P288A Park Lock/Pawl Actuator Circuit High

Voltage on the park lock or pawl actuator control line is above the expected window. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
