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.

4.

Touch “START” and operate stop/start system. (engine stop.)

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

1.

On CONSULT screen, select “IPDM E/R” >> “DATA MONITOR” >> “STOP/START STATUS”.

2.

Check that “STOP/START STATUS” indicates “PERMIT”.

Is “PERMIT” indicated?

YES

>> GO TO 9.

NO

>> GO TO 6.

6.

CHECK CUMULATIVE BATTERY DISCHARGE CURRENT

WITH CONSULT

1.

Select “DATA MONITOR” mode of “ENGINE” using CONSULT.

2.

Check that the “CML B/DCHG CRNT” indication.
