: A failed system main relay or a blown fuse in the ECU power circuit.
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). Understanding DTC P0560 in Renault Vehicles
For Renault models, this code is often accompanied by other voltage-related codes such as:
The ECM sets P0560 when:
: The Check Engine Light (CEL) or a red battery icon may illuminate on the dashboard.
Renaults utilize fusible links (large fuses) on the positive battery terminal. If one of these high-amperage fuses is blown or making poor contact, the ECU may lose its main power feed.
