About C1739

C1739 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 C1739 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) in the monitored circuit; and a sensor-related fault — the reported value from the named sensor is out of spec.

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.

C1739 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

DTC C1739 is a manufacturer specific chassis code reported by the parking aid module on Ford vehicles, including the Falcon and Territory, and similar codes in this range are used by other manufacturers for their parking sonar systems. The front bumper carries multiple ultrasonic parking sensors, typically outer and centre sensors on each side, and the module monitors each sensor circuit for plausible electrical values. C1739 is set when the module detects battery voltage on the right front centre sensor circuit, meaning the signal wiring or the sensor itself is shorted to a power feed. When t...
