The document provides a summary of fault codes for the MID 130 transmission control unit. It lists parameter IDs, proprietary parameter IDs, and subsystem IDs that may generate fault codes, along with a page reference for more details on each one. Parameter IDs include sensors for range cylinder position, split cylinder position, clutch cylinder position, clutch wear status, air pressure, and more. Subsystem IDs include solenoid valves and PWM valves that control transmission functions. This provides technicians with a starting point to research specific fault codes for the MID 130 transmission control module.
