P26E9
Actuator Supply Voltage D Circuit High
The fourth actuator supply rail is above the expected voltage. 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.
