Check your 12v.

 

Thanks for reply.
Battery seems to be Ok.
12,3v no load 14,7v running.
But now "Time to reset " screen go in and out . line getting lit up or going dark for no reason.
Will go to Midas to check CCA on battery tomorrow.

 

You are describing electrical/electronic issues. They may be related to one component (radio/display), or multiple components, horn, brake, lights, etc. Often times when there are multiple electrical gremlins, battery and negative cable has inconsistent contact with the ground (body of the car). Need to clean and securely attach the cable.

If the issue is with the radio, you might need to diagnose it and consider your options of replacing it versus looking for someone who might repair it.

Good luck.
P.S. you described the symptoms in a confusing way, so if you like a more specific response, consider rephrasing and cleaning up your sentence structure.
Respectfully...

 

Thank you John for reply.
Went out and check battery 575 CCA no problem , charging system OK too.
Contact seemed to be solid . But line under Time Until Reset going dark or light up randomly.
any ideas ?

 

Sway warning is meant to deter fatigued driving. It detects the number of time vehicle crossed the lanes and sets the alarm. I don't remember what I've read in the manual about reset time. You may or may not be able to reset it while driving, possibly by stopping and turning the vehicle off. I personally never care about this feature and I think it's disabled on mine.

What was your battery's resting voltage and what voltage does it hold while cranking? What did you use to measure the CCA?

 

To check CCA went to auto parts store and they used their battery checker to see and print out CCA capacity.
Voltage was 12.4 volt before starting and about 10.5 during cranking (it was so fast my miter is slow to reflect actual voltage)
I don't care about sway warning but line under Time Until Rest is going in and out for no rime or reason.
Thanks again for responding to my concerns. Made appointment with local Lexus dealer will see what he has to say.
