i-stop WARNING LIGHT (AMBER) ILLUMINATES

DESCRIPTION

•  i-stop warning light (amber) remains illuminated while engine is running.

POSSIBLE CAUSE

System off recognized due to false detection of i-stop OFF switch

•  i-stop OFF switch malfunction

―  i-stop OFF switch malfunction

―  Short to ground in wiring harness between cluster switch terminal D and instrument cluster terminal 1V (VIN: JM0 KG2W2A*# 100001—199999)

―  Short to ground in wiring harness between cluster switch terminal B and instrument cluster terminal 1V (VIN: JM0 KG2W2A*# 200001—)

Instrument cluster malfunction

•  i-stop warming light (amber) illumination circuit in instrument cluster disabled

•  CAN communication line malfunction between instrument cluster and PCM

DESCRIPTION	• i-stop warning light (amber) remains illuminated while engine is running.
POSSIBLE CAUSE	System off recognized due to false detection of i-stop OFF switch • i-stop OFF switch malfunction ― i-stop OFF switch malfunction ― Short to ground in wiring harness between cluster switch terminal D and instrument cluster terminal 1V (VIN: JM0 KG2W2A# 100001—199999) ― Short to ground in wiring harness between cluster switch terminal B and instrument cluster terminal 1V (VIN: JM0 KG2W2A# 200001—) Instrument cluster malfunction • i-stop warming light (amber) illumination circuit in instrument cluster disabled • CAN communication line malfunction between instrument cluster and PCM

Diagnostic Procedure

STEP	INSPECTION	RESULTS	ACTION
1	VERIFY DTC • Retrieve the PCM and instrument cluster DTCs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)].) (See DTC INSPECTION [INSTRUMENT CLUSTER].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [PCM (SKYACTIV-D 2.2)].) (See DTC TABLE [INSTRUMENT CLUSTER].)
1		No	Go to the next step.
2	DETERMINE FALSE ILLUMINATION OF i-stop WARNING LIGHT (AMBER) • Does the i-stop operate while the i-stop warning light (amber) is illuminated?	Yes	False illumination of i-stop warning light (amber) can be considered the cause. Go to the next step.
2		No	Go to Step 4.
3	DETERMINE IF MALFUNCTION CAUSE IS INSTRUMENT CLUSTER WARNING LIGHT ILLUMINATION CIRCUIT OR ERROR SIGNAL FROM PCM • Switch the ignition ON (engine off). • Access the instrument cluster PID WL+IL and illuminate and turn off the warning light in the instrument cluster using the M-MDS. (See ACTIVE COMMAND MODES INSPECTION [INSTRUMENT CLUSTER].) • Does the i-stop warning light (amber) illuminate or turn off according to the M-MDS operation? (See ACTIVE COMMAND MODES TABLE [INSTRUMENT CLUSTER].)	Yes	Repeat the inspection from Step 1. • If the malfunction is not resolved, replace the PCM. (See PCM REMOVAL/INSTALLATION [SKYACTIV-D 2.2].) Go to Step 6.
3		No	Replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
4	INSPECT i-stop OFF SWITCH • Inspect the i-stop OFF switch. (See i-stop OFF SWITCH INSPECTION [SKYACTIV-D 2.2].) • Is there any malfunction?	Yes	Replace the cluster switch, then go to step 6. (See CLUSTER SWITCH REMOVAL/INSTALLATION.)
4		No	Go to the next step.
5*	DETERMINE IF MALFUNCTION CAUSE IS i-stop OFF SWITCH SIGNAL OR OTHER • Switch the ignition off. • Disconnect the cluster switch and instrument cluster connectors. • Inspect for continuity between cluster switch terminal D (wiring harness-side) and body ground. (VIN: JM0 KG2W2A# 100001—199999) • Inspect for continuity between cluster switch terminal B (wiring harness-side) and body ground. (VIN: JM0 KG2W2A# 200001—) • Is there continuity?	Yes	Repair or replace the wiring harness which is shorted to ground, then go to the next step.
5*		No	Replace the instrument cluster, then go to the next step. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
6	Verify the test results. • If normal, return to the diagnostic index to service any additional symptoms. (See SYMPTOM DIAGNOSTIC INDEX [SKYACTIV-D 2.2].) • 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-D 2.2].)
