Diagnostic Procedure

WARNING: This page is about a different car, the 2004 Nissan Quest. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK PNP SWITCH CIRCUIT 

    With CONSULT-II 

    1. Turn ignition switch "ON". (Do not start engine.)
    2. Select "DATA MONITOR" mode for "TRANSMISSION" with CONSULT-II.
    3. Move selector lever to "P", "R""N""D" and "L" position and check the value of "PNP SW A""PNP SW B""PNP SW C""PNP SW PA" and "PNP SW PN".

    7. If OK, check harness for short-circuit to ground or power source.

    OK or NG 

    1. OK: GO TO 3.
    2. NG: Check the following. If any items are damaged, repair or replace damaged parts.
      • Harness for short or open between ignition switch and PNP switch
      • Ignition switch and fuse

        Refer to POWER DISTRIBUTION .

  3. CHECK HARNESS BETWEEN TCM AND PNP SWITCH 
    1. Turn ignition switch "OFF".
    2. Disconnect the TCM connector and PNP switch connector.
    3. Check continuity between TCM connector terminals 24, 31, 32, 43 and ground.

    4. If OK, check the following.
      • Harness for short-circuit to ground or power source.
      • Open or short-circuit in the harness between combination meter and TCM.

    OK or NG 

    1. OK: GO TO  5.
    2. NG: GO TO 4.
  4. DETECT MALFUNCTIONING ITEM 

    Check the following.

    • Open or short-circuit in the harness between TCM and PNP switch A, B, C, PA.
    • Open or short-circuit in the harness for ground of PNP switch.
    • PNP switch. Refer to "COMPONENT INSPECTION ".

    OK or NG 

    1. OK: GO TO  6.
    2. NG: Repair or replace damaged parts.
  5. CHECK DTC 

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

    OK or NG 

    1. OK: INSPECTION END 
    2. NG: GO TO 6.
  6. CHECK TCM 
    1. Check TCM input/output signal.
    2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.

    OK or NG 

    1. OK: INSPECTION END 
    2. NG: Repair or replace damaged parts.
