Turn the ignition off, wait 30 seconds, then press down firmly on the brake pedal. Verify that the blinking gear indicator has stabilized. Start the engine to ensure smooth operation.
First, check if your brake lights work. A malfunctioning brake switch can cause the computer to believe the brake is constantly depressed, triggering safety mode. Replacing this switch is a simple and cheap fix.
Spray electrical contact cleaner into the main fuse box relays, paying special attention to the Main Power Relay (). Step 2: Track Down Cascading Codes
If you are unsure or lack the tools to perform the diagnostic steps described in this article, do not hesitate to consult a Renault specialist. Proper diagnosis saves time, money, and frustration in the long run. Renault Dtc060af1
: This base code points directly to an internal monitoring fault within the control module's processors (usually an internal PCM/ECM torque monitoring error or signal calculation mismatch).
In the most severe cases — especially those involving an incorrect ECU swap or a complete processor failure — the engine may . This was exactly the situation reported for a Renault Kwid after an engine swap: the vehicle cranked but did not start, and DTC060af1 was one of only two codes present.
In many Renault models, such as the Kwid, this code is frequently triggered by a faulty brake pedal switch Turn the ignition off, wait 30 seconds, then
is a manufacturer-specific hex-based diagnostic trouble code that signifies the Engine Control Unit (ECU/Computer) has entered Safety Mode 1 due to an internal calculation or software-hardware synchronization failure . When this fault triggers, the vehicle's engine management system restricts performance to prevent catastrophic damage, often trapping the vehicle in a "limp home" mode or preventing it from starting entirely.
| Test | Good result | Replace if | |------|-------------|-------------| | (engine off, 4h later) | >12.4V | <12.2V | | Cranking voltage (during start) | >9.6V | <9.0V | | Load test (drop to 9.5V for 10 sec) | recovers quickly | fails | | AGM/EFB type correct | Yes | Standard flooded battery installed |
A simple but effective diagnostic step is to and discharge the system to clear residual voltage from all ECUs. The recommended procedure: First, check if your brake lights work
Contact an authorized Renault dealer or a specialized ECU programming service to check if a is available for your ECU. This is often the cheapest solution when the problem is a software bug rather than hardware failure.
Diagnosing and repairing DTC060AF1 involves several steps:
A basic OBD2 scanner will read generic codes like P060A, but it (the “F1” suffix) or the companion codes stored in Renault’s proprietary modules. For a complete picture, you need a Renault-specific diagnostic tool , ideally the original CLIP system used by Renault dealers. This tool can access all modules and display the live data streams needed for accurate diagnosis.
