C1703 — Right Rear Sensor Circuit Failure

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

About C1703

C1703 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 C1703 is stored, the module has detected 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.

C1703 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 C1703 is set by the Parking Aid Module (PAM) when it detects a general circuit failure on the right rear outer parking aid sensor, typically an open circuit or no response from the sensor when it is commanded to transmit. The rear parking aid system uses ultrasonic sensors mounted in the rear bumper to measure the distance to obstacles when reverse is selected, and the module checks each sensor circuit for opens, shorts, and missing responses every time the system operates. When the right rear outer sensor circuit fails this monitoring, the module sets C1703, disables the entire parking ai...
