C1762 — Air Suspension Rear Height Sensor High (SE) Signal Circuit Short To Battery

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

About C1762

C1762 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 C1762 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) in the monitored circuit; a signal or supply voltage higher than the expected operating range; 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.

C1762 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 C1762 is a Ford air suspension code indicating the suspension control module has detected the rear height sensor signal circuit shorted to battery voltage. The rear height sensor operates within a low voltage signal window supplied by the module, so a signal line sitting at system voltage tells the module the wiring has made contact with a power feed rather than reporting true rear ride height. Typical causes are a chafed harness contacting a battery feed along the frame rail, water or corrosion bridging terminals in a rear connector, or incorrect splicing during towbar and trailer wiring ...
