DTC B1423 PRESSURE SWITCH CIRCUIT

CIRCUIT DESCRIPTION

Detection Item:

The ECM and A/C amplifier communicate via BEAN.

The pressure switch sends the appropriate signals to the A/C amplifier when the A/C refrigerant pressure drops too low or rises too high. When the A/C amplifier receives these signals, it outputs signals through the A/C amplifier to turn the magnet clutch relay off and turns the magnetic clutch off.
