About C1841

C1841 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 C1841 is stored, the module has detected an open (broken or disconnected) electrical path 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.

C1841 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 C1841 is a manufacturer specific chassis code used on Ford and Lincoln vehicles fitted with air suspension, such as the Town Car, Expedition, and Navigator. The air suspension disable switch, mounted in the luggage compartment or behind a side trim panel, lets the operator power the system down before towing, jacking, or hoisting. The air suspension control module feeds a sense voltage through the switch circuit and monitors the return signal, and it sets C1841 specifically when it detects an open circuit, meaning no current path exists through the switch and its wiring. This differs from ...
