PRECAUTIONS BEFORE SERVICE
LEARNING FUNCTION OF GDI ENGINE
1. Purpose
On the GDI engine equipped cars, when replacement of the ECU (for engine control) or resetting
of the battery* has been performed, an idle learning function of the ECU (for engine control) will
be required.
The idle learning function will be completed by running the engine at idle by the following procedure.
NOTE:
*: Disconnection of ECU (for engine control) battery backup power supply (disconnection of battery
terminals or ECU connectors)
2. Idle Learning Procedure
(1) Start the engine, and warm up the engine until its coolant temperature reaches 85°C or higher.
When the engine coolant temperature is 85°C or higher, you have only to turn the ignition
switch to the ON position.
(2) Turn the ignition switch to the LOCK (OFF) position, and stop the engine.
(3) After lapse of ten or more seconds, restart the engine.
(4) Run the engine at idle for ten minutes under the following conditions.
DTransmission: Neutral (P range for automatic transmission)
DAir conditioner and heater: Not operational
DEngine coolant temperature: 83°C or higher
(5) Stop the engine.
(6) Restart the engine, and run it at idle for ten minutes under the following condition.
DTransmission: Neutral (P range for automatic transmission)
DAir conditioner: Operational (Temperature set at “maximum cool”, fan at high speed, and
windows fully opened)
DEngine coolant temperature: 83°C or higher
(7) Repeat steps (5) and (6).
NOTE:
1) When the atmospheric temperature is 20°C or more and the air conditioner has continuously
been operated, step (7) may be omitted.
2) During idling operation of the engine in steps (4) and (6), when engine operation switches
from lean operation to stoichiometric operation, engine stall can occur. In this case, clean the
throttle body (throttle valve) thoroughly, and then repeat step (1) and the subsequent steps.
