stands for "System Voltage Malfunction." In plain English, your Renault’s Engine Control Unit (ECU) has detected that the voltage supplied to it is either too high, too low, or wildly inconsistent.

While P0560 can affect any vehicle, it is frequently seen in Renault models like the . P0560 - CaRPM

Driving with a P0560 code is risky. If the voltage is too low, the ECU may shut off the fuel pump or ignition coils, causing the engine to die while driving (dangerous in traffic). If the voltage is too high (overcharging), you risk frying your ECU, BSI, ABS pump, and headlights – a repair bill exceeding $2,000.

Why does this code appear? The causes range from simple wear and tear to complex wiring failures. Here are the most likely culprits for a Renault displaying P0560:

Unlike Japanese or German cars where P0560 is often a simple battery issue, Renaults have a unique electrical hierarchy. The ECU doesn't just read battery voltage; it communicates via the multiplexed network (CAN bus) with the BSI (Built-in Systems Interface – the smart fuse box/body computer). A voltage issue in the BSI can throw a P0560 even if the battery is perfect.

While the car may still run, prolonged driving is not recommended as undercharging can leave you stranded, and overcharging can damage sensitive electronics. Common Symptoms
