CONNECT CABLE TO NEGATIVE BATTERY TERMINAL
INSPECT FOR FUEL LEAK
Perform the Active Test.
Replace the normal DLC3 cable (12 V specification) for the intelligent tester with the 24 V DLC3 cable.
Note
Be sure to use the 24 V DLC3 cable when connecting the intelligent tester to the DLC3. Using the normal DLC3 cable (12 V specification) will cause damage to the tester.
Connect the intelligent tester to the DLC3.
Start the engine.
Turn the intelligent tester on.
Select the following menu items: Powertrain / Engine / Active Test.
Perform the Active Test.
| Tester Display | Test Part | Control Range | Diagnostic Notes |
|---|---|---|---|
| Test the Fuel Leak | Pressurizing common rail internal fuel pressure, and checking for fuel leaks | Stop/Start |
