19267,Regarding the "ParkSense Unavailable" warning, there are a few steps you can take to troubleshoot the issue:
- Check the sensors: Ensure that there is no dirt, debris, or obstructions covering the parking sensors. Clean them gently with a soft cloth if necessary.
- Inspect the wiring: Examine the wiring connected to the parking sensors for any signs of damage or disconnection. Ensure that all connections are secure.
- Check the fuse again: Although you mentioned changing the F49 fuse, it's worth double-checking that the new fuse is not blown. If it is, replace it with a new fuse of the correct amperage.
- Perform a reset: Try performing a system reset by disconnecting the car battery for a few minutes and then reconnecting it. This can sometimes resolve electronic glitches.
Thank you for the breakdown advice. I will place the Stelvio on a lift this Saturday and will check everything you mentioned. I am sure it is probably a fuse somewhere or a relay. Strange to think that I have the Stelvio in the shop for a 4 wheel balance and alignment the same day this issue cropped up. I know that it is probably coincidence.
Update... My friend and I took the black boxes out. They were nothing more than resistors glued to a heat fin. The same resistors that stop your turn signals from hyper-blinking when you install LEDs on an older automobile. Really crap... and grounded. Once we took those out we went down the rabbit hole and we dug into the wiring harness. We noticed that Sigma Automotive cut wires and rewired to other wires in the harness. So, we desoldered and re-soldered with heat shrink all the wires into their correct spots. Everything works perfectly now. I have more lights in the tails lights than before. Taking out that poorly done wiring job fix most of the issues I have had.
Of course, I used MES to reprogram the tail lights to EU lights. Worked perfectly.
Oh, how do I use MES to scan for errors? I could not figure that out. I checked Park Sense and it was on and no issues reported there. But how do I perform a complete scan?
As always, much appreciated,
