Diagnostic Procedure

I-STOP WARNING LIGHT (AMBER) FLASHES (SKYACTIV-G VIN Y) DIAGNOSTIC PROCEDURE

Step	Inspection	Results	Action
1	VERIFY DTC Perform the DTC inspection for the following modules. (See DTC INSPECTION .) PCM DSC HU/Control Module SAS control module TCM Are any DTCs displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [PCM (SKYACTIV-G VIN Y)] .) (See DTC TABLE [DSC HU/Control Module] .) (See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [TCM (GW6AX-EL)] .) (See DTC TABLE [SAS CONTROL MODULE (TWO-STEP DEPLOYMENT CONTROL SYSTEM - US/CANADA SPEC.)] .)
1		No	Go to the next step.
2	DETERMINE IF MALFUNCTION CAUSE IS BATTERY VOLTAGE DECREASE OR OTHER Start the engine and warm it up completely. Idle the engine. Access the PCM PID [BATT_SOC] using the M-MDS. (See PID/DATA MONITOR INSPECTION .) (See PID/DATA MONITOR TABLE [PCM (SKYACTIV-G VIN Y)] .) Is the [BATT_SOC] PID value above 68%?	Yes	Go to Step 4.
2		No	Recharge the battery, then go to the next step. (See BATTERY RECHARGING .)
3	INSPECT BATTERY FOR MALFUNCTION Inspect the applicable part. (See BATTERY INSPECTION .) Is the part normal?	Yes	Go to the next step.
3		No	Repair or replace the malfunctioning location and perform the repair completion verification. (See BATTERY REMOVAL/INSTALLATION .)
4	INSPECT GENERATOR FOR MALFUNCTION Inspect the applicable part. (See GENERATOR INSPECTION .) Is the part normal?	Yes	Go to the next step.
4		No	Repair or replace the malfunctioning location and perform the repair completion verification. (See GENERATOR REMOVAL/INSTALLATION .)
Repair completion verification 1	VERIFY THAT VEHICLE IS REPAIRED Install/connect the part removed/disconnected during the troubleshooting procedure. Has the malfunction symptom been eliminated?	Yes	Complete the symptom troubleshooting. (Explain contents of repair to customer)
Repair completion verification 1		No	Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error. (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW .) If the CAN communication is normal, perform the diagnosis from Step 1. If the malfunction recurs, go to the next step.
Repair completion verification 2	VERIFY IF MALFUNCTION IS CAUSED BY NOT PERFORMING PCM REPROGRAMMING Verify repair information and verify that there is a new calibration in the PCM. Is there a new calibration in the PCM?	Yes	Perform the PCM reprogramming and verify if the malfunction symptom was corrected. If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION .)
Repair completion verification 2		No	Replace the PCM. (See PCM REMOVAL/INSTALLATION .)
