How to Erase DTC

WARNING: This page is about a different car, the 2004 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.

WITH CONSULT-II

The emission related diagnostic information in the ECM can be erased by selecting "ERASE" in the "SELF-DIAG RESULTS" mode with CONSULT-II.

If DTCs are displayed for both ECM and TCM (Transmission control module), they need to be erased individually from the ECM and TCM (Transmission control module).

NOTE: If the DTC is not for AT related items (see "INDEX FOR DTC "), skip steps 2 through 4.

If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait at least 10 seconds and then turn it ON (engine stopped) again.
Turn CONSULT-II ON and touch "AT".
Touch "SELF-DIAG RESULTS".
Touch "ERASE". [The DTC in the TCM (Transmission control module) will be erased.] Then touch "BACK" twice.
Touch "ENGINE".
Touch "SELF-DIAG RESULTS".
Touch "ERASE". (The DTC in the ECM will be erased.)

WITH GST

The emission related diagnostic information in the ECM can be erased by selecting Mode 4 with GST.

NOTE: If the DTC is not for AT related items (see "INDEX FOR DTC "), skip step 2.

If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait at least 10 seconds and then turn it ON (engine stopped) again.
Perform DIAGNOSTIC PROCEDURE WITHOUT CONSULT-II for RE4F03B transmission or DIAGNOSTIC PROCEDURE WITHOUT CONSULT-II for RE4F04B transmission. (The engine warm-up step can be skipped when performing the diagnosis only to erase the DTC.)
Select Mode 4 with GST (Generic Scan Tool).

NO TOOLS

If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once.
Wait at least 10 seconds and then turn it ON (engine stopped) again.
Change the diagnostic test mode from Mode II to Mode I by depressing the accelerator pedal. Refer to "HOW TO SWITCH DIAGNOSTIC TEST ".

If the battery is disconnected, the emission-related diagnostic information will be lost within 24 hours.
The following data are cleared when the ECM memory is erased.
- Diagnostic trouble codes
- 1st trip diagnostic trouble codes
- Freeze frame data
- 1st trip freeze frame data
- System readiness test (SRT) codes
- Test values
- 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.
