Understand this system
Use this section to confirm what this error system covers, which device families it typically appears in, and how the main fault families are grouped before you move into individual codes.
Common fault families
Software/Config
1 code indexed under software/config diagnostics.
Thermal
1 code indexed under thermal diagnostics.
Hardware
1 code indexed under hardware diagnostics.
Motor Control
1 code indexed under motor control diagnostics.
First checks before code lookup
Use these system-level checks first when the exact code is not yet confirmed. The goal is to narrow the failure path before you open a specific code page.

Common codes to start with
Use these as the fastest entry points when the system has not yet been narrowed to a single failure path.
Priority codes to review first
These codes usually deserve faster attention because they are more disruptive or more likely to hide upstream system issues.
