2. Select Mode 4 with GST (Generic Scan Tool).
The emission-related diagnostic information can be erased by selecting Mode 4 with GST (Generic Scan Tool).
How to Erase DTC (No Tools)NCEC0031S06031. If the ignition switch stays ªONº after repair work, be sure to turn ignition switch ªOFFº once. Wait at least
9 seconds and then turn it ªONº again.
2. Change the diagnostic test mode from Mode II to Mode I by using the data link connector. (See EC-QG-
48.)
The emission-related diagnostic information can be erased by changing the diagnostic test mode from Diag-
nostic Test Mode II to Mode I by using the data link connector. (Refer to EC-QG-48.)
NOTE:
IIf the battery is disconnected, the emission-related diagnostic information will be lost after approx.
24 hours.
IErasing the emission-related diagnostic information using CONSULT-II or GST is easier and
quicker than switching the mode using the data link connector.
IThe following data are cleared when the ECM memory is erased.
1) Diagnostic trouble codes
2) 1st trip diagnostic trouble codes
3) Freeze frame data
4) 1st trip freeze frame data
5) System readiness test (SRT) codes
6) Test values
7) Distance traveled while MI is activated
8) Others
Actual work procedures are explained using a DTC as an example. Be careful so that not only the DTC, but
all of the data listed above, are cleared from the ECM memory during work procedures.
Malfunction Indicator (MI)
NATS (Nissan Anti-Theft System)
IIf the security indicator lights up with the ignition switch in the ªONº position or ªNATS MALFUNC-
TIONº is displayed on ªSELF-DIAG RESULTSº screen, perform self-diagnostic results mode with
CONSULT-II using NATS program card. Refer to ªNATS (Nissan Anti-Theft System)º in EL section.
IConfirm no self-diagnostic results of NATS is displayed before touching ªERASEº in ªSELF-DIAG
RESULTSº mode with CONSULT-II.
IWhen replacing ECM, initialization of NATS system and registration of all NATS ignition key IDs
must be carried out with CONSULT-II using NATS program card.
Therefore, be sure to receive all keys from vehicle owner. Regarding the procedures of NATS ini-
tialization and NATS ignition key ID registration, refer to CONSULT-II operation manual, NATS.

How to Erase DTC (No Tools)NCEC0031S0603NOTE:
If the diagnostic trouble code is not for CVT related items (see EC-SR-6), skip step 2.
1. If the ignition switch stays ªONº after repair work, be sure to turn ignition switch ªOFFº once. Wait at least
9 seconds and then turn it ªONº again.
2. Perform ªSELF-DIAGNOSTIC PROCEDURE (Without CONSULT-II)º in AT section titled ªTROUBLE
DIAGNOSISº, ªSelf-diagnosisº. (The engine warm-up step can be skipped when performing the diagnosis
only to erase the DTC.)
3. Change the diagnostic test mode from Mode II to Mode I by using the data link connector. (See EC-SR-
61.)
The emission-related diagnostic information can be erased by changing the diagnostic test mode from Diag-
nostic Test Mode II to Mode I by using the data link connector. (Refer to EC-SR-61.)
