This TSB provides detailed instructions for a new LEV II EVAP System
Check function using the Diagnostic Tester. The LEV II System Check
allows the Diagnostic Tester to display the fuel tank vapor pressure as
the EVAP VSV and the CCV are operated in a specific six-step pattern.
Problems with the EVAP system are quickly isolated by observing the

procedure using the LEV II System Check (LEV II SYS CHECK) is described
in this bulletin. This function is available using a Diagnostic Tester
with version 11.0a software (or newer
