C1711 — Left Front Sensor Circuit Short to Vbat

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

About C1711

C1711 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 C1711 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.

C1711 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 C1711 relates to the left front ultrasonic sensor circuit of the front parking aid system. The Parking Aid Module (PAM) monitors the voltage on each sensor signal circuit, and this code is set when the left front sensor circuit is pulled up to battery voltage (Vbat), indicating the signal wire is shorted to a power feed somewhere in the harness or the sensor has failed internally. The front sensors operate in the same way as the rear set, transmitting ultrasonic pulses and measuring the echo return time so the module can calculate obstacle distance during low speed manoeuvres. When the cod...
