Nov 7, 2023 · Hi, My Eldiss Motorhome on a Ducato Chassis 2022 140 Multijet Euro 6 Engine displays a flashing glow plug light. A diagnostic scan ( Multiecuscan ) shows DTC P0683-13 Preheating control unit (feedback) Open circuit.

Jan 17, 2019 · Ducato 2,3 JTD my: 2006 No glowing at all, has P0380 and P0683 fault. As I see all live data about temperature is fine. Checked plugs, 0.9 Ohm all, checked at end of wire at glow relay too.

Sep 7, 2024 · The P0683 code indicates a communication failure between the Glow Plug Control Module and the PCM (Powertrain Control Module). This communication link is critical for controlling the operation of the glow plugs, which heat the engine cylinders for easier starting.

Code P0683 indicates that the Glow Plug Control Module to PCM Communication Circuit has lost communication. A fault has occurred that prohibits the powertrain control module (PCM) from communicating commands to the glow plug control module.

Mar 29, 2014 · If there is a spell of warm weather and the glow plugs aren't being used for cold starting, after 5 or 6 engine starts the flashing warning light is extinguished. A code P0683 will remain stored until it is cleared via the OBD port. However, if there is a faulty plug then when colder weather returns the problem will resurface.

Jan 30, 2010 · P0683 - Pre-Heater Module feedback. I can't see anything wrong with the wiring from the glow plug relay to the ecu so maybe a faulty relay. The P1304 though has me stumped.

Sep 17, 2024 · Il codice P0683 si attiva quando l’ECU rileva un’anomalia nel circuito del relè di preriscaldamento. Questo può essere causato da diversi fattori, tra cui: Relè delle candelette guasto: Il relè potrebbe non funzionare correttamente, impedendo alle candelette di ricevere corrente elettrica.

To fix P0683 code for communication problems between the glow plug control module and PCM, test resistance between their designated pins using breakout boxes for access. Check wiring for loose or damaged connections, ensuring proper continuity and absence of corrosion.

P0683 is a generic code for glow plug module encountering a communication circuit error, and can be detected by the PCM or the control modules for the transmission, ABS, instrument panel, body, turbo, anti-theft, cruise control, climate control, proximity alert, or traction control modules.
