BRC 000629.12 – Software Execution Delay in Brake Control Unit. John Deere System Advisory.

BRC 000629.12 (BRC 629.12)

Code: 000629.12

Shortcode: 629.12


The error code BRC 000629.12 indicates a fault in the Brake Control Unit (BRC) where the software failed to execute within the allotted time. This type of error can suggest issues with software efficiency or processing delays within the BRC, potentially due to overloaded system tasks or software corruption.


The control unit’s response to this issue is to activate an indicator or alarm. This alerts the operator to a potential malfunction, though it does not immediately affect the brake’s operational capabilities.


  • Software Diagnosis and Updates: Begin by checking for any available updates for the BRC software that might resolve execution delays.
  • System Resource Optimization: Review the configuration to ensure that the BRC is not overloaded with tasks that could hinder its performance. Adjust settings or schedules to optimize resource allocation.
  • Check System Hardware: Assess the hardware supporting the BRC, including processors and memory, for any signs of failure or inefficiency that could impact software execution.
  • Conduct System Resets: If no hardware issues are detected, consider resetting the BRC to clear temporary files and free up system resources.
  • Monitor and Test: After implementing changes, closely monitor the system to ensure that the software executes within the required timeframe during normal operations.


Timely execution of control unit software is critical for maintaining the overall effectiveness and safety of the braking system. Regular system evaluations and maintenance can prevent issues related to software performance and ensure continuous, reliable operation of the Brake Control Unit.
