Hi everyone hope the below helps;

Picked up this 2016 Kluger Grande and drove it 500kms to get it home. [Photo 1]

While using the Cruise Control on the long stretches the PCS (Pre-Crash Safety System) alarm sounded and the 2 x Warning lights came on causing the Cruise Control to stop working.

This vehicle has Dynamic Radar Cruise Control Mode.

Page 408 and 412 in the Toyota Owners Manual gave some insight. [Photo 2]

I searched Dr Google and found a POSSIBLE cause. [Photos 3 -4]

After opening the bonnet and removing the cover trim that protects the bonnet latch etc I found an after market wiring loom in front of the Radar obstructing it and the surface dirty. [Photo 5]

I removed the after market LED Toyota emblem.  Cleaned the surface of the Radar,  installed the OEM Toyota Emblem (the previous owners kept the original emblem),  [Photos 6-9]

I have since done some extensive travelling on the Highways out this way and the PCS Warning Light did not come on and the Dynamic Radar Cruise Control behaved accordingly!

SUMMARY:

Save yourself some coin by investigating yourself before going to the Dealership or Auto Electrician.

Hope this helps, apologies if there is already a thread on this particular issue as I am still trying to navigate this helpful Kluger Forum.

Safe Travels..  Steve
