BATTERY CONDITION INITIALIZATION SETTING (i-stop SETTING)

• If the engine is started with the bonnet open, the i-stop function will not operate until the engine is restarted with the bonnet closed (not system malfunction). If the engine is started with the bonnet open, close the bonnet and restart the engine after the ignition is switched off once.

• If a vehicle with an i-stop non-operation condition is brought in, the malfunction will not be resolved by simply performing the battery condition initial setting (i-stop setting). Verify the PID “BATT_SOC” value and if the value is less than 75%, recharge the battery. (See BATTERY RECHARGING.)

• If the “BATT_SOC” value has not been verified before disconnecting the negative battery cable, perform battery condition initial setting (i-stop setting) after performing the battery inspection.

• The “BATT_SOC” value is displayed “0%” because the battery charge condition is not stabilized after connecting the negative battery cable (it is necessary to leave battery undisturbed for approx. 6 to 48 h to stabilize battery charge condition).

Purpose	Step	Procedure	Caution/Note
Prior verification of PCM and battery condition	1	Verify the value (BATT_SOC) measured before disconnecting the negative battery cable. When BATT_SOC value is 75% or more. • Go to the next step. When BATT_SOC value is not verified or the value is less than 75% • Perform battery inspection. (See BATTERY INSPECTION.)	—
2	Verify that 5 min or more have elapsed since the negative battery cable was disconnected.	Caution • It is necessary to leave the battery undisturbed for 5 min or more because the voltage is not stabilized, depending on the battery usage condition, and the PCM cannot determine the “BATT_SOC” value correctly.
3	Disconnect the current sensor connector. If the current sensor connector has already been disconnected, go to the next step.	—

When i-stop indicator light (green) flashes ― Go to the next step. When i-stop warning light (amber) flashes ― Perform the battery inspection. (See BATTERY INSPECTION.) When i-stop warning light (amber) illuminates ― Procedure is performed incorrectly. Switch the ignition off and repeat the procedure from Step 1 (Prior verification of PCM and battery condition).

Note • If the engine is not warmed up completely the ISC learning will not finish. ― Warm-up is not completed even if the low engine coolant temperature indicator light (blue) turns off.
