There are several systems for measuring speed in vehicles, and systems that increase driving comfort work based on data from speed sensors.
Renault vehicles have a main speed sensor to measure the speed of the vehicle, and the data of this sensor is interpreted by the engine control unit and sent to the instrument panel for the driver to see. Thus, the driver learns how many km per hour the vehicle is traveling by looking at the dashboard.
Apart from this, there is also a transmission speed sensor. The transmission speed sensor determines the speed of the vehicle and sends it to the ECU (engine control unit) to calculate the gear ratio, determine the fuel/air ratio and set the ignition time.
Sensors on the wheels measure the rotation speeds on the wheels and provide data to systems such as ABS, ASR and ESP.
Systems such as adaptive cruise control, cruise control and speed regulator in Renault vehicles also need data from speed sensors.
The Renault fault code DF1012 tells us that the data of the different speed sensors do not match each other. The data of the Deceleration sensors cannot be expected to be exactly the same, but the differences between them should not exceed certain limits. If one of the sensors is not working or the data is very different, the ECU generates an error code.
Sometimes there may be other malfunctions underlying this problem.
Possible problems with the vehicle with the Renault fault code DF1012:
- The lights of ABS, ESP, ASR, Adaptive cruise control, cruise control and collision control system (systems may differ depending on the model of the Renault vehicle) may light up on the instrument panel of the vehicle, these systems may light up.
- The engine fault lamp or other warning lamp may light up.
Translating these descriptions of scanning devices our cruise control (CC) and Cruise Control (SL) of the sensors, the data do not match with each other, and this is reason Number 2 of the sensor feed voltage is insufficient (it doesn’t sound electric, cable, jutting relay sensor faulty or damaged)is.
Causes of the DF1012 Fault Code
- The common cause of this problem is that at least one of the sensors measuring the speed in the vehicle is broken or the cable is dislodged or dirty because it cannot read properly.
- Another common reason is that water escapes into the electrical circuits of the sensors in the car wash and short circuits.
- There will also be a data mismatch if the sensor is not installed on at least one of the wheels.
- Since the sensors work with electricity, battery-related problems or electrical leakage in the vehicle lead to the generation of error codes caused by the sensors.
DF1012 Renault Fault Code Solution
- For the solution of the problem, it can be started from the problem of rusting of the battery terminals, loosening of their connections, weakening of the battery, which seems to be the most irrelevant, but is commonly encountered. Because this is the simplest thing to control.
- If it is not known exactly where the fault originates in a vehicle, it is first started from the elements that cause simple and widespread problems to control it. Measuring the battery power and checking its connections is one of them.
- The fault signs on the instrument panel will give us a clue as to where the problem is.
- It must be confirmed that the speed sensors are clean, Jul-tioned and in working order, the speed sensors on the wheels are complete.
- If there is a sensor malfunction, it should be checked what is causing it, whether there is a relay malfunction.
- The DF1012 fault code in Renault vehicles is a problem that is easy to solve and has a low cost compared to other types of faults.
- However, if the electrical component of the vehicle is damaged, there is a possibility that such problems will recur.
