Default So washed my car today - could not start properly

So first time this has happened, I washed it like usual at the self power wash place, maybe water got in some place but this is what happened... I push the start button and nothing will happen, no crank no start nothing. I have to try a couple of time before it would start. It would go to accessory or something but no signs of life from engine.But once it started it was fine, no erros codes no lights, came home after a few hours went out, tried to start car, same problem, this time, VSC system PCS system etc, brake hold will not work, similar to what was discussed in another thread. https://www.clublexus.com/forums/ls-...t-working.html

So observations, since there was no crank and no sound and when pressing the start button it went to accessory mode (like when you press it twice without depressing the brake pedal) it can be inferred that there is an issue with the brake switch or whatever it is. I read about it here: https://www.clublexus.com/forums/ls-...and-b2090.html

So no issues driving it except brake hold did not work, when my friend read the codes there were 10 codes.. lots of nonsensical stuff, crankshaft codes... cam shaft coees 10+ codes with no rhyme or reason, so we cleared the codes and one code remained which was B2090. which also went away after we started the car again and i have driven it to and from dinner since with no issues.

Did the car washing have something to do with it, what could be the possible causes.

THANKS GUYS

This may be an occasion of Radio Frequency Interference when an interfering signal prevented the car from recognizing the key. Your owner's manual explains that this can happen. Often the interfering signals are transitory such as police or military radio transmitters operated in close proximity. You can also experience this when near malfunctioning florissant or mercury vapor lighting. These systems that link starting with RF signal exchanges are subject to this type interruption but they only rarely cause problems. If you have a problem like this the way to overcome it is to use the alternate starting method with the NFC key - see your owner's manual.

But if that's the case I would not be getting the codes I got right?

Did you wash under the hood or near the engine bay? Maybe you sprayed water into some electrical connections?

No hood remained closed. Thus is why it is disturbing of course we know it is an electrical wire or connector issue but if you look at the code above it says brake pedal but I did nothing to the interior. I think I will have to have all the connectors looked at

Check your battery terminals- either you have a loose connector or corrosion on the terminals (probably). Did you get any check engine lights or codes? Assuming of course, if you know your battery is in good shape. If it were me, I;d find the issue cause, "going away" wouldn't be a satisfactory answer for me- as my wife is the one who gets to pilot the 460 most days. I say check the terminals because maybe the water blew into that open side of the bay, happens to be the negative terminal. My bet is just a bad battery or loose terminal.

sorry, I missed the code mention above.

Many times, the terminals will jostle loose going over those "speed bumps"in automatic wash stations, causing the terminal or terminals to wiggle just slightly loose. When the do this while running, the alternator keeps the car running. When you try and crank, the car won't turn over, or click, or even do anything at all. So you open the hood, glance..all looks good -so you close the hood.. maybe the slam bumps the terminal back into place. Car starts. That's the basic idea. It has happened to me before.

Check your starter fuses, relay (failing or loose) continuity, and ground from the solenoid.

By the way, no need for the snippy attitude. Just trying to help.

I would check the voltage on the battery - it may just be coincidental that it acted up immediately following a wash.

Guys an update taking into account all my one off problems I think it’s the throttle body/ throttle position sensor which is in the throttle body.
