i-stop INDICATOR LIGHT (GREEN) FLASHES
DESCRIPTION
•  i-stop indicator light (green) remains flashing during idling.*1
•  i-stop indicator light (green) remains flashing during i-stop.
POSSIBLE CAUSE
Note
•  If the brake pedal depression is insufficient, the i-stop indicator light (green) illuminates and the i-stop function operates by increasing brake pedal depression. (AT)*1
•  If in gear while i-stop is operating, the i-stop indicator light (green) flashes continuously. (MT)
•  If the driver’s door is open while i-stop is operating, the i-stop warning light (green) flashes continuously. (European (L.H.D. U.K.) specs.)
•  i-stop operation conditions are not met.*1
i-stop function operation conditions are not set*1
•  False detection of insufficient brake depression (fluid pressure). (AT)
―  Brake fluid pressure sensor (built-into DSC HU/CM) malfunction

*1  :The illumination status of the i-stop indicator light (green) differs depending on the PCM software version.

Diagnostic Procedure

STEP

INSPECTION

RESULTS

ACTION
1
VERIFY DTC
•  Retrieve the PCM, DSC HU/CM and instrument cluster DTCs using the M-MDS.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [PCM (SKYACTIV-G 1.5, SKYACTIV-G 2.0)].)
(See DTC TABLE [DSC HU/CM].)
(See DTC TABLE [INSTRUMENT CLUSTER].)
No
AT:
•  Go to the next step.
MT:
•  Go to Step 3.
2
INSPECT BRAKE FLUID PRESSURE SENSOR
•  Inspect the brake fluid pressure sensor.
•  Is there any malfunction?
Yes
Go to Step 5.
No
Replace the DSC HU/CM.
(See DSC HU/CM REMOVAL/INSTALLATION [L.H.D.].)
(See DSC HU/CM REMOVAL/INSTALLATION [R.H.D.].)
Go to the next step.
3
VERIFY IF MALFUNCTION IS DUE TO EFFECT OF VEHICLE USE CONDITION
•  Verify how the customer drives the vehicle by asking the customer the following:
―  If the shift lever is shifted to a position other than neutral during i-stop, the i-stop indicator light (green) flashes to indicate that the vehicle is in gear. (MT)
•  Is the shift lever shifted to a position other than neutral during i-stop operation?
Yes
Explain to the customer that the vehicle is normal, provide the conditions for i-stop operation, and advise the customer how to use it.
No
Go to the next step.
4
INSPECT NEUTRAL SWITCH
•  Inspect the neutral switch.
•  Is there any malfunction?
Yes
Repeat the inspection from Step 1.
•  If the malfunction is not resolved, replace the PCM.
Go to the next step.
No
Replace the neutral switch.
(See NEUTRAL SWITCH REMOVAL/INSTALLATION [M66M-D].)
Go to the next step.
5
Verify the test results.
•  If normal, return to the diagnostic index to service any additional symptoms.
•  If a malfunction remains, inspect the related Service Information and perform the repair or diagnosis.
―  If the vehicle is repaired, troubleshooting is completed.
―  If the vehicle is not repaired or additional diagnostic information is not available, replace the PCM.
