DTC Confirmation Procedure1) Clear DTC referring to “DTC Clearance”.
2) Turn ignition knob switch pushing ignition knob switch.
3) Check DTC referring to “DTC Check”.
Troubleshooting
Replace steering lock unit and recheck.
NOTE
DTC No. 13 is also set is such case where the keyless start control module which was used in another
vehicle is installed, the remote controller ID code is registered in it but the ignition key transponder
code is not registered in ECM. Therefore, when DTC No. 13 is detected, register the ignition key
transponder code in ECM before replacing the steering lock unit.
