About C1106

C1106 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 C1106 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.

C1106 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 Traction Control Disable Switch is the driver operated control, usually a momentary push button, that requests the traction control system be turned off. The ABS or traction control module monitors the switch signal circuit to detect when the switch is pressed. DTC C1106 sets when the module detects battery voltage on the disable switch circuit at a time it should not be present, indicating the signal wire has shorted to a power feed. With this code present the module may interpret the switch as continuously pressed, traction control may be disabled or behave erratically, while normal hydr...
