C1797 — Air Suspension RR Air Spring/Shock Solenoid Output Circuit Short To Battery

System: Chassis  |  Type: Manufacturer-Specific  |  Make: Ford

About C1797

C1797 is a manufacturer-specific chassis diagnostic trouble code recorded for Ford vehicles. It belongs to the C-prefix family of codes, which covers chassis, braking, steering, suspension, or stability-control faults.

When C1797 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) in the monitored circuit.

Scanning & clearing: Chassis (C) codes are stored in the ABS, traction control, or stability-control modules. An enhanced or OEM-level scan tool is usually required to read and clear them.

C1797 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The air suspension control module operates a solenoid valve at the right rear air spring or shock absorber to add and vent air for ride height and damping control. The module switches this solenoid through a dedicated output circuit and monitors the circuit voltage in both the commanded on and off states. DTC C1797 sets when the module detects battery voltage on the right rear solenoid output circuit at a time when the driver is switched off, indicating the circuit is shorted to a battery feed in the harness, connector, or solenoid. This code is most often seen on Ford and Lincoln vehicles fit...
