B-CAN zpravy Doblo 263 — Low-speed CAN

B-CAN (29-bit, 50 kbaud, pins 1+9) nese data z body computeru, infotainmentu, pristrojove desky. Tyto zpravy lze monitorovat v rezimu ATSP7 + ATMA (monitor all).

Uzitecne B-CAN informace

Co lze sledovat na B-CAN

  • Stav dveri (otevrene/zavrene)
  • Stisknutí tlacitka na volantu
  • Audio kanal / hlasitost
  • Osvetleni interieru
  • Parkovaci senzory — vzdalenosti
  • Venkovni teplota (z dashboardu)

Jak monitorovat B-CAN

  • ATSP7 — prepnout na 29-bit CAN
  • ATMA — monitor all (zachytava vse)
  • ATCM + ATMR — filtr + monitor
  • Pozor: B-CAN je na pinech 1+9, ne 6+14!
  • Vetsina ELM327 adapteru podporuje jen piny 6+14
⚠ Pro pristup k B-CAN je casto potreba specialni adapter s pristupem k pinum 1 a 9 OBD konektoru. Standardni ELM327 Bluetooth/WiFi dongle typicky podporuje jen C-CAN (piny 6+14).

Novejsi Doblo modely maji SGW ktery blokuje zapis, aktuator testy a mazani DTC z third-party nastroju. Cteni standardnich OBD PIDu funguje. Neexistuje softwarove reseni — je potreba HW bypass modul.
Levne ELM327 klony
Mnoho levnych ELM327 klonu ma 120Ω odpor mezi CAN piny 6 a 14, ktery interferuje s komunikaci. Mel by byt odstranen. Doporuceni: pouzit originalni ELM327 v2.1+ nebo OBDLink SX/MX+.
Protokol auto-detect
Pokud si nejste jisti protokolem, pouzijte ATSP0 (auto) a pak 01 00. ELM327 se pokusi detekovat protokol automaticky. Potom ATDPN zobrazi cislo detekovaneho protokolu.
Mode 22 prefix
Pres ELM327 posilejte: 22 + DID. Napr. pro DID 2130 (otacky): 22 21 30. Odpoved zacina 62 21 30 + datove bajty.

Doporuceny software

  • MultiECUScan — nejlepsi Fiat-specificky diagnosticky nastroj
  • AlfaOBD — Android/Windows, siroka podpora FCA vozidel
  • FiatECUScan — starsi, ale stale funkcni pro Mk1
  • Torque Pro — Android, dobre pro vlastni PIDy
  • Car Scanner ELM OBD2 — jednoduche mobilni rozhrani

ECU varianty podle motorizace

  • 1.3 MultiJet — Marelli MJD6F3 / Marelli 6F3 EOBD (K-Line a CAN)
  • 1.6 MultiJet — Bosch EDC16C39 / EDC17C49 (CAN)
  • 1.9 JTD — Bosch EDC15 / EDC16 CF4
  • 1.4 Petrol — Delphi MT27E
  • Starsi Mk1 modely mohou pouzivat KWP2000 na K-Line (ATSP4/ATSP5)
STN-based adaptery (OBDLink)
OBDLink adaptery podporuji davkove dotazy: STPX H:18DA10F1, D:22 1002 195A 181F 1937, R:6 — cteni vice PIDu najednou, mnohem rychlejsi nez sekvencni dotazy.

FCA platforma — kompatibilita

Alfa Romeo, Fiat a Chrysler vozidla ve skupine FCA sdileji mnoho ECU platforem a PIDu. Data potvrzena na Fiat 500, Alfa Giulietta nebo Chrysler platformach velmi pravdepodobne funguji i na Doblo stejne generace.

Postup pripojeni krok za krokem

1. Fyzicke pripojeni

  • Pripojte ELM327 do OBD-II konektoru (pod volantem vlevo)
  • Zapnete zapalovani (klic do polohy MAR / ON, nebo start bez startovani motoru)
  • Pripojte se k ELM327 pres Bluetooth/WiFi/USB

2. Inicializace

  • Poslete ATZ pro reset
  • Poslete ATE0 ATL0 ATH1
  • Nastavte protokol: ATSP6 (Mk2) nebo ATSP5 (Mk1)
  • Otestujte: 01 00 — meli byste dostat odpoved

3. Cteni dat

  • Standard PIDs: 01 XX
  • Fiat extended: 10 03 (extended session) → 22 XX XX
  • DTC: 03 pro cteni, 04 pro mazani
  • VIN: 09 02
