About C1911

C1911 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 C1911 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.

C1911 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 Ride Control RF Shock Actuator circuit is part of the electronically controlled adaptive suspension system, where the suspension or air ride control module commands a solenoid actuator inside the right front damper to vary shock firmness in real time. DTC C1911 sets when the control module detects that the right front shock actuator control circuit is shorted to battery voltage, sensing the circuit pulled high when it should be controlled by the module driver. The actuator is a variable solenoid that changes damping by altering an internal valve in response to a pulse width modulated comma...
