DTC Confirmation ProcedureNBS005BC
CAUTION:
Always drive at a safe speed.
NOTE:
If DTC P0011 or P0021 is displayed with DTC P0075, P0081, P1140 or P1145, first perform the trou-
ble diagnosis for EC-899, "
DTC P0075, P0081 IVT CONTROL SOLENOID VALVE" or EC-1203, "DTC
P1140, P1145 IVT CONTROL POSITION SENSOR" .
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.
PROCEDURE FOR MALFUNCTION A
With CONSULT-II
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Maintain the following conditions for at least 10 consecutive sec-
onds.
4. Maintain the following conditions for at least 20 consecutive sec-
onds.
5. If the 1st trip DTC is detected, go to EC-877, "
Diagnostic Procedure" .
With GST
Follow the procedure “With CONSULT-II” above.
PROCEDURE FOR MALFUNCTION B
With CONSULT-II
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Maintain the following conditions for at least 10 consecutive sec-
onds.
4. If the 1st trip DTC is detected, go to EC-877, "
Diagnostic Proce-
dure" .
With GST
Follow the procedure “With CONSULT-II” above.
