4 To continue testing you will need Miller Tool Kit #6872A, #8382 and #6904 Ultrasonic
Leak Detector.
NOTE: The Fuel Tank must have 1/2 tank of fuel to perform this test.
Perform Evaporative System Pressure Pump Self Test that is specified on the tester
cover.
Warning: Verify the vehicle fuel tank contains at least 3 gallons of fuel.
Attach the DRB III to the vehicle.
Turn the Key On.
At: ENGINE SYSTEM TESTS select: LEAK DETECTION PUMP TEST.
Read instructions and then press ENTER.
At: LEAK DETECTION PUMP TEST select #3 HOLD PSI.
At the vacuum hose going to the LDP, attach and apply a continuous vacuum (i.e. 209
Hg).
Remove Gas Cap.
Install 8382 on the Gas Cap and on the vehicle.
Attach the supply hose from 6872A to 8382.
Attach the power source from the 6872A, clip to Battery(+) and ground clip to
Battery(-).
Set Pressure Hold to Open and set Vent to Open.
Turn Pump Timer On.
To prevent noise from interfering with test, move tool #6872 away from vehicle.
Using the Ultrasonic Leak Detector, start listening for leaks at Gas Cap then proceed
to Rollover Valve, Canister, Leak Detection Pump, and Evap Purge Solenoid.
Were any leaks heard with the Ultrasonic Leak Detector?All
Ye s®Repair or replace leaking component.
Perform VERIFICATION TEST VER-6A.
