A/C Refrigerant Pressure Switch - Suzuki Ignis Service Manual

A/C REFRIGERANT PRESSURE SWITCH

INSPECTION
1) Check A/C refrigerant pressure switch (1) for continuity at
normal temperature (approximately 25°C (77°F)) when A/C
system has a proper charge of refrigerant and A/C system
(compressor) is under operation. In each of these cases,
switch should show proper continuity.
[A] : LH model
[B] : RH model
2) Check continuity between high and low pressure switch ter-
minals (1) at specified pressure as shown.
High and low pressure switch specification
A : Approximately 200 kPa (2.0 kg/cm
B : Approximately 230 kPa (2.3 kg/cm
C : Approximately 2600 kPa (26 kg/cm
D : Approximately 3200 kPa (32 kg/cm
3) Check continuity between medium pressure switch terminals
(2) at specified pressure as shown as shown.
Medium pressure switch specification
E : Approximately 1100 kPa (11 kg/cm
F : Approximately 1500 kPa (15 kg/cm
Tightening torque
A/C refrigerant pressure switch :
11 N·m (1.1 kg-m, 8.0 lb-ft)
[A] : High and low pressure
[B] : Middle pressure
