Lexus RX (RX 350L, RX450h) 2016-2026 Repair Manual: Fail-safe Chart
FAIL-SAFE CHART
If a problem occurs in the power steering system, the power steering assist will be stopped or the amount of power assist will be decreased to protect the system.
Power Steering System| Malfunction | Fail-safe Operation | EPS warning light | Buzzer |
|---|---|---|---|
| Power steering assist stops or assist amount is limited | Red or yellow | Sounds intermittently or once |
| Power steering assist is temporarily limited | Yellow | Sounds once |
HINT:
- If the power steering assist stops, the EPS warning light comes on (red).
- If the amount of power assist is reduced, the EPS warning light comes on (yellow) and a vibration or sound may occur.
- The amount of power assist may be decreased to prevent the motor and ECUs from overheating if the steering wheel is continuously turned when the vehicle is either stopped or being driven at a low speed, or if the steering wheel is kept at either full lock position for a long time. In such cases, the amount of power assist returns to normal when the steering wheel is not turned for approximately 10 minutes with the engine idling.
- If the battery is not sufficiently charged or the voltage decreases temporarily, the amount of power assist will be reduced and the EPS warning light will come on. In such cases, the amount of power assist returns to normal when the battery voltage recovers.
