About C1847

C1847 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 C1847 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.

C1847 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

DTC C1847 is a manufacturer specific chassis code used on Ford and Lincoln air suspension vehicles, including the Lincoln Continental, Mark VIII, and Navigator. The air suspension control module switches the front air spring inflator (fill) solenoid through a monitored driver output, and C1847 sets when the module detects battery voltage on that output circuit when it should not be present, indicating the wiring or solenoid is shorted to a 12V source. It belongs to the same circuit family as C1845 (general failure) and C1846 (open circuit) for the front inflator solenoid. A short to battery is...
