C1714 on Lexus
Manufacturer-Specific Chassis Code (Nissan: Rear-Right TPMS Transmitter Malfunction)
C1714 on Lexus vehicles indicates manufacturer-specific chassis code (nissan: rear-right tpms transmitter malfunction). Au7o has documented this code across 2 Lexus models — most commonly on LS, LX. C1714 is a manufacturer-specific chassis code. On Nissan it generally indicates the rear-right tire pressure monitoring (TPMS) transmitter/sensor is malfunctioning, meaning the body control module is not receiving a valid signal from that wheel's pressure sensor. This is a monitoring/convenience fault — the TPMS warning may be active and that wheel's pressure may not display, but it does not directly affect braking or handling. The exact meaning should be confirmed for the specific vehicle. Typical repair costs on Lexus range from $1,500 to $6,000, depending on the specific model and root cause.
Common Causes of C1714
- •Dead or weak TPMS sensor battery (rear-right wheel)
- •Faulty TPMS sensor/transmitter
- •Sensor not registered after tire service
- •TPMS receiver/antenna fault
- •Radio-frequency interference
- •Body control module fault (rare)
C1714 on Lexus by Model
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.
Lexus LX(1 issue)
- AHC (Active Height Control) Suspension Failure2008-2021
The Active Height Control hydraulic suspension on the LX570 develops leaks in the height control actuators, accumulator, and hydraulic lines. The system uses hydraulic fluid under high pressure to adjust ride height, and seals deteriorate over time causing fluid loss. A complete system failure leaves the vehicle stuck at one height setting and triggers warning lights.
