The Renault (often appearing in diagnostic reports as 060AF1 ) is a critical fault code that signals a "Safety Mode 1 Flag" within the vehicle's computer system. This status indicates that the engine control unit (ECU) has detected a major calculation failure or a hardware inconsistency and has restricted the car's performance to prevent physical damage. 🛠️ Common Causes
In many cases, DTC060af1 forces the ECU into a . In this mode, the engine management system restricts power output to protect the engine from potential damage. The vehicle may still run, but acceleration will feel sluggish and top speed will be limited.
This code often appears alongside others like DTC 061A61 (Signal Calculation Failure). Identifying these related codes can pinpoint if the issue is a sensor or an internal ECU fault.
Measure voltage at idle: 13.8–14.5V. Check battery terminals for corrosion. A weak battery (below 12.4V after resting) can trigger false ESP faults. Renault Dtc060af1
Clear the codes and cycle the ignition. If the code returns immediately, it is likely a hardware failure like the brake switch.
If power supply codes are present, replace the and clean the ECU fuses. Step 2: Audit Recent Service History (The Spark Plug Check) If the code appeared shortly after an engine tune-up: Remove the newly installed spark plugs.

The internal monitoring processor in the ECU may detect a calculation mismatch between different sensors, such as the accelerator and brake pedals.
In simpler terms, the Renault ECU has detected an internal malfunction within the ESP/ABS hydraulic control unit or its related power supply/communication circuits. The "AF1" suffix often indicates a specific type of internal electrical irregularity—commonly a voltage discrepancy or a relay fault inside the ABS pump motor circuit.
: A malfunctioning brake pedal sensor is a primary cause for this specific code. If the ECU cannot verify the brake is pressed, it triggers a safety flag and prevents the car from starting. In this mode, the engine management system restricts
Often paired with DTC 061A61, indicating the ECM is struggling to process sensor data correctly.
: The vehicle may enter a restricted performance state to protect critical components. Root Causes & Solutions
Corroded ground points (especially the main chassis ground near the ABS unit) or a weak battery/alternator can cause voltage drops. The ESP module requires stable 12–14.5V. Deviations as short as 100 milliseconds can log this fault.
: In rarer cases, this points to a genuine internal checksum error or calculation failure within the control module itself. Recommended Action Plan
DTC060AF1 is rarely a standalone failure. It is almost always accompanied by secondary codes that provide clues to the true source of the problem.
