DTC Confirmation ProcedureEBS01KFW
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
WITH CONSULT-II
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Wait at least 5 seconds.
4. If DTC is detected, go toEC-145, "
Diagnostic Procedure".
WITHOUT CONSULT-II
1. Turn ignition switch ON and wait at least 5 seconds.
2. Turn ignition switch OFF, wait at least 10 seconds and then turn ON.
3. Perform Diagnostic Test Mode II (Self-diagnostic results) with ECM.
4. If DTC is detected, go toEC-145, "
Diagnostic Procedure".

Overall Function CheckEBS01KG5
Use this procedure to check the overall function of the turbocharger. During this check, a DTC might not be
confirmed.
1. Start engine and let it idle.
2. Make sure that turbocharger control actuator (1) rod moves
slightly when engine is started.
3. If NG, go toEC-150, "
