Q: What does code P285E mean?

Shift Fork A Actuator Circuit High. P285E indicates that the transmission control module (TCM) has detected an abnormally high voltage on the electrical circuit that controls Shift Fork A's actuator, which is part of an automated manual or dual-clutch transmission. The TCM expects the actuator circuit to draw current within a specific range, and a high-voltage condition means the circuit is either open, shorted to power, or the actuator itself has failed.
