Tech Tips
ADD COOLANT
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 |
|
INSPECT FOR COOLANT LEAK
Remove the radiator cap.
CAUTION:
Do not remove the radiator cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.
Fill the radiator with coolant and attach a radiator cap tester.
Warm up the engine.
Using a radiator cap tester, increase the pressure inside the radiator to 137 kPa (1.4 kgf/cm2, 19.9 psi), and check that the pressure does not drop.
If the pressure drops, check the hoses, radiator and water pump for leaks. If no external leaks are found, check the heater core, cylinder block and cylinder head.
Install the radiator cap.
