Electronic Component Identification and Service Diagnostics
The MF 6600 Series electronic component index identifies individual sensors, switches, solenoid valves and control modules used across the transmission, PTO, braking, hydraulic linkage, steering and cab systems. Component-specific connector references assist with locating the corresponding electrical equipment and identifying the correct system when investigating faults.
Separate component references are provided for Autotronic 5 transmission and linkage controllers, Datatronic CCD, the Powershift module, suspended axle and cab controls, and Isobus CAN connections. These references complement the mechanical and hydraulic procedures documented in the relevant workshop sections.
