A: No – P0560 is a generic "Malfunction" (unstable or out-of-range). P0562 and P0563 are specific to low or high voltage only. However, Renault often logs P0560 as the master fault even when P0562/P0563 are pending. 11. Final Technical Note For Renault technicians using the CLIP diagnostic tool, P0560 is often cross-referenced with a parameter measurement called "Permanent Feed Voltage Stability Index." A value below 80% confirms intermittent connection. Always graph the voltage over 2 minutes with key-on, engine-off – any drop below 10V during that period confirms the fault is physical (wiring/connector) rather than alternator-related. This information is intended for professional technicians and experienced DIYers. Always consult Renault’s official workshop manual for your specific model and VIN before carrying out electrical repairs.
This diagnostic trouble code indicates that the Engine Control Unit (ECU) – often referred to as the Injection Computer or UCH (Vehicle Interface Unit) in Renault terminology – has detected an abnormal or unstable voltage supply on its permanent live feed. Specifically, the ECU's internal monitoring circuit has registered a voltage outside the expected operational range (typically below 10V or above 16V for more than a few seconds).
A: Most likely a bad connection at the engine bay fuse box or a corroded ground point. Voltage drop test will confirm.
A: Temporarily. The ECU’s non-volatile memory stores the fault. It will reappear within 5–10 ignition cycles unless the root cause is fixed.
