Actuator Supply Voltage C Circuit Low

Where it lives

For P2685, the actuator sits on the circuit this code reports. The description of P2685 reports a fault at the actuator.

Check these first

• A short to ground on the actuator supply voltage C circuit
• Low voltage feeding the actuator supply voltage C circuit
• A failed actuator on the actuator supply voltage C circuit
• High resistance in the actuator supply voltage C return

What to do next

1. Read actuator supply voltage C on a scan tool
2. Measure voltage on the actuator supply voltage C circuit
3. Check the actuator supply voltage C circuit for a short to ground
4. Inspect the actuator supply voltage C connector and wiring
5. Repair the actuator supply voltage C wiring if the circuit tests good
6. Clear the code and retest
