Perform Battery Condition Initial Setting (i-Stop Setting)

WARNING: This page is about a different variant/trim than selected.

CAUTION:

If the engine is started with the hood open, i-stop will not operate until the hood is closed and the engine is restarted. (Not system malfunction) If the engine was started with the hood open, switch the ignition OFF, close the hood, and then restart the engine.
Without M Hybrid
(i-stop non operation) If the vehicle is brought in with i-stop not operating, the malfunction cannot be resolved by only performing the battery condition initial setting (i-stop setting). Verify the PID BATT_SOC value and if the value is less than 75%, perform a battery inspection. (See BATTERY INSPECTION .)
If the [BATT_SOC] has not been verified before disconnecting the negative battery terminal, perform the battery condition initial setting (i-stop setting) after performing the battery inspection.
Directly after connecting the negative battery terminal, a BATT_SOC value of [0%] is displayed because the battery charge status is unstable. (It is necessary to leave vehicle for 6 to 48 hours until battery charge status stabilizes)

NOTE: T3

If the diesel particulate filter regeneration control is not performed at a traveled distance of 10 km or less, the PCM performs the diesel particulate filter regeneration control while the setting procedure for the battery condition initial setting (i-stop setting) is performed to stabilize the exhaust gas purification. (Regular regeneration control)
While the regular regeneration control is performed, a condition in which high engine speed is continued for a specified period of time. (Up to 22 min (depends on engine coolant temperature)

1. Verify that the BATT_SOC value measured when the vehicle is in the shop is 75% or more.	1. Using the M-MDS, verify that the PID [BATT_SOC] value is 75% or more.	O	O	O
	2. In the following cases, perform a battery inspection. (See BATTERY INSPECTION .) [BATT_SOC] value is less than 75% [BATT_SOC] value cannot be verified	O	O	O
2. Have the [BATT_SOC] value determined by the PCM.	1. Disconnect the negative battery terminal and wait for 5 min or more. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) NOTE: It is necessary to leave the lead-acid battery undisturbed for or more because the voltage may not be stabilized depending on the battery usage condition and it could cause the PCM to determine the BATT_SOC value incorrectly.	O	O	O
2. Have the [BATT_SOC] value determined by the PCM.	2. Disconnect the current sensor connector.	O	O	O
3. Have the PCM learn the battery condition.	1. Connect the negative battery terminal and wait for 10 s or more. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .)	O	O	O
	2. Connect the current sensor connector. NOTE: If the current sensor connector is connected first before connecting the negative battery terminal, the PCM may mistakenly recognize a signal from the current sensor and will monitor the driver for approx. 3 min learn the battery condition incorrectly.

	3. Switch the ignition ON (engine off) and wait between 15 s to 60 s.	-	O	O
	4. Press and hold the i-stop OFF switch for approx. 10 s.	-	O	O
	5. Verify that the i-stop warning light (amber) illumination changes to the i-stop indicator light (green) flashing. If the i-stop warning light (amber) does not turn off, it is possible that the procedure was performed incorrectly, therefore, perform the procedure again from the beginning. If the i-stop warning light (amber) flashes, perform a battery inspection. (See BATTERY INSPECTION .)	-	O	O

	5. Press and hold the i-stop OFF switch for approx. 3 s.	-	O	O
	6. Wait for 30 s while idling (with no electrical load).	-	O	O
	7. Perform engine racing for a minimum 10 times and a maximum 20 times. Then, wait for 30 s while idling (with no electrical load). After the flashing i-stop indicator light (green) turns off, switch the ignition OFF. If the i-stop indicator light (green) does not turn off, it is possible that there is a problem with the M Hybrid system, therefore, perform an inspection of the M Hybrid system. NOTE: The flashing i-stop indicator light (green) may turn off early and the i-stop control setting verification may be completed early depending on the battery condition.	-	-	-
	8. Maintain the idling condition (with no electrical load) until the i-stop indicator light (green) flashing turns off.	-	O	O

6. Perform an i-stop control operation verification.	1. Switch the ignition ON (engine on).	-	O	O
	2. Accelerate to a vehicle speed of 15 km/h in approx. 5 s without operating the steering wheel.	-	O	O
