Hello,

My car started beeping once in a while, while driving (same sound as when someone didn't buckle their seatbelt). Any idea what it could be?
I already tried:
- All the doors are properly closed.
- Trunk and gas door are properly closed.
- Seatbelts are buckled (for the people in the car).
- Hood is properly closed.
- Oil level is good (oil change due in 4k km).

I forgot to add that when it beeps, the temperature indicator flashes 4-5 times (not the warning light, the indicator that tells the temperature of the outside (there are no warning light that are lit)).

This sounds like a bad Vehicle System Control Module but to be sure we need to run a CAN scan which is easy to do. You can get a CAN scanner (Controller Area Network) from Amazon from about $32.00.

Here is a video to show you how:

Here is how to replace the Vehicle System Control Module in case you need it. Check out the images (below). Please let us know what happens.
