HINT:
  1. When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the intelligent tester. Then after installing the new ECM, perform all of the initializations/registrations for the "Learning Values Write" function by following the instructions shown on the tester display.
  2. After replacing fuel injector(s), perform both the "Injector Compensation" and the "Pilot Quantity Learning Values Reset" functions using the intelligent tester. If fuel injector(s) and the ECM are replaced at the same time, perform the same initializations/registrations as when replacing the ECM.
  3. After replacing the air fuel ratio sensor, perform the "A/F Sensor Compensation Reset" function using the intelligent tester. If the air fuel ratio sensor and the ECM are replaced at the same time, perform the same initializations/registrations as when replacing the ECM.
  4. After replacing the DPF catalytic converter, perform the "DPF Deterioration Record Clear" function using the intelligent tester. If the DPF catalytic converter and the ECM are replaced at the same time, perform the same initializations/registrations as when replacing the ECM.
  5. After replacing the engine assembly, perform both the "Injector Compensation" and the "Pilot Quantity Learning Values Reset" functions using the intelligent tester. If the engine assembly and the ECM are replaced at the same time, perform the same initializations/registrations as when replacing the ECM.
  6. If the "Learning Values Save" or "Learning Values Write" function has failed, input manually the injection compensation codes and the vehicle mileage using the "Injector Compensation" and "Vehicle Mileage Write" functions by following the instructions shown on the intelligent tester display.
  7. The items related to the DPF system appears on the intelligent tester display only for vehicles with the DPF system.
