SUPPLY PUMP INITIALIZATION PROCEDURE
Tech Tips
After replacing the supply pump and/or the ECM:
The ECM's learned values must be initialized. The engine can be initialized through the intelligent tester or by short-circuiting DLC3 terminals.
Connect the intelligent tester to the DLC3.
Turn the ignition switch to the ON position.
Note
Do not start the engine.
Turn the intelligent tester on.

Start the engine to check if initialization is complete. If the engine cannot be started, repeat the initialization procedures from the beginning (Procedure "A").
Idle the engine for at least 1 minute under the following conditions (Procedure "B"):
The water temperature is 60°C (140°F) or more.
The fuel temperature is 20°C (68°F) or more.
Note
Do not race the engine immediately after starting the engine. After warming up the engine, racing the engine is acceptable.
Tech Tips
The water temperature can be estimated by touching the outlet hose.
The fuel temperature can be estimated by using the ambient temperature as a substitute.
If the water temperature is difficult to estimate, use the intelligent tester and enter the following menu items: Powertrain / Engine and ECT / Data List / Coolant Temp.
Initialization is complete.
