DTC Confirmation Procedure
WARNING:
If you do not select a suitable route and take proper precautions when performing a road test, an accident can occur.
•Select a level road with no traffic to minimize the risk of accident.
•Perform the test extremely carefully.
•Perform the road test with 2 persons, a driver and a tester.
NOTE:
Check that the following condition is satisfied in this procedure.
•11 V < Battery voltage < 15 V
1)Start engine and drive vehicle.
DTC Troubleshooting
Step Action Yes No

Go to Step 2.
2
DTC check
Is there any CAN-DTC detected?
Go to troubleshooting for CAN-DTC. icon 
Go to Step 3.
3
DTC check
1)Check ECM for DTC.
Is there any DTC(s) detected?
Go to troubleshooting for applicable DTC.
Replace TCM and recheck DTC. icon
