Description
The Passive Management Unit (PMU) is a crucial component of modern vehicle security and convenience systems, responsible for managing passive keyless entry, engine start authorization, and other automated functions. The PMU communicates wirelessly with the vehicle’s key fob, detecting its presence and verifying authentication without requiring manual key operation. When the key fob is within the designated range, the PMU automatically unlocks the doors and allows push-button engine start. It also integrates with the vehicle’s electronic control systems via a secure communication protocol, ensuring protection against unauthorized access. The PMU enhances user convenience while maintaining robust security features, making it an essential part of advanced vehicle access and immobilization systems.
