Access the specific module flagging the code (ABS/ESP, PAS, or Instrument Cluster).
Because this code is related to the power supply, the cause is usually electrical rather than mechanical.
: Modern Renaults are highly sensitive to voltage drops. An aging or discharged battery (often 5+ years old) is the most frequent cause for F00316.
: Use a fuel injector cleaning kit or consider replacing faulty fuel injectors. renault dtc f00316 work

| Cause Category | Specific Issue | |----------------|----------------| | | Short to ground / short to battery / open circuit in solenoid wiring inside TCU | | Mechanical | Solenoid valve stuck due to metal debris or degraded transmission fluid | | Hydraulic | Low hydraulic pressure due to worn pump or fluid leak (affects solenoid operation) | | TCU Hardware | Failed driver chip (MOSFET) inside the TCU – common in early 6DCT250 units | | Battery/Charging | Low voltage (<11V) or unstable voltage causes solenoid driver misbehavior | | Water ingress | Corrosion in TCU connector (especially after pressure washing engine bay) | Access the specific module flagging the code (ABS/ESP,
This advanced test finds high resistance in a circuit. With the system under load (e.g., cranking the engine), you measure voltage across the positive and negative cables and their connections. A reading above 0.2-0.5 volts indicates a significant voltage drop and a bad connection.
This fault code is not always a direct component failure (like a failed sensor) but often points towards a malfunction in the communication or power supply within the vehicle’s electrical architecture. Based on diagnostic reports, the error often points to: DTC F00316: Computer Power Supply (Active/Memory)
In summary, the DTC F00316 is most often a sign that your Renault's electrical system is suffering from low voltage, caused by a failing battery, a loose connection, a faulty alternator, or damaged wiring. While it can affect different systems—from power steering to engine performance—the fix is often simpler and more cost-effective than you might expect. An aging or discharged battery (often 5+ years
When this code is active, you may notice several secondary warning messages on your dashboard because the car's computers (like the ABS or Instrument Cluster) are not receiving enough power to function correctly: "Braking System Fault" or "Braking Fault" "Battery Charging Fault" Dim lights or failure of low-power LED components
