DIAGNOSTICS PROCEDURE CHART

Step	Action	YES	NO
1	Warning light check Push engine switch to change ignition mode of keyless push start system to "ON". Do other indicator lights come ON?	Go to Step 2.	Go to Step 4.
2	DTC check Confirm that ignition mode of keyless push start system is in "OFF". Connect scan tool to DLC. Push engine switch to change ignition mode "ON". Check DTC. Is DTC U0073 detected?	Go to "TROUBLESHOOTING FOR COMMUNICATION BUS OFF ":	Go to Step 3.
