DTC 23 Pressure Switch Circuit

CIRCUIT DESCRIPTION

Detection Item:

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 control assembly receives these signals, it outputs signals via the A/C control assembly to switch OFF the compressor relay and turns the magnetic clutch OFF.
