C1795 – OBD-II DTC

OBD-II DTC C1795 – Air Suspension RR Air Spring/Shock Solenoid Output Circuit Failure

DTC C1795 meaning

DTC C1795 refers to a fault in the air suspension system, specifically indicating an issue with the rear right air spring or shock solenoid output circuit. This diagnostic trouble code (DTC) is triggered when the vehicle’s onboard diagnostic system detects a malfunction in the electrical circuit that controls the air spring or shock absorber on the rear right side of the vehicle. The air suspension system is responsible for maintaining ride height and comfort by adjusting the air pressure in the springs or shocks based on load and driving conditions.

DTC C1795 symptoms

Common symptoms associated with DTC C1795 may include:

• Warning lights on the dashboard, such as the air suspension warning light.
• Uneven ride height, with the rear right side sitting lower than the other corners.
• Harsh or bumpy ride quality due to improper suspension function.
• Increased noise from the rear suspension area.
• Possible air leaks or hissing sounds from the air spring or shock assembly.

DTC C1795 causes

Several factors can lead to the triggering of DTC C1795, including:

• Faulty rear right air spring or shock solenoid.
• Wiring issues, such as damaged or corroded wires in the solenoid output circuit.
• Connector problems, including loose or corroded connections.
• Faulty air suspension control module.
• Air leaks in the rear right air spring or associated components.

DTC C1795 seriousness

DTC C1795 is considered a moderate to serious issue, as it directly affects the vehicle’s suspension system. If left unaddressed, it can lead to:

• Decreased ride quality and comfort.
• Increased wear on suspension components.
• Potential safety hazards due to compromised handling and stability.
• Further damage to the air suspension system, leading to more costly repairs.

How to diagnose DTC C1795

To diagnose DTC C1795, follow these steps:

1. Use an OBD-II scanner to confirm the presence of DTC C1795.
2. Inspect the rear right air spring and shock solenoid for visible damage or leaks.
3. Check the wiring and connectors for signs of wear, corrosion, or disconnection.
4. Test the solenoid operation using a multimeter to ensure it is receiving the correct voltage.
5. Examine the air suspension control module for faults or error codes.
6. Perform a continuity test on the solenoid output circuit to identify any breaks.

How to fix DTC C1795 step-by-step instructions

To fix DTC C1795, follow these step-by-step instructions:

1. Clear the DTC using an OBD-II scanner and take the vehicle for a test drive to see if the code returns.
2. If the code reappears, inspect the rear right air spring and shock solenoid for any visible damage.
3. Repair or replace any damaged wiring or connectors found during the inspection.
4. Test the solenoid for proper operation and replace it if it is faulty.
5. Check for air leaks in the rear right air spring and repair or replace as necessary.
6. Recheck the air suspension control module for any faults and replace if needed.
7. After repairs, clear the DTC again and perform a final test drive to ensure the issue is resolved.
