Brake, vsc off, trac and abs lights all came on after car wash

[silver4est]

2002 sr5, only had a few days with no troubles. Went to car wash today as it’s sunny and 45°, self wash with sprayer, sprayed under car, wells and whole body. Did not spray under the hood.
When I turned the car on I got the abs, vsc off, trac and brake lights all on, there is no check engine light on. (Yup it works, I checked)
Also have a a Greddy unit that reads speed, temp, o2 etc plugged in OBDii port since I got the truck Monday.

I looked on google and many posts ask about rain, but no info to why. Also saw a post about scan tools failing a CAN test/connection could trigger the lights. Something about it erases the zero point calibration?

Advice? Waiting till it dries to see if thy go off.
What does rain or water have to do with the lights/sensors? Could my Greddy have had a miscommunication and caused it?

The '01/'02 trucks have an integrated ABS/Booster/Brake/Traction control unit. A failure in one of the ABS wheel speed sensors would cause the problem you are seeing...

Hopefully somebody can chime in to help you read the codes to figure out what is wrong (it won't be an OBDII code, it will be an ABS code).

I’m curious if I do the zero point calibration if that will fix it. I’ll get it scanned

Another thing to note, when I turn the key it takes several cranks to start, enough that I worry it might not start, cranks fast/strong does not feel like low power.

Also has auto locks when driving and they have stopped auto locking.

Coincidence?

Thanks for the help and insight!

How old is your truck's battery? I'd take it to a shop like Autozone and have it tested. An old battery caused power lock strangeness like you're experiencing and long crank times in my fiance's BMW 325i.

No clue, new to me runner. I did read that bad battery or alternator can trigger brake lights. It appears to have good power, if I tap gas pedal while cranking it fires right up, least the one time I tried it so far

Can I scan abs through obd2?

My 4Runner has taken about 1.5-2 seconds to start since new. Longer than any other non-carbureted I have driven, but has never caused a problem. It might be normal (give a count one-one-thousand, two-one-thousand and see how long it really is).

Auto locks? That means aftermarket alarm. Start with figuring out what is going on with that...

Sounds as your problems started after washing, You might give it a chance to dry out. You could also look at all the places you sprayed water for connectors that got wet, use a water displacing spray or compressed air to dry them out.

After it sitting for a couple hours, started it up and no more lights, I’ll have to Inspect the sensors and plugs/wires see if water can short anything out.

Still have to tap gas pedal to get it to start easier

Clean your throttle body and Idle Air Control solenoid.

As for the ABS lights after car wash. You probably have a front ABS sensor or connector that doesn't seal well.
