About C1796

C1796 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 C1796 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.

C1796 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 drives this solenoid through a dedicated output circuit and monitors the circuit voltage to confirm the solenoid responds when commanded. DTC C1796 sets when the module detects an open circuit on the right rear solenoid output, meaning no current flows when the driver is switched on, pointing to a broken wire, poor connection, or an open solenoid coil. This code is common on Ford and Lincoln vehicles fitted with rear air ...
