DTC Confirmation ProcedureEBS00K4F
CAUTION:
Always drive at a safe speed.
NOTE:
●If DTC P0011 is displayed with DTC P1111, first perform trouble diagnosis for “DTC P1111”. See
EC-272, "
DTC P1111 IVT CONTROL SOLENOID VALVE" .
●If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch “OFF” and
wait at least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is between 10V and 16V at
idle.
WITH CONSULT-II
1. Turn ignition switch “ON” and select ″DATA MONITOR″ mode
with CONSULT-II.
2. Start engine and warm it up to the normal operating tempera-
ture.
3. Maintain the following conditions for at least 20 consecutive sec-
onds.
4. Stop vehicle with engine running and let engine idle for 10 seconds.
5. If 1st trip DTC is detected, go to EC-121, "

If 1st trip DTC is not detected, go to next step.
6. Maintain the following conditions for at least 10 consecutive seconds.
7. If 1st trip DTC is detected, go to EC-121, "
Diagnostic Procedure" .
