U0150 Lost Communication with Side Object Detection Control Module Left
The Side Object Detection Control Module Left has stopped transmitting on the vehicle data bus, so other control units no longer receive its messages. Left-side blind-spot monitoring stops working. Typical causes are loss of power or ground at the module, an open or shorted CAN/LIN bus wire, a connector fault, or an internal module failure.
