A/C System Charge Level Test: Notes

There are two methods for doing this procedure. The first method involves the use of a DRB-II and a clamp-on thermocouple (P.S.E. 66-324-0014 or 80PK-1A). Set DRB-II to LH CLIMATE CONTROL, SYSTEM TEST and PARTIAL CHARGE TEST diagnostic topic.

The second method uses a R-134a manifold gauge set, a clamp-on thermocouple (P.S.E. 66-324-0014 or 80PK-1A) and REFRIGERANT CHARGE LEVEL .
