Although we do not notice it, there is a huge network of electrical circuits in the closed sections of the vehicle. Same like the arms of an octopus in different parts of the vehicle wiring from the ECU and the sensors regularly reaches the sensors in the sensors to work correctly, the battery voltage should reach an electrical current to 5V and some car parts.
Keeping the electricity from the car parts and sensors to the desired voltage, grounding, demand and cut down on re-commissioning for the electrical circuit and turn off the power electronic switches that turn of this circuit (relays) are.
When the DF015 fault code is received in Renault vehicles, it means that there is a problem in the vehicle’s electrical system, which is complex but has a layout in itself.
Possible problems with the vehicle with the Renault fault code DF015:
- Failure of any electrical circuit, sensor, relay in the vehicle means that the function related to that part cannot be performed.
- Accordingly, some warning lights are lit on the instrument panel, warning messages appear on the message screen.
- There may be problems such as the parking sensor not working, the signal and headlights not working.
- When the DF015 Renault fault code is received, problems such as the vehicle not working, shaking, stopping, and not accelerating may occur.
What is the DF015 Renault fault code ?
The optical sensor circuit is in the form of a right side light circuit, and in some fault detection devices, the DF015 fault code is interpreted as “Main relay control circuit”.
Why am I getting the Renault fault code DF015 ?
- There is an electrical fault in your vehicle that causes a short circuit, and this fault causes the main relay to turn off the system.
- The so-called relay is an electronic switch. There are many relays and a main relay in the vehicle, and when there is a problem, the main relay turns off the power. Due to this, some systems do not work in the vehicle.
- There is also a possibility that there is a malfunction in the main relay, which may lead to the failure of the right side light circuit or the optical sensor circuit.
- Or vice versa, a problem in the right side light circuit or optical sensor circuit can also cause the main relay to turn itself off.
- Headlight relays in the vehicle are parts that prevent a bulb that consumes too much current from drawing too much power and damaging the installation, or a poorly lit bulb from flickering, intermittent burning, in a sense, balancing the electricity going to the bulbs.
- The cause of malfunctions related to relays may be battery-related problems.
- As a reason for experiencing such problems in the vehicle, it is usually indicated that water leaks into the hood or that water escapes from the electronics failure due to water when cleaning the vehicle.
- Water and moisture are the enemies of electrical components and are the main perpetrators of corrosion and short circuits that occur over time.
- The arrival of the vehicle’s electronic components, beautiful tampering and sloppy repair attempts can invite malfunctions that cause the DF015 fault code.
DF015 Renault fault code solution
- First of all, it should be checked whether there is a problem with the battery. The voltage of the battery is measured. If the voltage is good, the connections are checked.
- If the battery is low, it is checked whether there is a problem with the charging system.
- Since the fault code DF015 is commonly due to the fault of the main relay, the main relay and the fuse are checked.
- If there is no clicking sound when the starter is pressed, there is probably a relay failure in the vehicle.
- In addition to these, the right side light circuit and the optical sensor circuit are controlled. Information about the headlight relay What is the headlight relay for? you can get it from the titled article.
