Pre-collision warning

[Rickfar]

Lately on my 19 ranger I’ve been driving down the road and all the sudden I get that red flashing pre-collision warning and I’m nowhere near going to hit someone, sometimes there’s nobody even in front of me has anyone else had this happened to them?

Do you have a unbuffed haze of Rain X on the windshield in front of the camera?
That will trigger false alerts

 

[Rickfar]

Never used rain X, the thing I have under the camera is a Garmin mini dash cam but I don’t see how that could interfere with anything

Mine does it once or twice a week now that im driving again in the early mornings, always scares me and im pretty sure it won't do a damn thing if a REAL incident occurs...

If you have Active Cruise Control (ACC)
Then the collision warning uses 2 modules - The CCM and the IPMA

The IPMA uses the view through the windshield - so any glass distortion or haze will throw it off
It also utilizes a IPMA Heater - This is the diagonal line you see through the glass.

The CCM - mounted in the front bumper (If installed) may have some debris or blockage on the front cover, also insure it is secure - both front cover and the CCM itself.
Edit: Forgot to add Dew and Frost on the cover of the CCM will also trigger issues in the system.

Have you checked for any Codes?

You may also try a recalibration of both units via Forscan or Scan Tool

I think there is also a sensitivity setting in the dash menu somewhere for that.

I get warnings from time and time, and once it actually saved my ass. I glanced down at the radio or something, it started screaming at me; someone in front of me had suddenly slowed down to make a turn.

I had it go off this week, I wasnt close to the guy in front of me but I was closing in on him fast, it has come in handy a few times in traffic!
I have a TPM sensor going bad, I just turned 50k miles yesterday ... and I guess its time for things to start falling apart
I have averaged 20mpg this month and 17mpg since Jan.

After my one close call, I think I set mine at full sensitivity. I'd much rather be annoyed, than have a situation where I rely on the 'system' to brake without enough room to stop me.

I’ve gone from 20mg around town to 23 after the DPFE sensor got replaced a month ago. yours may be starting to get clogged. (50k on the clock)

It’s such a PITA to sell such things these days - all those lowball offers showing up in your inbox - people not showing up to see it when they said they would - the annoying dickering over your asking price.

I’d probably give it away too.

Marketplace and the others just suck now days with more scamming than real items, he uses things once and says hey rob you want this, I have gotten e-bike, 6500W generator, commercial air compressor and tons of Tools...
