C1875 — Air Suspension RF Air Spring Solenoid Output Circuit Short To Battery

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

About C1875

C1875 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 C1875 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.

C1875 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 sets ride height at each corner by operating a dedicated air spring solenoid valve that admits or releases air. DTC C1875 sets when the module detects that the right front air spring solenoid output circuit is shorted to battery voltage, meaning the control wire is reading supply voltage when the module should be controlling it through a low side driver. The module watches the voltage and current on that output and flags a short to battery when the circuit stays high or behaves abnormally. When this code is stored the right front corner may sag or sit too high...
