I've been searching the forums and on Facebook and can't find a fix. I have air suspension wired up too so take the into consideration. About 4 months after my install of air. My Blind spot mirrors stopped working entirely. The button doesn't light up. Nothing happens when it's pushed and no errors on the screen saying "bsm error". It's like it got unplugged or a fuse blew to it. Also at the same time my TPMS will not reset. I have the light on but it will not go away if I push the reset button. Air in my tires is all good and I have NO spare in my trunk. Could this have set it off? Last thing is pretty recently my analog clock resets and will be maybe 6-7 hours off. My digital clock is correct but my analog one is doing it's own thing. I can literally watch it move itself 4-5 hours ahead. Anyone have any idea? I'm on a stock battery. Should I maybe got a bigger battery? Are there fuses to the BSM that I should check? Thanks!

 

your fuseboxes are under the dash in the drivers footwell and under the engine bay. your owners manual will have a diagram for the fuses.

 

I was told by Lexus technicians about 10 years ago that adding aftermarket electronics (e.g.: aftermarket remote starter) to today's electrically complex cars (actually yesterday's cars, so it's probably worse for today's even more complex cars) can cause unexpected and unpredictable results, most of which manifest themselves as failures or erratic behavior of seemingly unrelated systems. I'm not sure what "air suspension wired up too" entails, but my guess is that the gremlin lies there.

 

I am not an electrical expert, but I do know that on newer cars you cannot just tap into or piggy back onto the factory wiring like you could in the "old" days due to use of CAN bus (Controller Area Network). Sounds like your air suspension wiring is most likely screwing up the signal data within the CAN bus.

 

I agree with the other members here. Have you tried taking the car back to where the air suspension system was installed for answers? This is not the first time I've heard of these electrical nightmares and overall issues with air suspension. That being said, I would start by searching the forums for other members who did this modification to see if they are experiencing similar issues and directly message them. I doubt the size of the battery is really causing the issue but you can test that theory probably more easily than starting to uninstall and rewire.

 

I doubt it has anything to do with your airride system setup. I'm guessing you're drawing from the fuse box under the hood along with your batter, I have airride and dont have any electrical issues. I also have a dashcam hardwired and a radar hardwired.. I'm using a lot of power and haven't had any issues. I have a feeling whatever you are experiencing should be covered under warranty if its still active. let the dealer take a look.

 

I too have had a dash cam and a radar detector hard wired with no issues but to rule out that the air suspension system product or more particularly, installation of the system is not the root cause is just silly. There are common examples with electrical issues tied to these systems even with OEM applications like Land Rovers, etc all the time. Either way, a dealership absolutely has the right to refuse 'free or warrantied' service for electrical issues especially when they started to occur after the installation of the aftermarket air suspension system...it sometimes depends from dealer to dealer. I've been refused warranty work with my old Honda regarding sounds I heard with the suspension, just because it was lowered on aftermarket springs instead of ASPEC springs they offered when the root cause was tied to the rotors/brakes! Its just common sense and why all the fine print in the warranties exists and often discussed on car forums for clarification. I would definitely start with the company which installed the air suspension before escalating to a dealership even if it has been 4 months...that's not very long at all. I'm sure if they are a good business who cares about customer satisfaction, they could look everything over at the very least. Sorry for your troubles Thicccluna, honestly...I would be infuriated! BTW, what brand was the air ride you chose to go with?
