About C1327

C1327 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 C1327 is stored, the module has detected a signal or supply voltage lower than the expected operating range.

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.

C1327 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 Antilock Brake System (ABS) module monitors the brake fluid level switch input to ensure sufficient hydraulic fluid is available for normal brake system operation. DTC C1327 is set when the ABS module detects a signal indicating the brake fluid level switch is in the low position for a calibrated period, or when the input is electrically implausible, suggesting insufficient brake fluid level or a circuit fault. When set, the module may disable ABS, traction control, or stability control functions as a safety precaution, and a brake warning lamp is usually illuminated. Because this code can...
