Where it lives

For P285B, the actuator sits on the circuit this code reports. The description of P285B reports the actuator as open.

Check these first

• An open in the shift fork A actuator circuit
• A short to ground or voltage on the shift fork A actuator control wire
• A failed shift fork A actuator
• A corroded shift fork A actuator connector

What to do next

1. Read shift fork A actuator status on a scan tool
2. Command the shift fork A actuator on and off
3. Test the shift fork A actuator circuit for open and short faults
4. Check the shift fork A actuator connector pins
5. Replace the shift fork A actuator if the circuit tests good
