DTC No. 13 / No. 14: Release Signal Error from Steering Lock Unit / Steering Lock Unit MalfunctionS7RS0BA504018
DTC Detecting Condition and Trouble Area
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.

DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure
1) Clear DTC referring to “DTC Clearance”.
2) Turn ignition knob switch pushing ignition knob switch.
3) Push request switch of each door.
4) Check DTC referring to “DTC Check”.
Troubleshooting
Substitute a known-good keyless start control module and recheck. 3
Steering lock unit power supply voltage check
1) Connect connector to keyl ess start control module.
2) Measure voltage between “G22-3” terminal of steering lock unit connector and vehicle body ground.
Is voltage 4 – 6 V? Replace steering lock
unit.
Substitute a known-
good keyless start
control module and
recheck.
