DTC Troubleshooting
Step Action Yes No
1
Was “Engine and Emission Control System Check” performed?
Go to Step 2.
2
DTC recheck
1)Clear DTC. icon 
2)Set ignition “OFF”.
3)Check DTCs. icon 
Is DTC P0601, P0606, P0607, P060A, P060D, P0611, P061A, P061B, P061C, P061D or P1623 still detected?
Go to Step 3.
Check for intermittent trouble. icon 
3
ECM power supply circuit and ground circuit check
1)Check “B1”, “B2”, “B3”, “C1”, “C2” and “C3” circuits according to Step 2 of DTC P0562 / P0563:D16AA.
Is check result OK?
Replace ECM and recheck DTC. icon 
Repair or replace defective wire harness.
