Battery Condition Initial Setting (i-stop setting) Procedure A [WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5), WITH CYLINDER DEACTIVATION (SKYACTIV-G 2.5), SKYACTIV-G 2.5T]

Caution

• 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 terminal, 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 terminal (it is necessary to leave battery undisturbed for approx. 6 to 48 h to stabilize battery charge condition).

• If the negative battery terminal is disconnected, specific information stored in the PCM will be erased. Therefore, perform the following procedure after reconnecting.

Purpose

Step

Procedure

Caution/Note

Prior verification of PCM and battery condition

1

Verify the value (BATT_SOC) measured before disconnecting the negative battery terminal.

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 terminal 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.

—

Battery condition verification /completion verification

4

Connect the negative battery terminal and wait for 10 s or more.

Caution

•  negative battery terminal tightening torque: 4.0—6.0 N·m {41—61 kgf·cm, 36—53 in·lbf}

Note

•  Connect the negative battery terminal before connecting the current sensor connector. If the current sensor connector is connected first, the PCM may mistakenly recognize a signal from the current sensor and learn the battery condition incorrectly.

5

Connect the current sensor connector.

—

6

Switch the ignition ON (engine off) and wait for 15 s or more (within 1 min.).

—

7

VERIFY i-stop INDICATOR LIGHT (GREEN) AND i-stop WARNING LIGHT (AMBER) FLASHING CONDITION

•  Press the i-stop OFF switch for 10 s and verify the flashing condition of the i-stop indicator light (green) and i-stop warning light (amber).

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

•  When the i-stop OFF switch is pressed, the illumination condition of the i-stop warning light (amber) changes to flashing of either the i-stop indicator light (green) or the i-stop warning light (amber).

8

Switch the ignition off.

—

ISC learning

9

Close the bonnet.

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. As a guide, apply pressure to the radiator hose and if the radiator has warmed up, engine warming is complete.

10

Start the engine.

11

Warm up the engine completely with no electrical load.

Steering angle sensor initialization setting

12

Turn the steering wheel lock-to-lock.

Note

•  Perform steering angle sensor initialization setting because the initial value stored in the EPS control module is reset.

13

Switch the ignition off.

ISC learning verification

14

Perform the following procedure within 25 s.

1.  Switch the ignition ON (engine off) and within 5 s, long-press the i-stop OFF switch for 3 s or more. (The i-stop warning light (amber) illuminates.)

2.  Start the engine.

3.  Long-press the i-stop OFF switch one time.

4.  Verify that the i-stop warning light (amber) stop illuminating and the i-stop indicator light (green) starts flashing.

―  If the amber light continues to illuminate, the procedure was performed incorrectly, therefore repeat the procedure from Step 1. (Prior verification of PCM and battery condition)

Note

•  Although the i-stop indicator light (green) may flash a few times right after the engine is started, then the i-stop warning light (amber) starts illuminating.

15

Maintain the idle status (no electrical load) until the i-stop indicator light (green) turns off.

—

16

After the i-stop indicator light (green) turns off, switch the ignition off.

—

i-stop control operation verification

17

Start the engine and verify that the i-stop indicator light (green) is turned off.

—

18

Verify the i-stop control operation using the following procedure.

EC/Russia specs.

1.  Vehicle is traveling at a speed of 4 km/h or more.

2.  Stop the vehicle and verify that the engine stops via the i-stop control and then restarts.

Except EC/Russia specs.

1.  While the vehicle is traveling at a speed of 4 km/h or more, verify that the i-stop indicator light (green) illuminates.

2.  Stop the vehicle and verify that the engine stops via the i-stop control and then restarts.
