Issue description
The specific fault code 520445-00 associated with the BCM could not be found. Fault code 520445 is assigned to several different technical conditions: Throttle Valve Actuator Error (partial short circuit), DANA Transmission Configuration Error (internal module reverts to shutdown mode), DEF Pump Motor Communication (erratic/incorrect data), and Intelligent Boom Control (missing jib boom cylinder sensor CAN controller).
Applies to these machines
2 machines- MAGNUM AFS Connect
- Case IH and New Holland equipment utilizing DANA transmissions, Deutz Euro 5 emissions systems (DEF), or intelligent boom lift systems
Check the cause
For the Throttle Valve: Check the wiring harness for a partial short circuit.
For the Throttle Valve: Check the load and output of the actuator.
For the Transmission: Turn the power off and restart the vehicle.
For the Transmission: If the error occurs right after a firmware update, check if the data flash is corrupt.
For the Boom Sensor: Check the sensor connections for a possible wire break.
Repair steps
Repair wiring harness
Throttle Valve: If the failure is present after checking the load and output, repair the wiring harness.
Replace Throttle Valve / Actuator
Throttle Valve: If the short circuit is internal, replace the Throttle Valve / Actuator.
Perform controlled power-down
Transmission: Perform a controlled power-down.
Contact maintenance / Spicer Off-Highway
Transmission: If the code persists, contact maintenance/Spicer Off-Highway to re-flash or replace the internal module.
Repair wire break
Boom Sensor: Repair the wire break to restore CAN controller communication so intelligent boom functionality can be used.
