C1844 Mercury Code - Air Suspension Secondary Front Inflator Solenoid Output Circuit Failure
Quick Answer
The diagnostic trouble code (DTC) C1844 indicates a malfunction in the air suspension system, specifically related to the secondary front inflator solenoid output circuit. Common causes include Faulty Inflator Solenoid: The solenoid itself may be defective, preventing it from opening or closing as needed, Wiring Issues: Damaged or corroded wiring in the solenoid circuit can disrupt the signal from the control module, Faulty Air Compressor: If the air compressor is not functioning properly, it may not provide the necessary air pressure to the suspension system. 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 C1844 Mercury Description
The diagnostic trouble code (DTC) C1844 indicates a malfunction in the air suspension system, specifically related to the secondary front inflator solenoid output circuit. This solenoid is responsible for controlling the airflow to the air suspension bags at the front of the vehicle, which helps maintain the proper ride height and comfort level. When this code is triggered, it typically suggests that the solenoid is either not receiving a signal from the control module or is unable to operate correctly due to an electrical fault.
Common Causes of C1844 Mercury
- Faulty Inflator Solenoid: The solenoid itself may be defective, preventing it from opening or closing as needed.
- Wiring Issues: Damaged or corroded wiring in the solenoid circuit can disrupt the signal from the control module.
- Faulty Air Compressor: If the air compressor is not functioning properly, it may not provide the necessary air pressure to the suspension system.
- Control Module Malfunction: The vehicle's control module may have a fault that prevents it from sending the correct signals to the solenoid.
- Air Leaks: Leaks in the air suspension bags or associated components can lead to insufficient air pressure, causing the system to fail.
Symptoms of C1844 Mercury
- Uneven Ride Height: The front of the vehicle may sit lower or higher than the rear, indicating a malfunction in the air suspension.
- Warning Lights: The dashboard may display warning lights related to the air suspension system or general suspension warnings.
- Poor Ride Quality: Drivers may experience a rough or bumpy ride due to the inability of the suspension system to adjust properly.
- Increased Tire Wear: Uneven suspension can lead to abnormal tire wear patterns, necessitating more frequent tire replacements.
- Noise from Suspension Components: There may be unusual sounds coming from the suspension system, such as hissing or popping, indicating air leaks or component failure.
How to Fix C1844 Mercury
- Diagnostic Scan: Begin with a thorough diagnostic scan to confirm the C1844 code and check for any additional codes that may provide further insight into the issue.
- Visual Inspection: Conduct a visual inspection of the wiring and connectors associated with the inflator solenoid for signs of damage, corrosion, or disconnection.
- Test the Solenoid: Use a multimeter to test the solenoid for continuity and proper operation. If it fails the test, replacement is necessary.
- Check the Air Compressor: Ensure that the air compressor is functioning correctly and providing adequate pressure to the suspension system.
- Repair or Replace Components: Based on the findings, repair any damaged wiring, replace the solenoid or air compressor as needed, and clear the DTC to see if it returns.
Cost to Fix C1844 Mercury
The typical repair costs for addressing a C1844 code can range from $200 to $800, depending on the specific repairs needed. This estimate includes parts such as a new inflator solenoid (approximately $100 to $300) and labor costs, which can vary significantly. Labor rates typically range from $80 to $150 per hour, with metropolitan areas and dealerships often charging more, while independent shops may offer lower rates. Diagnosis time can also vary, so it’s advisable to check local rates for a more precise estimate. Regular maintenance and prompt attention to warning codes can help mitigate more extensive repairs down the line.
