag-lamp, pedal, RPM, speed, coolant, key-position, battery and partial VIN data. An incomplete Kayak .kcd definition encodes only the clock and gas-pedal/RPM/speed messages. - Type: Case study - Targets: Protocol - Category: Independent reconstruction cases - Relationship: Independent reconstruction project - Sources reviewed: 2026-10-27 - Added to the catalog: 2026-11-03 - Original resource: - Primary source: - Catalog page: - Record JSON: - Chinese version: [简体中文](https://awesomerea.org/zh/resources/ford-fiesta-mk5-ms-can-case/index.md) ## Requirements & limits - Documentation-only project with 25 commits from 2020-08-22 to the reviewed master commit of 2020-09-30, and no releases or tags. It applies to a Fiesta MK5 built after 2006 (the restyled model) with the 2-DIN 6000CD radio; the README notes that the steering-column volume buttons do not appear on MS-CAN, and the decoding of some IDs is partial. - No Ford software or files are needed; reading the bus requires a CAN interface on the CANH and CANL lines at the radio's QuadLock connector, which the README says needs no 120-ohm terminator. The author used a Seeed CAN-BUS Shield V2.0 on an Arduino Uno R3, but the repository holds only the README, the Kayak .kcd file, a connector pinout image and dashboard indicator icons, with no capture logs, sniffer code or Arduino sketch. - Message layouts and formulas such as volume, track time, speed, coolant temperature and battery voltage are author-reported from the author's own car, and the ISO-TP reading of the LCD text messages is credited to a Reddit commenter. The README documents decoding of observed traffic and gives no procedure for sending frames to the car. - The repository has no license file and GitHub detects none. ## Primary sources 1. 2. 3. 4. ## More in Protocols - [uniden-r8-ble: reconstructing the Uniden R8 radar detector's BLE telemetry](https://awesomerea.org/resources/uniden-r8-ble-telemetry-case/index.md) · Case study - [opendash: reconstructing the Scanmatik SM3 J2534 adapter protocol](https://awesomerea.org/resources/opendash-scanmatik-sm3-protocol-case/index.md) · Case study - [OWL: an open Apple Wireless Direct Link implementation](https://awesomerea.org/resources/owl-awdl-open-implementation-case/index.md) · Case study - [QuestPad: a USB gamepad from the Quest Touch radio protocol](https://awesomerea.org/resources/questpad-case/index.md) · Case study - [Stadiacast: reconstructing the Stadia Controller's Wi-Fi service](https://awesomerea.org/resources/stadiacast-case/index.md) · Case study - [os-xgs-npu: reconstructing Sophos XGS coprocessor interfaces](https://awesomerea.org/resources/os-xgs-npu-case/index.md) · Case study ## About this entry The description was reviewed against primary sources.
