Diagnostic Procedure

WARNING: This page is about a different car, the 2005 Nissan Quest. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK FLUID TEMPERATURE SENSOR SIGNAL 

    With CONSULT-II 

    1. Start engine.
    2. Select "A/T" with "DATA MONITOR" mode in CONSULT-II.

    3. Turn ignition switch "OFF".
    4. Disconnect the TCM connector.
    5. Check if there is continuity between the connector terminal and ground.

    OK or NG

    • OK : GO TO  6.
    • NG : GO TO 2.
  2. CHECK FLUID TEMPERATURE SENSOR CIRCUIT 
    1. Turn ignition switch "OFF".
    2. Disconnect the TCM connector.
    3. Check resistance between terminals 41 and 42.

    4. Check if there is continuity between the connector terminal and ground.

    OK or NG

    • OK : GO TO  6.
    • NG : GO TO 3.
  3. CHECK TERMINAL CORD ASSEMBLY WITH A/T FLUID TEMPERATURE SENSOR 
    1. Turn ignition switch "OFF".
    2. Disconnect terminal cord assembly harness connector.
    3. Check resistance between terminals 4 and 8.

    4. Reinstall any part removed.

    OK or NG

    • OK : GO TO 4.
    • NG : GO TO  5.
  4. CHECK HARNESS BETWEEN TCM AND TERMINAL CORD ASSEMBLY 

    Check the following.

    • Open or short-circuit in the harness between TCM and terminal cord assembly.

    OK or NG

    • OK : GO TO 6.
    • NG : Repair or replace damaged parts.
  5. CHECK A/T FLUID TEMPERATURE SENSOR 
    1. Remove side cover. Refer to SIDE COVER .
    2. Disconnect A/T fluid temperature sensor.
    3. Check resistance between terminals 4 and 8.

    OK or NG

    • OK : GO TO 6.
    • NG : Repair or replace transmission wire. Refer to TRANSMISSION WIRE .
  6. CHECK DTC 

    Perform "DTC Confirmation Procedure". Refer to DTC CONFIRMATION PROCEDURE .

    OK or NG

    • OK : INSPECTION END 
    • NG : GO TO 7.
  7. CHECK TCM 
    1. Check TCM input/output signal. Refer to TCM INPUT/OUTPUT SIGNAL REFERENCE VALUES .
    2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.

    OK or NG

    • OK : INSPECTION END 
    • NG : Repair or replace damaged parts.
