DTC B1422/22 Compressor Lock Sensor Circuit

SYSTEM DESCRIPTION

DTC Detection Condition:

The ECM sends a signal to the A/C amplifier via CAN 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.
