Manufactured with industrial-grade durable circuit boards, waterproof sealed housing, and original-spec chip components, this rear SAM control module undergoes strict programming and performance calibration to match factory electrical parameters. Installed in the rear vehicle electrical compartment, it fully matches original plug interfaces, mounting positions, and system communication protocols. It perfectly fits Mercedes-Benz GL320, ML350, and R350 vehicles from 2006 to 2012 with factory rear SAM signal acquisition systems.
Upgraded to solve common failures of aging factory SAM modules, this unit features enhanced anti-interference circuit design and improved heat dissipation structure to resist high-temperature and vibration damage during long-term driving. Unlike original modules that easily cause signal delay, circuit failure, and functional disorder after aging, our replacement module maintains stable signal transmission and accurate electrical control. Pre-programmed and plug-and-play ready, it eliminates complicated coding steps for most vehicle models, greatly improving installation efficiency for DIY owners and professional repair shops.
Faulty rear SAM control modules trigger a range of common recurring electrical issues on Mercedes GL320, ML350, and R350. Typical problems include non-functional rear brake lights, turn signal failure, reverse light malfunction, intermittent rear electrical system blackout, dashboard electrical fault alerts, unstable trailer signal output, and abnormal battery power drainage. Many owners face repeated module failure and troublesome electrical troubleshooting due to OEM component durability defects; this upgraded module permanently resolves these widespread factory electrical faults.
Replacing the defective rear SAM control module clears common electrical system trouble codes caused by signal loss and module failure, including P0500 (Vehicle Speed Sensor Malfunction related to SAM signal error), B1000 (Control Module Internal Fault), B1402 (Rear Lighting Circuit Failure), and intermittent CAN bus communication error codes stored in the vehicle ECU.
Each OUSIMY rear signal acquisition SAM control module is covered by a long-term quality warranty against manufacturing defects and non-human-induced premature failure. As a 100% direct OE replacement, it features fully compatible plug-and-play installation without extra wiring modification or complex programming adaptation, friendly for DIY installation and professional garage replacement.
