Hint:
When the air conditioning system functions properly, dtc b1400/00 is output.


Hint:
*1: Dtc b1422/22 (compressor lock sensor circuit) is indicated only for a currently occurring malfunction for 2grfe.
To confirm dtc b1422/22, perform the following steps:
*2: Compressor and pulley for 2az-fe, compressor and magnetic clutch for 2gr-fe
