extremely high humidity inside the trailer may result in false test results.
• If running a Pretrip Test on a trailer loaded with sensitive cargo, monitor
the load temperature during the test as normal temperature control is
suspended during pre-trip operation.
• Always perform Pretrip Tests with the trailer cargo doors closed to
prevent false test failures.
