My 2013 Lexus 350 RX won't start. It say BSM not available. Any ideas?

 

Mods, please move this thread to the RX forum.


AFAIK, BSM is Blind Spot Monitor. There is no reason why a problem with that system should prevent your vehicle from starting.

When do you see the BSM message- when you push the start button? How long have you had this starting problem? Does the engine crank when you push the button? Maybe you have a weak battery. Have you tried jump-starting it? If that doesn't work, you have to get it towed to a dealer or a good indy shop for diagnosis. Good luck!

 

I have had this problem several times and was very frustrated. What I found is the battery is getting used and not being recharged fully. So I attached a charger to it and let it slowly recharged overnight. Once I did this and the battery was fully charged, I have not had a no start BSM error since. Give it a try!

 

What is the system voltage with the engine running at idle?
If it's not around 13.2-13.5v the alternator is not properly charging the battery.
With the engine off it should read around 12.2-12.4v.
Check the battery connections for corrosion.

 

thanks, the connections are just fine, no corrosion. Will have to look into charging voltage. Did not think of that.
