Service Bay Test: Description

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. When the EVAP tests are run the Service Bay Test will indicate a pass or will indicate a specific DTC has failed. The EVAP Service Bay Test can be used to verify an existing condition and verify that the EVAP system is okay after a repair is completed.
