WARNING: This page is about a different car, the 2004 Suzuki Aerio. However, it is still accessible from the selected car via links, so may be relevant.

Connect manifold gauge set to charging valves.
Run engine and A/C switch ON.
Check continuity between "c" and "d" terminals of A/C refrigerant pressure switch (1) when A/C refrigerant pressure is changed, as shown in figure.
If operation is not as specified, replace A/C refrigerant pressure switch.
