i-stop INDICATOR LIGHT (GREEN) FLASHES

DESCRIPTION

•  i-stop indicator light (green) remains flashing during idling.

POSSIBLE CAUSE

i-stop function operation conditions are not set

•  Brake depression (fluid pressure) is insufficient.

―  Brake fluid pressure sensor (built-into DSC HU/CM) malfunction

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.

30	i-stop INDICATOR LIGHT (GREEN) FLASHES
DESCRIPTION	• i-stop indicator light (green) remains flashing during idling.
POSSIBLE CAUSE	i-stop function operation conditions are not set • Brake depression (fluid pressure) is insufficient. ― Brake fluid pressure sensor (built-into DSC HU/CM) malfunction 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.

Diagnostic Procedure

STEP	INSPECTION	RESULTS	ACTION
1	VERIFY i-stop INDICATOR LIGHT (GREEN) FLASHING CONDITION • Does the i-stop indicator light (green) flash while the vehicle is stopped?	Yes	Go to the next step.
1		No	Go to Step 3.
2	INSPECT IF MALFUNCTION CAUSE IS INSUFFICIENT BRAKE PEDAL DEPRESSION OR INABILITY TO RESTART ENGINE • Depress the brake pedal. • Does the i-stop function operate after the i-stop indicator light (green) changes from illumination to flashing?	Yes	The system is normal. (malfunction due to insufficient brake depression when vehicle is stopped)
2		No	Go to the next step.
3	VERIFY DTC • Retrieve the PCM and DSC HU/CM DTCs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-G 2.0].) (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [SKYACTIV-G 2.0].) (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].)
3		No	Go to the next step.
4	INSPECT BRAKE FLUID PRESSURE SENSOR • Inspect the brake fluid pressure sensor. (See BRAKE FLUID LEVEL SENSOR INSPECTION.) • Is there any malfunction?	Yes	Replace the DSC HU/CM. (See DSC HU/CM REMOVAL/INSTALLATION.)
4		No	Replace the PCM. (See PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)
5	Verify the test results. • If normal, return to the diagnostic index to service any additional symptoms. (See SYMPTOM DIAGNOSTIC INDEX [SKYACTIV-G 2.0].) • 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. (See PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)
