C1810 Mercury Code - Air Suspension Height Sensor Delta Out Of Range

Quick Answer

The 2 rear height sensors receive a 5-volt reference voltage from the Vehicle Dynamics Module (VDM), both sensors share a common return path. Common causes include Faulty Air Suspension Height Sensor, Air Suspension Height Sensor harness is open or shorted, Air Suspension Height Sensor 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.

Code C1810 Mercury Description

The 2 rear height sensors receive a 5-volt reference voltage from the Vehicle Dynamics Module (VDM), both sensors share a common return path. The RR sensor sends the suspension height voltage back to the VDM. The LR sensor sends the suspension height voltage back to the module. The VDM monitors the 2 height sensors and makes adjustments to the rear suspension based on sensor input. The ECM sets the OBDII code when the Air Suspension Height Sensor is not to factory specifications.

Frequently Asked Questions about C1810 Mercury Code

1. What does the OBDII code C1810 mean on a Mercury vehicle?

The code C1810 indicates that the air suspension height sensor is detecting a delta (difference) in readings that is out of the expected range.

2. What are the common symptoms of the C1810 code?

Symptoms include an uneven ride height, sagging suspension, a stiff or bouncy ride, and the suspension warning light illuminating on the dashboard.

3. What causes the C1810 code to appear on a Mercury?

Common causes include a faulty air suspension height sensor, wiring issues such as damaged or corroded connections, or a failing suspension control module.

4. Can a faulty air compressor cause the C1810 code?

While a faulty compressor can impact suspension performance, the C1810 code specifically relates to height sensor readings, not compressor function.

5. How do I diagnose the C1810 code?

Start by inspecting the air suspension height sensor and its wiring for damage or corrosion. Use a scan tool to check sensor readings and confirm if theyâ€™re outside the specified range.

6. Can I drive with the C1810 code active?

Driving with this code is possible, but itâ€™s not recommended as it can lead to uneven suspension performance, reduced ride comfort, and potential damage to suspension components.

7. How is the C1810 code fixed?

Repairs typically include replacing the faulty height sensor, repairing damaged wiring or connectors, or reprogramming/updating the suspension control module if necessary.

8. How much does it cost to fix the C1810 code on a Mercury?

Repair costs vary but typically range from $100 to $300 for sensor replacement or wiring repairs. Additional diagnostics or module programming may increase the cost.

9. Can I clear the C1810 code without fixing the problem?

Clearing the code without addressing the root cause will only make it return, as the system will still detect the out-of-range sensor readings.

10. What happens if the C1810 code is ignored?

Ignoring the C1810 code can lead to further suspension issues, increased tire wear, and reduced vehicle stability, especially during cornering or uneven road conditions.
