How to Erase DTC (No Tools)

WARNING: This page is about a different variant/trim than selected.
NOTE: If the DTC is not for A/T related items (see INDEX FOR DTC ), skip step 2.
  1. 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.

  2. Perform HOW TO ERASE DTC (NO TOOLS) in Automatic Transaxle - VQ35DE - Altima. (The DTC in the TCM will be erased.)
  3. Change the diagnostic test mode from Mode II to Mode I by depressing the accelerator pedal. Refer to "HOW TO SWITCH DIAGNOSTIC TEST MODE ".
    • 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.
