The specific phrase "Consistent multiplex signals" usually implies that the signals being received by a control unit are contradictory, corrupted, or missing expected data frames from another module on the network.
This fault code indicates a communication error on the vehicle's Controller Area Network (CAN) bus. The "multiplexed network" is the wiring system that allows the various computers (ECUs) in the car—such as the engine control unit, ABS module, and dashboard—to talk to each other.
Faulty Brake Pedal Switch: This is the most frequent culprit. If the switch fails to send a signal when the pedal is pressed, the multiplex system detects a discrepancy.Wiring Harness Issues: Damaged, frayed, or corroded wires in the CAN bus network or between the brake switch and the ABS module.ABS Module Failure: A hardware or software glitch within the ABS unit itself can prevent it from broadcasting necessary data.Battery and Voltage Issues: Low battery voltage or a failing alternator can cause electronic modules to communicate erratically.Corroded Connectors: Moisture in the engine bay or near the chassis can lead to poor electrical contact in the multi-pin connectors.

The Renault DF1070 is a diagnostic trouble code (DTC) or fault code specific to Renault and Dacia vehicles. It relates to the Multiplexed Network . Faulty Brake Pedal Switch: This is the most frequent culprit
Historically, the DF1070 emerged from Renault’s ambitious "Project RS" under the direction of François Castaing and Bernard Dudot. While rivals like Ferrari, Ford, and Cosworth were perfecting the high-revving, 3.0-liter naturally aspirated V8 and V12 engines, Renault chose a path of calculated risk. The FIA’s 1977 regulations allowed for 1.5-liter forced induction engines, but the technical challenges—namely turbo lag, extreme heat management, and catastrophic failure rates—were considered insurmountable by most constructors. The DF1070 was Renault’s answer to this challenge. Its architecture was deceptively simple: a 90-degree V6 with two Garrett turbochargers and a pioneering Bosch fuel injection system. Yet, this simplicity masked a radical philosophy: power derived from air density, not just displacement.
To resolve the DF1070 error, a systematic approach is required: It relates to the Multiplexed Network
The legacy of the DF1070 is paradoxical. It is neither the most successful Renault F1 engine (a title held by the RS series of the 1990s or the V8s of the 2010s) nor the longest-lived. By 1981, it had been superseded by the more powerful and reliable EF series engines. However, its conceptual impact is immeasurable. The DF1070 validated the turbocharger as a viable performance tool, leading to the "turbo era" of the mid-1980s where engines like the BMW M12/13 produced over 1,400 bhp in qualifying trim. Moreover, the lessons learned from its fragile construction—specifically regarding heat dissipation, electronic engine management, and turbo lag reduction—directly informed modern engine design. Today, when Formula 1 uses 1.6-liter V6 turbo hybrids, the lineage is unmistakable. The DF1070 was the first step on a road that led to smaller, more efficient, and thermally intense power units.
Several factors can lead to the "missing braking information" signal:
