C1760 on Lexus
Air Suspension Rear Height Sensor Signal Circuit Failure
C1760 on Lexus vehicles indicates air suspension rear height sensor signal circuit failure. Au7o has documented this code across 1 Lexus model — most commonly on LS. 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. Typical repair costs on Lexus range from $1,500 to $5,000, depending on the specific model and root cause.

- •Faulty rear ride-height sensor

Lexus LS(1 issue)
- Air Suspension Strut and Compressor Failure2007-2017
The pneumatic air suspension system on the LS460 and LS600h develops leaks in the air springs, causing the vehicle to sag overnight or drop on one corner. The air compressor runs excessively to compensate for leaks and eventually burns out. Complete air suspension failure leaves the car sitting on the bump stops.
