pre- Collision sensor on the blink!

Hello everyone, It’s been a while. I have been in and out of Hospital dealing with cancer. Anyhow I think my pre-collision sensor is not working! After having minor repairs to my front bumper My pre-collision warnings are no longer occurring. I even tried approaching from behind at a rapid rate of speed and nothing. This is dangerous though I will not recommend. I read somewhere that if it isn’t working it should show up as a warning on the dash. So I am not sure. I tried finding a turn on or off part in the menu or dash listings to no avail. does anyone have any ideas? btw, all the other sensors in the front bumper are working like paking and lane assist. Any ideas?

To turn the Pre-Collision System (PCS) on or off on the Lexus LS500 using the center cluster (Multi-Information Display), follow these steps:
Turning PCS Off

Navigate to Settings: Use the arrow buttons on the left side of your steering wheel to scroll through the Multi-Information Display (MID) until you reach the gear icon(settings menu).
Select PCS: Scroll down or over until you highlight "PCS".
Access Sub-menu: Press and hold the "OK" button on the steering wheel until the sub-settings appear.
Disable the System: Select the PCS icon again and press the "OK" button.
Confirm: When a prompt appears asking for confirmation, select "Yes" and press "OK".
- Indicator: An amber PCS warning light will illuminate on the dashboard to confirm the system is disabled.

Turning PCS On

Manual Activation: Follow the same navigation steps above, select "PCS," and choose "ON".

Adjusting Sensitivity
While in the PCS settings menu, you can also change the Warning Timing (sensitivity) to "Far," "Middle," or "Near" to control how early the system alerts you to potential hazards.
