I have these codes in my 2022 ES250...
B1160 Short in curtain shield airbag RH squib circuit
B1166 status Current/History: open in curtain shield airbag (LH) squib circuit.
0 confirmed codes, 0 pending codes, 0 permanent codes..

What does this mean? Should I get it looked at?
I cleared the codes for now and rescanned it and they didn't come back..
I will drive the car for a few days and see if they come back.
The airbag light turns on and off (does not stay ON) when I turn the ignition on.
I assume it is not that serious but I am surprised to have airbag related code in this vehicle.

 

Car should still be under warranty, I'd take it in for sure. While it may be something silly as a bad battery, you don't need to mess around with safety related faults, especially while under warranty.

 

Thanks.
Still got 3 more years warranty.
Will see if it comes back and take it in once I see it.

 

Check in a couple of days if they come back. I bet you these codes are there from the factory.

 

Did 30 miles and they didn't come back.
I do however have B2620 ecu power source circuit system voltage low same as last time.

 

Did you listen to the radio with the engine off? It may drop the voltage.

 

The car was sitting for a few hours.
I didn't listen to the radio.
