Vansco 233660 Multiplex Module

The Vansco 233660 is a multiplex module used in heavy‑vehicle control systems, providing 28 sensor or switch inputs and routing signals to 20 output channels with integrated power and network interfaces. Common failure points for this class of modules include degraded input/output contacts, solder joint fatigue on the PCB, and damaged power/ground traces that can cause intermittent signal loss or total module failure. First‑check diagnostics: verify that the module receives correct 12 V (or specified) supply voltage and proper network (CAN/LIN) termination; inspect all I/O connectors for corrosion or loose pins; and review any diagnostic codes from the vehicle’s ECU that reference the multiplex module to pinpoint input/output channel faults.[oss-gpt-20b]
