DTC Confirmation Procedure

WARNING: This page is about a different car, the 2012 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Always drive vehicle at a safe speed.
NOTE: If "DTC Confirmation Procedure" has been previously performed, always turn ignition switch OFF and wait at least 10 seconds before performing the next test.

After the repair, perform the following procedure to confirm the malfunction is eliminated.

WITH CONSULT

  1. Start the engine and select "DATA MONITOR" mode for "TRANSMISSION" with CONSULT.
  2. Make sure that "ATF TEMP 1" is within the following range.

    ATF TEMP 1: 20 - 140°C (68 - 284°F) 

    If out of range, drive vehicle to warm ATF or stop engine to cool ATF.

  3. Select "1ST GR FNCTN P0731" of "DTC & SRT CONFIRMATION" mode for "TRANSMISSION" with CONSULT.
  4. Drive vehicle and maintain the following conditions.

    With manual mode:

    MANU MODE SW: ON 

    GEAR: "1" position 

    ACCELE POSI: 0.6/8 or more 

    VEHICLE SPEED: 10 km/h (6 MPH) or more 

    ENGINE SPEED: INPUT SPEED - 50 RPM or more 

    INPUT SPEED: 300 RPM or more 

    Without manual mode:

    SLCT LVR POSI: "1" position 

    GEAR: "1" position

    VEHICLE SPEED: 10 km/h (6 MPH) or more

    INPUT SPEED: 300 RPM or more 

  5. Keep the current driving status for at least 5 consecutive seconds if CONSULT screen changes from "OUT OF CONDITION" to "TESTING".
    CAUTION: If "TESTING" does not appear on CONSULT for a long time, select "SELF-DIAG RESULTS". In case a 1st trip DTC other than P0731 is shown, refer to "CONSULT FUNCTION (TRANSMISSION) ".

    If "COMPLETED RESULT NG" is detected, go to "DIAGNOSIS PROCEDURE ".

    If "STOP VEHICLE" is detected, go to the following step.

  6. Stop vehicle.
  7. Drive vehicle in "D" position allowing it to shift from 1GR to 5GR and check shift timing and shift shock.
    • Touch "OK" to complete the inspection when normally shifted from the 1GR to 5GR.
    • Touch "NG" when an unusual shift shock, etc. occurs in spite of shifting from the 1GR to 5GR. Go to "CHECK BEFORE ENGINE IS STARTED ".
    • Perform "CONSULT FUNCTION (TRANSMISSION) " when not shifted from the 1GR to 5GR. (Neither "OK" nor "NG" are indicated.)
