3.PRE-CHECK
a.

Measure the battery voltage.

Standard voltage:

11 to 14 V (ignition switch off)


HINT:
·

If the battery voltage is below 11 V, recharge or replace the battery. Until charging current decreases to 5 A or less, if integrated current value still does not increase to threshold value*1 or higher, initialize integrated current value*2.

-

*1: Refer to Description of Integrated Current Value Threshold

Click hereEngine / Hybrid System>STOP AND START>STOP AND START SYSTEM>SYSTEM DESCRIPTION

-

*2: Using the GTS, perform Integrated Current Value Initialization.

Click hereEngine / Hybrid System>STOP AND START>STOP AND START SYSTEM>REGISTRATION


·

When the battery is replaced, even if stop and start control operates immediately after replacement, stop and start control prohibition may temporarily continue due to charging capacity learning that occurs within several trips.




b.

Check the fuses and relays.


c.

Check the connector connections and terminals to make sure that there are no abnormalities such as loose connections, deformation, etc.

9.CONFIRMATION TEST
9.CONFIRMATION TEST
a.

Warm up the engine.


b.

Turn the air conditioning system off.


c.

Drive the vehicle for 5 to 40 minutes.

CAUTION:

When performing Confirmation Driving Pattern, obey all speed limits and traffic laws.



d.

Stop the vehicle and confirm that the engine is stopped by stop and start control when all of the following conditions are met:

·

Steering wheel centered

·

Shift lever in D

·

Brake pedal depressed

·

Stop and start indicator illuminated


HINT:

If the engine is not stopped by stop and start control, air fuel ratio learning and idle speed learning are necessary. Allow the engine to idle for 3 minutes and check that the engine idle speed is within 50 rpm of the target idle speed.



e.

Move the shift lever to N and confirm that the engine starts.
