P2685 Fault Code

Actuator Supply Voltage C Circuit Low

• What does that mean?
• Symptoms
• Causes
• Solutions

The P2685 fault code indicates a low voltage condition in the actuator supply voltage C circuit. This can affect the performance of various actuators in the vehicle, potentially leading to improper operation or failure of components reliant on this voltage.

What are the symptoms of the P2685 code?

When the P2685 fault code is present, drivers may experience symptoms such as:

• Malfunctioning actuators that do not operate correctly
• Warning lights illuminated on the dashboard
• Decreased performance in systems that rely on the actuator
• Inconsistent behavior in vehicle functions related to the actuator.

What causes the P2685 code?

Several factors can lead to a low voltage condition in the actuator supply voltage C circuit. These may include:

• Damaged wiring or connectors in the circuit
• A malfunctioning actuator drawing excessive current
• A weak or failing battery
• Poor ground connection within the circuit
• Defective power distribution components such as relays or fuses.

How to fix P2685?

To resolve the P2685 fault code, consider the following steps:

• Inspect the wiring and connectors for any signs of damage or corrosion and repair or replace as necessary.
• Test the actuator for proper function and replace if it is faulty.
• Check the battery voltage and condition; replace if weak.
• Ensure that all ground connections are secure and free of corrosion.
• Inspect and test fuses and relays related to the actuator circuit and replace any faulty components.
