PILOT QUANTITY LEARNING
• "Pilot Quantity Learning" is performed when injector
assemblies have been replaced and injector
compensation codes have been registered. "Pilot
Quantity Learning (Detail)" is performed when there
are engine problems but no DTCs are output and the
technician wishes to clear the learned values and
have the vehicle relearn the values.
• This procedure uses the intelligent tester to perform
"Pilot Quantity Learning".
• When replacing the injector assembly, engine or
ECM, perform this procedure after performing injector
compensation (manual ID code registration).

It takes time to clear the learned values and perform
learning for all cylinders.
• This procedure uses the intelligent tester to perform
"Pilot Quantity Learning (Detail)".
• When replacing the injector assembly, engine or

HINT:
After replacing the supply pump and/or ECM:
• If the engine is defective or stalls immediately after
startup, the learned values of the ECM must be
initialized. The engine can be initialized through the
intelligent tester or by connecting DLC3 terminals.
• If the engine starts normally, initialization is not
necessary. Perform the steps labeled procedure "A"
and procedure "B" only.
