⚙️ Rear SAM (Signal Acquisition Module) Function:
The Rear SAM is a critical body control and power distribution module that manages and monitors multiple rear-vehicle electrical systems, including:

• Rear exterior lighting (tail lights, brake lights, turn signals)
• Trunk release, trunk lighting, and rear accessories
• Rear fuse and relay power distribution
• CAN-BUS communication with other control modules
• Diagnostic monitoring and fault reporting

A faulty Rear SAM can cause intermittent lighting issues, trunk malfunctions, warning messages, or electrical communication errors.


🔧 Installation & Programming Notes:
• OEM direct replacement unit
• Physically plug-and-play, but SCN coding or programming may be required depending on vehicle configuration
• Dealer or professional diagnostic programming recommended
• Always disconnect the battery before installation

⚠️ This module does not reset VIN or mileage. Coding requirements vary by vehicle.


🔍 Physical & Cosmetic Condition:
• No cracks or structural damage to housing
• Fuse and relay sockets intact
• Connector pins straight and corrosion-free
• Clean OEM unit ready for installation


🎯 Ideal For:
• Replacing a faulty or water-damaged Rear SAM

• Restoring proper CAN-BUS communication
• OEM-correct electrical repairs without aftermarket risks


⚠️ Important Buyer Notes:
• This is a used OEM electronic module
