C1744 — Front Sounder Circuit Failure

System: Chassis  |  Type: Manufacturer-Specific  |  Make: Ford

About C1744

C1744 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 C1744 is stored, the module has detected an electrical-circuit fault in the wiring, connector, or driver associated with the named component.

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.

C1744 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

Vehicles fitted with front parking sensors use a separate front sounder, a small speaker usually mounted behind the instrument panel or in a front kick panel, so the driver can distinguish front warnings from rear warnings. The Parking Aid Module (PAM) drives the front sounder directly and monitors the circuit, and DTC C1744 is set when the module detects an open circuit or a short on the front sounder drive circuit. The fault is most often in the wiring or connectors along the long harness run between the module and the sounder, although the sounder itself can fail open. When the code sets, t...
