The Renault fault code DTC060AF1 (often appearing alongside DTC061A61) typically indicates that the vehicle's computer has entered "Safety Mode 1". While it sounds like a critical engine failure, it is frequently a secondary symptom of a simpler electrical issue rather than a total computer breakdown. Diagnostic Meaning
Computer Safety Mode 1 Flag: This status code means the Engine Control Unit (ECU) has detected an inconsistency in safety-critical signals and has restricted vehicle performance (limp mode) or prevented the engine from starting to protect the hardware.
Common Context: On models like the Renault Kwid, this code often appears when the car refuses to start or the gear/brake lights blink continuously. Common Root Causes
Based on diagnostic reports from platforms like ThinkCar and technical insights from The Mechanic Ganesh, the most likely culprits are:
Faulty Brake Switch: 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.
Low Battery Voltage: Voltage levels below the required threshold (often reported as DTCF00316) can cause the ECU to "glitch" and throw safety mode flags.
Main Relay Issues: A short circuit to earth in the main relay control circuit (DTC065711) can prevent proper power delivery to the ECU, triggering safety mode.
Internal Electronic Failure: In rarer cases, this points to a genuine internal checksum error or calculation failure within the control module itself. Recommended Action Plan
Check the Brake Switch: Verify if your brake lights function correctly. Replacing a faulty brake switch often clears the DTC060AF1 and DTC061A61 codes immediately.
Test Battery Health: Ensure the battery is providing a steady 12V+. Low voltage is a frequent trigger for "Safety Mode" in Renault electronic systems.
Inspect Main Relays and Fuses: Check for corrosion or loose connections in the fuse box (UPC), especially the relays responsible for the injection system.
Perform a System Reset: You can attempt a basic reset of the infotainment and trip computer by holding the power button for 10 seconds, though this may not clear deep-seated ECM fault codes.

The vehicle may enter "Limp Mode" or a restricted performance "Safety Mode". Common Causes Brake Pedal Switch
: A malfunction in this sensor is a primary cause for Kwid and other AMT models. Blown Fuse
: Check the 7.5A brake switch fuse in the glove box or fuse panel. Software Corruptions : A calculation failure within the engine computer. Recommended Troubleshooting Steps Check Brake Lights
: If your brake lights do not illuminate when pressing the pedal, the brake switch is likely faulty. Inspect Fuses
: Verify the integrity of the brake circuit fuse (typically 7.5A). Diagnostic Scan : Use a dedicated tool like Renault Clip
or a compatible OBD2 scanner to clear the memory and see if the code returns after hardware checks. Professional Inspection
: If the brake switch and fuses are fine, the ECU may require a software update or professional repair due to an internal processing unit fault. or specific fuse locations for a particular Renault model like the Kwid or Duster?
The Renault DTC 060AF1 (also often paired with DTC 061A61) indicates an internal control module issue, specifically described as "Computer - Safety mode 1 flag". In practical terms, this code is frequently triggered by a malfunctioning brake switch or pedal sensor, which forces the vehicle's Engine Control Unit (ECU) into a protected "Limp Mode" or prevents the vehicle from starting, especially in AMT (Automated Manual Transmission) models. DTC 060AF1 Fault Report 1. Code Definition & Meaning DTC Description: Computer Safety Mode 1 Flag.
System Affected: Injection / Engine Control Module (ECM/ECU).
Condition: The ECU has detected an inconsistency in safety-critical signals (like brake and accelerator inputs), causing it to enter a restricted performance mode to protect the engine and transmission. 2. Primary Root Causes
Based on diagnostic field reports for Renault vehicles (notably the Kwid and similar AMT models):
Faulty Brake Switch: The most common culprit. If the ECU receives an invalid or inconsistent signal from the brake pedal switch, it cannot verify if the vehicle is safe to start or shift gears.
Pedal Position Sensor Issues: Inconsistency between the brake and accelerator pedal positions. The Renault fault code DTC060AF1 (often appearing alongside
Low Battery Voltage: Voltage irregularities can cause the ECU to flag internal "safety mode" errors as it loses stable communication with sensors.
Wiring/Connector Corrosion: Damaged wiring harnesses or corroded pins at the ECU or brake switch connector. 3. Common Symptoms
No Start Condition: The vehicle may refuse to crank, often showing a flashing symbol or "Check Electric System" message.
Limp Mode: Significantly reduced engine power and restricted gear shifts.
Warning Lights: The "Check Vehicle" or "Injection Fault" lights are typically illuminated on the dashboard.
Flashing "L" Symbol: On some service screens, a flashing "L" or transmission initialization error may appear. 4. Recommended Troubleshooting Steps
Renault diagnostic trouble code (DTC) is a manufacturer-specific code often described as " Computer Safety Mode 1 Flag
". It typically indicates that the vehicle's Engine Control Unit (ECU) has entered a restricted "limp mode" due to a safety-critical fault or data inconsistency. MFC Auction Key Meanings and Causes
While the code literally refers to an ECU safety flag, it is almost always triggered by an underlying component failure rather than a faulty computer itself. Common associations include:
The Renault diagnostic trouble code DTC 060AF1 is a technical fault code rather than a consumer product, so a standard "review" refers to its diagnostic meaning, common symptoms, and typical solutions. Diagnostic Overview
DTC 060AF1 is defined as "Computer - Safety Mode 1 Flag". It indicates that the vehicle's Engine Control Module (ECM) has entered a restricted operating state—often referred to as "limp mode"—to protect the engine or transmission from potential damage due to a detected irregularity. Common Root Causes
While the code itself represents a software "flag" for safety mode, it is frequently triggered by specific hardware failures in Renault vehicles, particularly the Renault Kwid (AMT):
Faulty Brake Switch: The most common trigger for this code. If the brake pedal switch malfunctions, the ECM cannot confirm the brake is pressed, which is a safety requirement for starting AMT (Automated Manual Transmission) vehicles.
Computer Signal Calculation Failure: Often paired with DTC 061A61, indicating the ECM is struggling to process sensor data correctly. Fix 2: Repair or Replace the ABS Control
Low Supply Voltage: Permanent low voltage to the computer can trigger safety flags as the system can no longer guarantee accurate sensor readings. Typical Symptoms
No-Start Condition: The car may refuse to crank or start, especially if the AMT system cannot verify the brake pedal position.
Limp Mode: Significant loss of power and restricted RPMs while driving.
Warning Lights: Often accompanied by "Check Vehicle" messages or the yellow spanner (service) icon on the dashboard.
Blinking Neutral Light: On AMT models, the "N" light may flash, indicating a transmission-related safety lockout. Recommended Solutions
Inspect/Replace the Brake Pedal Switch: Since this is a high-probability culprit, testing or replacing the switch often resolves the starting issue immediately.
Check Battery and Alternator: Ensure the battery is providing a steady voltage (typically above 12.6V when off and ~14V when running). Low voltage is a known trigger for computer safety flags.
Clear Memory and Re-test: Use a diagnostic tool like the Autel MaxiSys to clear the "Memory" status of the code and see if it returns as "Active".
Wiring Inspection: Check the wiring harness and connectors for corrosion, particularly around the battery and ECU.
