Before using any tools, pop the hood for a manual check.
When P0560 is present, you will likely notice one or more of the following symptoms:
The Engine Control Unit (ECU) detects that the main supply voltage (typically +12V from the battery) has fallen below or risen above the acceptable operating threshold (usually <8V or >16V for more than a few seconds) on the permanent power feed.
Use a digital multimeter to test the battery with the engine turned off. dtc p0560 renault
Renault places fuse boxes (often the UCH or engine bay fuse unit) in areas exposed to moisture.
Open the engine bay fuse box (UPC). Look closely for signs of water damage, green corrosion on the fuses, or melted plastic. Pay special attention to the large maxi-fuses that supply main power to the cabin and ECU. Step 5: Read Live Data with a Scanner

Have an assistant start the engine while you watch the voltage display.
Ensure it is fully charged and holds a load. Clean the terminals and ensure connections are tight. Check the Alternator:

DTC P0560 on a Renault is a critical warning that your vehicle's electrical foundation is compromised. Because modern Renaults rely heavily on multiplexed wiring networks (CAN bus), neglecting a system voltage issue can cause a cascade of false sensor readings and component failures. By systematically testing the battery, cleaning ground connections, and verifying alternator output, you can quickly isolate the problem and restore your vehicle’s electrical health.
