Lexus rx330 206
B1400 code
Can’t find any information about it.

Something with a/c. But the A/C is
running ok.
Is there anything apse to check?

Answer 1

You should double-check the code number, there is no information in the factory service manual for that code. In fact, I did some research, and neither Toyota nor Lexus uses the B1400 code.
