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 the actuator before checking for mechanical binding and adaptation requirements.

Useful checks before replacing parts

Compare actuator command, current draw, position feedback, learned travel limits, and gate movement during controlled shift tests.
Inspect actuator binding, linkage alignment, gear selector mechanism, voltage drop, connector fit, and calibration or adaptation state.
Check whether the performance fault is load-dependent, temperature-dependent, or appears after service or battery disconnect.
