The evaporative emission (EVAP) Service Bay Test raises the engine coolant temperature (ECT) threshold so that the temperature sensitive EVAP diagnosis tests can run while in service environments.

The EVAP service bay test can be used to verify an existing condition and verify that the EVAP system is OK after a repair is completed.
