NOTE:

The Evaporative System Diagnostic Check routine will not run if the battery state of charge is too low. To proceed, connect the manufacturer approved Vehicle Battery Conditioner / Power Supply.

The Evaporative System Diagnostic Check routine will initially measure the reference current drawn by the diagnostic module tank leakage pump, and then energize the changeover valve to pressures the fuel tank. The combustible gas detector is then used to identify the source of a leak. The routine takes approximately 10 minutes and may be performed up to 3 times to allow time to test the entire fuel system.
