DTC B1422/22 Compressor Lock Sensor Circuit
SYSTEM DESCRIPTION
The ECM sends an engine speed signal to the A/C amplifier via CAN communication and BEAN communication.
The A/C amplifier reads the difference between compressor speed and engine
speed. When the
difference becomes too large, the A/C amplifier determines that the compressor
locks, and turns the
magnetic clutch off.

Due to natural language speech recognition technology, this system
enables recognition of a command when spoken naturally. However,
the system cannot recognize every variation of each command.
In some situations, it is possible to omit the command for the procedure
