Vehicle pre collision system (pcs) malfunction/off light will illuminate upon engine start and turn off once several minutes have passed when driving. Light seems to illuminate more often when the temp is <40f. Unknown if the pre collision system is actually working when the malfunction light illuminates.
Multiple events. 2500 miles on vehicle. While driving 70mph in cruise control the pre-collision warning came on and vehicle applied brakes forcefully without any vehicle ahead of my vehicle until I turned off cruise control. After the event the traler brake malfunction statement and warning lights were on. Pre -collision failure light reset after key cycled off and back on. Failure occurred multiple times in multiple driving conditions, currently trailer brake failure light is illuminated. Each time I had to exit or pull over and stop vehicle, cycle key to have warning clear.
Pre-collision system warning light is on stating that the system is off it will not function
Driving truck on freeway with cruise control on at 80-85 MPH. Road was flat and it was a clear sunny day. No cars near the truck and the precollision sensor went off causing the truck to almost emergency brake before I turned cruise control off. There was nothing in front of the truck to cause this. A few weeks before the precolision sensor and lane departure semsor went off and til me the truck needed to be taken to dealer. The sensors have gone off a few times saying they are inoperable.
