Inspection
NOTE: Procedure 1 — Ambient Temperature below 21 °C (70 °F).
NOTE: Proper A/C system diagnosis on a vehicle’s compressor is dependent on correct refrigerant system charge and tested in ambient temperatures above 21°C (70°F). Perform the following steps to achieve normal operating pressures.
Drive the vehicle or run the engine until it reaches normal operating temperature.Inspection
NOTE: Procedure 2 — Ambient Temperature between 21 °C (70 °F) and 38 °C (100 °F)
Run the engine until it reaches normal operating temperature.![]() |
