ON-VEHICLE INSPECTION
PROCEDURE
1. INSPECT REFRIGERANT PRESSURE WITH MANIFOLD GAUGE SET
HINT:
This is a method where a manifold gauge set is used to help locate the problem.
(a) Read the manifold gauge pressure when the following conditions are met:
Test conditions:
(1) Normally functioning refrigeration system Gauge Reading
