CASE M-Series Crawler Dozers – Fault Codes and Diagnostic Reference

The manual serves as a comprehensive troubleshooting and fault-isolation reference for CASE M-Series Crawler Dozers, enabling technicians to identify electrical, mechanical, and communication failures precisely.
It organizes fault codes into six major ranges and provides a detailed fault-to-description table, including:

• Vehicle and sensor faults (1000–1999) — seat switch, alternator, speed sensors, voltage references, UCM voltage, calibration errors.

• Engine faults (3000–3999) — coolant temperature, oil pressure, injector circuits, EGR, turbo actuator, DPF differential pressure, and regeneration logic.

• Hydraulic and joystick faults (4000–5999) — solenoid open/short circuits, joystick axis range errors, and plausibility faults.

• Optional and CAN-BUS faults (8000–9999) — leveling control errors, DM1 BAM packet timeouts, SCR communication, and logical data-retrieval errors.
