NR Series ENGINE CONTROL  SFI SYSTEM  DTC CHECK / CLEAR  


NOTICE:

When the diagnosis system is changed from normal mode to check mode or vice versa, all DTCs and Freeze Frame Data recorded in normal mode are cleared. Before changing modes, always check and make a note of DTCs and Freeze Frame Data.


HINT:
·

DTCs which are stored in the ECM can be displayed on the GTS. The GTS can display the confirmed, pending and permanent DTCs.

·

If a malfunction is detected during the current driving cycle, confirmed and permanent DTCs are stored.

·

Some DTCs are not stored if the ECM does not detect the same malfunction again during a second consecutive driving cycle. However, such malfunctions, detected on only one occasion, are stored as pending DTCs.

·

Confirmed and pending DTCs can be cleared by using the GTS or by disconnecting the cable from the negative (-) battery terminal. However, permanent DTCs cannot be cleared using either of these two methods.

·

After clearing current DTCs using the GTS (or by disconnecting the cable from the negative (-) battery terminal), permanent DTCs can be cleared when the universal trip is performed and then the system is determined to be normal for the relevant DTCs. The driving pattern to obtain a normal judgment is described under the "Confirmation Driving Pattern" for the respective DTC.

To clear permanent DTCs, all of the following conditions must be are met:

-

There is a history that universal trip driving was performed.

-

The vehicle has been judged as normal for 2 trips. (Normal judgment does not have to be performed in 2 consecutive trip, but normal judgment should occur in the latest trip.) (not for misfire and fuel system DTCs)

-

No malfunctions are detected.

CLEAR PERMANENT DTC


OUTLINE

After clearing current DTCs using the GTS (or by disconnecting the cable from the negative (-) battery terminal), permanent DTCs can be cleared when the universal trip is performed and then the system is determined to be normal for the relevant DTCs. The driving pattern to obtain a normal judgment is described under the "Confirmation Driving Pattern" for the respective DTC.

To clear permanent DTCs, all of the following conditions must be are met:

-

There is a history that universal trip driving was performed.

-

The vehicle has been judged as normal for 2 trips. (Normal judgment does not have to be performed in 2 consecutive trip, but normal judgment should occur in the latest trip.) (not for misfire and fuel system DTCs)

-

No malfunctions are detected.

b.

Turn the ignition switch to ON.


c.

Turn the GTS on.


d.

Enter the following menus: Powertrain / Engine / Trouble Codes.

Powertrain > Engine > Trouble Codes
