Unclip the wiring harness plugs and check for blue-green corrosion on the pins.
The most frequent culprit is a decaying 12V lead-acid or AGM battery. When a battery suffers from high internal resistance or can no longer hold a full charge, its voltage drops drastically during high-load periods—such as starting the car or activating heavy electrical items like the electric power steering. 2. Corrosion on Battery Terminals or Ground Points
Components staying awake after the ignition is off can drain the battery, leading to a low voltage state upon the next startup attempt. 3. Recommended Diagnostic Procedure To resolve DTC F00316, follow these steps in order: Battery Load Test: renault dtc f00316
The Renault diagnostic trouble code (DTC) ) primarily indicates a low supply voltage to a specific electronic control unit, often the Battery Voltage/Feed Voltage

While the code tells you that voltage is low, it does not automatically mean a module is dead. The issue is almost always a breakdown in the infrastructure that delivers power: Potential Cause Description
When this code is present, you may notice several secondary warnings or performance issues: With F00316 active
The Protection and Switching Unit (known in Renault terminology as the ) sits in the engine bay next to the battery. Blocked scuttle panel drains (the plastic troughs beneath the windshield wipers) will overflow directly into the engine bay or the interior passenger footwell ( UCH module ). This causes water ingress, corrodes pins, and causes high resistance across power lines. Stop and Start function - user manual - Renault Group
is a specific manufacturer diagnostic trouble code that translates to "Battery Voltage / Computer Power Supply: Feed Voltage Too Low" . When this code triggers, it means a control module—most commonly the Anti-lock Braking System (ABS) module, the Dashboard Instrument Cluster, or the All-Wheel Drive (AWD) controller—is receiving an operating voltage below the minimum safe threshold.
Here is the story of a typical encounter with this elusive code. The Mystery of the Dim Dashboard
A: Absolutely. Stop-start relies on knowing battery voltage and alternator load. With F00316 active, the ECU disables stop-start to prevent stalling. Fixing the code will restore Eco mode.
