Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not replace a single actuator from the control error alone; verify the full command-feedback sequence.

Useful checks before replacing parts

Compare commanded gear position, actual feedback, actuator current, clutch actuator state, gate position, and shift timing.
Inspect actuator movement, linkage alignment, mechanical binding, clutch release, position sensor data, wiring, and adaptation status.
Review companion actuator, position, clutch, and control-error codes to identify the primary failed part of the sequence.
