Ensure clean 12V/5V reference lines; weak car batteries easily simulate false multiplex faults. How to Fix and Resolve DF357
The adaptive cruise control system relies on a radar sensor, usually located behind the front grille or bumper, to monitor the distance to the vehicle ahead. If this sensor malfunctions, it cannot provide valid data, leading to a DF357 code on the ABS side that is expecting that data.
The most common symptom is the cruise control system turning off or displaying "Check Cruise Control".

Look for a cracked, missing, or filthy magnetic ring on the CV joint. Fix: Replace the damaged ABS ring. 3. Check Sensor and Wiring
When the vehicle registers the DF357 fault, the ECU typically deploys safety protocols to protect the powertrain. Drivers may observe several distinct symptoms:
. When this code is triggered, it typically indicates a signal inconsistency or a circuit malfunction detected by the ABS control unit. 1. Common Symptoms Warning Lights Ensure clean 12V/5V reference lines; weak car batteries
In Renault’s specific diagnostic language, DF357 stands for:
Inspect ABS sensors and magnetic rings, particularly on the rear wheels, for dirt or damage. 3. Wiring Harness Issues (Short Circuit/Ground Fault)
This article provides a comprehensive guide to understanding, diagnosing, and fixing the Renault DF357 error, drawing from Drom.ru and Drive2 user experiences. What is the Renault DF357 Code? The most common symptom is the cruise control
Renault employs a proprietary diagnostic protocol where "DF" stands for Défaut Fonctionnel (Functional Fault). Unlike generic OBD-II codes (such as P0300 or P0100), Renault-specific DF codes provide a deeper level of granular data when scanned using dedicated diagnostic multiplexers like the tool or advanced multi-brand scanners.
You will see permanent warnings for "Check ABS," "Check ESP," or "Hill Start Assist Unavailable".
Read codes across all modules: Engine Injection, ABS/ESP, and UCH (Body Module).
If you have this code, do not immediately replace parts. Follow this diagnostic path:
