One of the 4 ABS sensor is out ! take it to the shop and get it check which one is out and then replace that one.

 

I just replaced one but the ABS and Trac light is still on. How do I reset/turn off the light?

 

What is the problem when ABS light gives these codes?
11 - Open or short in solenoid relay circuit
34 - Malfunction LR wheel-speed sensor circuit

Plus, the best way to clear the code is short pins 4 and 13 on the OBDII connector (paperclip), unplug the ABS connector from the ABS control module then turn the key to on (no need to start the car) and pump the brake petal 8 times fast right away, the ABS and Trac OFF light should go off now. Turn off the car and plug back in the ABS connector to the ABS control module.
I have a 2000 Solara but can anyone answer my question? Thx

 

1st, don't try that trick, particularly Toyota the light will come back on if that problem is persist, you have to replace the damage part , the light will automatically clear by itself.

code 11 will come along with any other code.
code 34 means your LEFT REAR ABS sensor is gone

you're unlucky i still have the spare RIGHT REAR ABS sensor "brand new" in bag that i bought 3 years ago.

Dealership or USA markets sell Solara ABS price range from 100-300 $

I have learnt ABS system for Toyota about 6 months, i know exactly whats wrong with it. I have a trick that make those ABS and traction lights go off but the ABS won't kick in.

Here go on Ebay and buy 20$ ABS from China like i did, it works like a charm, i bought 2 ABS for 30$ from China and wow work well boy.
