C1760 is an OBD-II diagnostic trouble code meaning “Air Suspension Rear Height Sensor Signal Circuit Failure.” C1760 is a manufacturer-specific chassis code indicating the suspension control module detected an invalid signal from the rear ride-height sensor on an air-suspension-equipped vehicle. The height sensor reports the vehicle's rear ride height so the system can level the vehicle and adjust the air springs. When this signal is faulty or out of range, automatic leveling is disabled and the suspension warning light comes on, sometimes with the vehicle sitting low or unevenly. Confirm against the factory manual since the definition varies by maker. This code is most commonly reported on 2007-2017 Lexus LS (LS460, LS460L, LS600h, LS600hL), with repair costs ranging from $1,500 to $5,000.
