If you measured low voltage while the engine is running (or voltage spiking above 15V), the alternator is faulty.
If replacing the switch does not clear the code:
If you are ready to perform the work to clear DTC F00316, follow this diagnostic path: 1. Inspect the 12V Battery Health

This Diagnostic Trouble Code (DTC) indicates a general fault in the CAN (Controller Area Network) multiplexing system . Specifically, it usually signifies a loss of communication with one or more control modules on the network, or a physical fault in the wiring connecting them.
The "16" suffix in this code is a standard sub-type indicator for "Circuit Voltage Below Threshold". When your Renault's diagnostic system logs this, it means a module—frequently the or ABS/ESP system—is receiving less power than it needs to operate reliably. Common Symptoms If you measured low voltage while the engine
Ensure the main power feed to the ABS module is receiving full battery voltage. 4. Clear Codes and Re-test
Sometimes, low voltage affects the electronic parking brake system.

The vehicle may experience sudden power loss, or disable functions like the cruise control and speed limiter.
To properly fix F00316, you must understand how the Renault braking input system works. It is not as simple as older cars.
Remove the battery cover and locate the secondary red/black fuse box distributions near the positive terminal.
Use a wire brush to scrub away any white/green oxidation or powdery corrosion.
