STOP/START SYSTEM NOT ACTIVATED
Diagnosis Procedure
INFOID:0000000010713098
NOTE:
To use the stop/start system, the vehicle needs to recognize the status of battery. For this reason, the stop/
start system may not be activated immediately after battery change.
1.
CHECK DTC
With CONSULT
Perform “All DTC Reading” with CONSULT.
Is any DTC detected?
YES
>> Perform trouble diagnosis for the detected DTC.
NO
>> GO TO 2.
2.
CHECK STOP/START INDICATOR LAMP
Check stop/start indicator lamp.
Is stop/start indicator lamp blinks slowly?
YES
>> Perform “All DTC Reading” with CONSULT and perform trouble diagnosis for detected DTC.
NO
>> GO TO 3.
3.
PERFORM ACTIVE TEST
With CONSULT
1.
Start the engine and warm it up to normal operating temperature.
2.
Press start/stop OFF switch and check that the switch indicator is ON.
3.
Select “AUTO STOP START” in “ACTIVE TEST” mode of “ENGINE” using CONSULT.

5.
Touch “CANCEL” and restart the engine.
Is stop/ start system activated normal?
YES
>> GO TO 8.
NO
>> GO TO 4.
4.
CHECK STARTER MOTOR OPERATION COUNTER
With CONSULT
1.
Select “STRT OPRTN CNTR” in “DATA MONITOR” mode of “ENGINE” using CONSULT.
2.
Check that the “STRT OPRTN CNTR” indication.
Is the indication less than 250,000?
YES
>> GO TO 5.
NO
>> Replace starter motor. Refer to
STR-24, "HRA2DDT : Removal and Installation"
5.
CHECK IPDM E/R STATUS
With CONSULT
