Lexus Troubleshooting Questions? Ask a Lexus Expert
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.In order to get some idea what may be causing the problem you are having the first thing you are going to need to do is to scan the computer system and see if there are any fault codes setting in the Electric Park Brake System. The light staying on is likely causing the battery to drain. If you can get the scan done and post back with the results I will try and help you determine the cause.
