Check injection and anti pollution system fault on Renault - klavkarr

Measure the battery voltage with the engine off using a digital multimeter. A healthy battery should read .

The fault might be within the module itself, causing it to incorrectly detect a power issue. Symptoms of F00316

The most common cause. If the battery voltage drops too low during starting, it can trigger memory errors in the computer.

In Renault vehicles, DTC F00316 is a diagnostic trouble code that typically points to a Computer Power Supply Battery Voltage

DTC F00316 is a fault code that appears on Renault vehicles equipped with a diagnostic system. The code indicates a problem with the vehicle's electrical system, specifically with the "Computer" or "ECU" (Engine Control Unit).

If the alternator’s voltage regulator is failing or the drive belt is slipping, the alternator won't maintain the 13.8–14.4 volts required to feed the car's computer networks while the engine runs. Step-by-Step Diagnostic and Work Guide

When a Renault vehicle triggers this fault code, the vehicle’s electronic control units (ECUs)—such as the Anti-lock Braking System (ABS), Engine Control Module (ECM), or Instrument Cluster (IC)—detect an insufficient voltage supply. This under-voltage condition can severely disrupt multiplex communication systems across the CAN-bus network, leading to dashboard error messages like "Engine Failure Hazard" or "Check Braking System". Check injection and anti pollution system fault on

If the brake pedal’s rest position is slightly off (due to worn pedal bushings or previous repair work), the switches will not trigger at the correct moment, causing a plausibility error.

If you own a modern Renault (Clio, Megane, Captur, Kadjar, Scenic, or Talisman) or a vehicle under the Renault-Nissan alliance (like a Dacia or Nissan Qashqai), you might eventually encounter a frustrating moment: the check engine light illuminates, the car goes into limp mode, and your diagnostic tool reveals the cryptic code .

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

Multiple dashboard warning lights (often referred to as a "Christmas tree" effect). Symptoms of F00316 The most common cause

Clean terminals with a wire brush and tighten them securely. 2. Check the Battery Management System (BMS)

Clear the code and take a test drive. Does it return immediately? Only when braking? Only after using cruise control? This gives clues.

Inspect the primary for fraying or rust.

Sometimes, if the voltage drop was temporary (e.g., from an old battery), the code will not return. 4. Check Alternator Output
