About C1199

C1199 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 C1199 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.

C1199 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 Anti-lock Brake System (ABS) module energises hydraulic solenoid valves inside the Hydraulic Control Unit (HCU) to modulate brake pressure at each wheel. The Left Front (LF) inlet, or isolation, valve holds and isolates brake pressure at that wheel during anti-lock and stability events. DTC C1199 is the open circuit specific variant of the left front inlet valve coil fault and is set when the module detects no current flow through that coil circuit, indicating a broken winding or an open in the control wiring. When this code is stored the module disables ABS and typically traction and stab...
