High-Performance Engine Control Module (ECM) Connectors for Reliable Connectivity

Designing engine control modules for vehicle drivetrains requires sophisticated interconnect solutions, especially with the growing incorporation of electrification and advanced driver assist systems (ADAS). ECM connectors from Molex are engineered to meet these challenges by providing reliable, high-performance connectivity. The connectors optimize space efficiency, minimize signal loss and ensure dependability in high-temperature, high-vibration applications. These versatile and compact solutions enable real-time integration between the ECM and multiple vehicle systems, improving system operation and enhancing vehicle efficiency.

Designing Engine Control Modules


Modern vehicles require increasingly complex electronics to manage a large number of devices and control units. Electrified drivetrains and ADAS capabilities drive demand for low-latency, real-time data transmission, while space constraints and harsh automotive environments require connectivity solutions to be both compact and rugged. 
 
Integrating the safety and drivetrain systems in modern vehicles with the ECM requires compact, versatile and customizable interconnect solutions optimized for long-term reliability in automotive applications. Optimizing this integration improves system operation and enhances the driving experience. Robust ECM connectors help enhance vehicle efficiency, reduce maintenance costs and support ADAS innovations by delivering exceptional performance and reliability. 
 
Molex automotive connectors deliver versatile, reliable and high-density connectivity to integrate the ECM with a range of sensors and drivetrain systems. Designed for durability, these connectors feature robust housings, advanced seal designs and positive locks to protect against high temperatures, water and dust ingress, and vibration. High-performance data connectors deliver speeds up to 28Gbps/20 GHz, with electromagnetic interference (EMI) shielding to minimize signal loss. Hybrid connectors carry high current in compact, lightweight package sizes, maximizing space efficiency and functionality.


ECM I/O Connectors


Optimizing the performance of the ECM requires I/O connectors that are compact, versatile and robust. Molex automotive I/O connectors offer high-density solutions specifically ruggedized for automotive applications. These connectors have advanced features that deliver consistent performance and reliable signal integrity. Modular designs with customizable and hybrid power/signal options, simplify integration into evolving vehicle architectures, support electric and hybrid vehicles, and help enable ADAS functionality.
