Hi guys I just recently purchased a 2001 lexus ls430 for 8k that has 106k miles in the bay area. Silver on black interior with the navigation package and sport suspension. Some issues I need your guys knowledge on is every time I start the car I get a three consecutive chimes and then another one would you guys have any idea what it might be? No warning lights or whatsoever pops up so i am completely clueless what it might be. Fyi the previous owner took out the 6 disk cd changer and replaced with an alpine head unit and my navigation currently doesn't work telling me to insert a disc. Another issue I need some assistance on is that my vsc button doesn't work for some reason thank you for your time into helping me with my problems I would really appreciate any knowledge that you would want to share.

 

Congratulations on your purchase and welcome. It is most likely the nav swap. The chime does not sound engine related. Fix your mechanical issues regarding the VSC and make sure it has had a timing belt / water pump. Nice to hook up the techstream software and check the vehicle if possible.
