Actuator Supply Voltage C Circuit/Open

Where it lives

For P2684, the circuit described runs through the actuator. The description of P2684 reports the actuator as open.

Check these first

• An open in the actuator supply voltage C circuit
• A blown fuse feeding the actuator supply voltage C circuit
• A short to ground on the actuator supply voltage C circuit
• A corroded or backed out pin in the actuator supply voltage C connector

What to do next

1. Read actuator supply voltage C on a scan tool
2. Check the fuse feeding the actuator supply voltage C circuit
3. Measure voltage on the actuator supply voltage C circuit
4. Test the actuator supply voltage C circuit for open and short faults
5. Repair the actuator supply voltage C wiring if the fuse tests good
6. Clear the code and retest
