A/C System Charge Level Test: Notes

There are 2 methods for doing this procedure. The first method involves the use of a scan tool and a clamp-on Thermocouple (P.S.E. 66-324-0014 or 80PK-1A). Set scan tool to LH CLIMATE CONTROL, SYSTEM TEST and PARTIAL CHARGE TEST diagnostic topic. See SCAN TOOL METHOD.

The second method uses a R-134a manifold gauge set, a clamp-on Thermocouple (P.S.E. 66-324-0014 or 80PK-1A) and the REFRIGERANT CHARGE LEVEL  table. See MANIFOLD GAUGE SET METHOD.
