C1A23 on Land Rover
Manufacturer-Specific Chassis Fault
C1A23 on Land Rover vehicles indicates manufacturer-specific chassis fault. Au7o has documented this code across 1 Land Rover model — most commonly on Discovery. C1A23 is a manufacturer-specific chassis code (in the Nissan/Infiniti C1Axx family) whose exact definition is not well documented in public references. Codes in this range typically relate to driver-assistance/radar systems or ride-height/suspension sensing. In general it indicates the module detected a fault with a connected sensor or circuit in one of these chassis subsystems. The specific component and cause should be confirmed using the factory service manual or a brand-specific diagnostic tool rather than assumed. Typical repair costs on Land Rover range from $300 to $800, depending on the specific model and root cause.
Common Causes of C1A23
- •Faulty sensor in the affected chassis/driver-assist subsystem
- •Damaged wiring or connectors
- •Sensor blockage, misalignment, or needed calibration
- •Corrosion or water intrusion at connectors
- •Low system voltage or poor ground
- •Related control module fault
C1A23 on Land Rover by Model
Land Rover Discovery(1 issue)
- L462 Discovery Air Suspension Height Sensor Failure2017-2025
The current-generation L462 Discovery continues the air suspension tradition with its own set of issues. The ride height sensors are particularly prone to failure, giving incorrect height readings that cause the vehicle to sit at uneven heights. The sensors are located at each corner and exposed to road debris. Failure of one sensor affects the entire system's ability to level the vehicle.
