In modern Renaults, a stable voltage supply—usually with the engine off and 13.5V to 14.5V while running—is critical for the vehicle's myriad electronic modules. When P0560 is triggered, it signals that the ECU can no longer guarantee the accuracy of sensor data or the stability of its own operations. Common Symptoms
Locate your vehicle's fuse box diagram and check the main fuses and relays related to the ECU/PCM and the charging system.

If the charging voltage is unstable, replace the alternator. Ensure you install a high-quality replacement, as low-grade aftermarket alternators often fail to communicate correctly with Renault ECUs. In modern Renaults, a stable voltage supply—usually with
: In some cases, there are no noticeable symptoms other than the stored code. However, ignoring it can lead to ECU damage or complete no-start conditions.
The battery charge warning icon may stay lit while driving. If you plan on diagnosing this yourself, do
Renault vehicles with Start-Stop technology are highly sensitive to battery degradation. If the battery can no longer hold a proper charge, the system voltage drops dramatically during heavy electrical loads. 2. Failing Alternator or Voltage Regulator
: A corroded negative ground strap from the engine to the chassis. The resistance was 0.8 ohms instead of 0 ohms. Replaced the strap with a €12 part. Voltage stabilized at 14.2V. Code cleared and never returned.
The (Diagnostic Trouble Code) refers to a System Voltage Malfunction in Renault vehicles. This generic powertrain code is triggered when the Engine Control Unit (ECU) detects an electrical system voltage that is outside the normal operating range, typically below 12V (undercharging) or above 15.5V (overcharging).
