Brake Hold Operated Indicator Light Circuit [11/2021 - ]: Description

WARNING: This page is about a different car, the 2025 Lexus NX 350h, 2024 Lexus NX 350h, 2023 Lexus NX 350h, and 2022 Lexus NX 350h. However, it is still accessible from the selected car via links, so may be relevant.

The brake hold operated indicator light illuminates when the brake hold system is operating (vehicle stopped due to brake fluid pressure hold) and turns off when the brake hold system operation is finished (brake fluid pressure decreases).

The brake hold system may not operate depending on vehicle conditions even when the system is in standby mode and the brake hold standby indicator light is illuminated.

If there is a system malfunction that causes brake hold control to be prohibited, when the vehicle is under the following conditions and the brake hold switch (electric parking brake switch assembly) is pressed, the brake hold operated indicator light blinks.

Vehicle Conditions:
1. The driver door is closed.
2. The driver seat belt is fastened.

HINT:

When the ignition switch is turned off during brake hold operation, control stops.
If brake hold control does not operate even when the vehicle stops, depress on the brake pedal again firmly to stop the vehicle.
If brake hold control still does not operate, confirm the conditions for brake hold control to operate.
