P2684 Mercury Code - Actuator Supply Voltage 'C' Circuit/Open
Quick Answer
The Powertrain Control Module (PCM) monitors the transmission solenoid circuits by supplying voltage to the solenoids through this circuit, then checking for voltage returning from the solenoids through each of the individual solenoid control wires. Common causes include Faulty Transmission Solenoids, Transmission Solenoids harness is open or shorted, Transmission Solenoids circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
