Fuel Pressure Leak Down Test

To test for fuel leaks, using the DRB II (or equivalent) scan tool, perform the following procedure:

1. Turn the ignition switch to the ON position.
2. Access the ASD Fuel System Test. This will activate the fuel pump and pressurize the fuel system.

NOTE: The ASD Fuel System Test will continue for 7 minutes or until the test is stopped with the scan tool, or until the ignition switch is rotated to the OFF position.
