ECM 154-4233 10R-8097 Controller Computer Board for CAT Excavator

The 154-4233 is the interlock controller on CAT B-series skid steer and multi terrain loaders - the module that governs start and hydraulic enable interlocks, and the part that water ingress takes out first. Supplied against 154-4233 with 10R-8097 as the remanufactured route.

On a B-series compact loader, the 154-4233 is not the engine controller - it is the interlock ECM, the module that decides whether the machine starts and whether hydraulics are enabled. When it fails, the machine typically does nothing at all: the engine will not crank, or it runs with no hydraulic function and the loader sits dead on site. Water ingress and vibration damage are the usual causes on these machines, and because the module is not externally flashable, the replacement must be matched to the machine rather than flashed afterwards. This page covers the 154-4233 core number and the 10R-8097 remanufactured exchange route, with the programming requirement confirmed against your serial before the unit ships.
