What Does C1795 Mean?
The right rear air spring or air shock solenoid output circuit has a general failure. This solenoid controls airflow to the right rear air spring for ride height adjustment. The module cannot properly command the solenoid, preventing height control on that corner. The vehicle may sag or sit high on the right rear, and a suspension warning will be displayed.
Common Causes
30%
Faulty right rear air spring solenoid valve (electrically or mechanically failed)
25%
Wiring harness damage between suspension module and RR solenoid
20%
Corroded or water-damaged connector at the air spring solenoid
15%
Air suspension module output driver failure for RR channel
10%
Mechanical damage to air spring assembly affecting solenoid operation
Diagnostic Steps
1
Command the right rear solenoid on using scan tool bidirectional controls and listen for the solenoid click. Monitor current draw — should be 0.5-1.5A when energized.
2
Disconnect the RR solenoid connector and measure coil resistance — spec is typically 3-10 ohms. Replace if open or shorted.
3
Check for voltage at the solenoid connector when commanding on — should see battery voltage (11-14V) across the pins. No voltage indicates a wiring or module issue.
4
Inspect the wiring harness to the right rear air spring, particularly where it routes along the rear axle, over the differential, and near exhaust components. Look for heat damage, abrasion, and moisture.
5
Examine the connector for corrosion, broken locking tab, or pushed-back pins. Clean and apply dielectric grease.

The most common cause of C1795 (Air Suspension RR Air Spring/Shock Solenoid Output Circuit Failure) is: Faulty right rear air spring solenoid valve (electrically or mechanically failed)
Typical repair costs for C1795 range from $150 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The right rear corner cannot be properly leveled. Handling balance and braking distribution are affected. If the vehicle is visibly leaning, reduce speed and avoid loaded/towing conditions. Have the repair completed promptly to prevent secondary damage to the air spring.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C1795 to identify the root cause.
