Product Overview
The Mercedes-Benz MR2 (Multi-Rear-Module) is an integrated rear control unit designed for Mercedes-Benz trucks, providing centralized management of rear lighting, trailer connectivity, and safety systems. This sophisticated electronic module enhances vehicle visibility, trailer communication, and rear-end safety while supporting advanced telematics and diagnostics for modern fleet operations.
Key Technical Features
Integrated Rear Lighting Control
- Centralized LED Lighting Management: Controls all rear lighting functions (brake, tail, turn, reverse, fog) with adaptive brightness adjustment
- Automatic Failure Detection: Monitors and reports individual bulb/LED failures in real time
- Lighting Sequences and Patterns: Supports dynamic turn signals and region-specific lighting behaviors
Trailer Connectivity and Communication
- Intelligent Trailer Recognition: Auto-detects trailer type and configures electrical interfaces accordingly
- ISO 7638 and 12098 Compliance: Ensures compatibility with standard trailer connectors and ABS/EBS systems
- Continuous Trailer Monitoring: Real-time monitoring of trailer lighting, braking, and electrical system status
Safety and Sensor Integration
- Rear Camera and Sensor Support: Provides power and data interfaces for up to two rear-view cameras and parking sensors
- Blind Spot Assist (BSA) Integration: Interfaces with radar sensors for enhanced rear and side safety coverage
- Reverse Assist System: Enables automated support during reversing maneuvers with visual/audible alerts
Diagnostics and Telematics
- CAN FD Communication: High-speed data exchange with vehicle’s central network for real-time status updates
