Even more bizarre: a handful of DF037s ended up in (offshore powerboat racing) and one even appeared in a French hillclimb special in the early 1990s, where it shattered records by 6 seconds on its first run.
The Renault fault code generally refers to an immobilizer system malfunction or a stop contactor circuit issue, depending on the specific control module (ECU) being scanned.

A malfunction of the EGR position sensor or exhaust pressure sensor.
On models like the Scenic 2 and 3, a brake switch coherence issue will trigger a "Check Parking Brake" warning message because the EPB does not know when to automatically release. Even more bizarre: a handful of DF037s ended
If a brake circuit error is suspected, crawl under the driver-side dashboard to locate the switch mounted above the brake pedal.
The ECU is the car's brain, and if it develops a problem, it may fail to communicate with the immobilizer system or the key. Issues can include internal component failure, software glitches, or water ingress leading to corrosion on the circuit board. Immobilizer modules themselves can also fail, though less frequently. or engine type
The engine turns over but refuses to start.
Because the brake switch acts as a primary safety cutoff for speed regulators, a coherence fault immediately disables the cruise control function. Common Root Causes
In many Renault models, especially the Scénic II and Grand Scénic, DF037 signifies a "Loss of ABS multiplexed transmission". This means the ABS computer is failing to send vital data (like individual wheel speeds and braking pressure) over the vehicle's Controller Area Network (CAN) bus to the main computer and other systems like the transmission and parking brake. This failure causes a cascading system failure, leading to multiple symptoms.
Because Renault uses different electronic control systems across its models, the exact meaning of DF037 can vary depending on the vehicle and the module being scanned. 1. Immobilizer System Malfunction In many Renault models, such as the Grand Scenic , DF037 indicates a failure in the engine immobilizer.
