Nissan Murano: Transaxle & Transmission :: Cvt: Re0f10j / Precaution. Precautions

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collisions.

Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” sections of this Service Manual.

WARNING:

Always observe the following items for preventing accidental activation:

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

Always observe the following items for preventing accidental activation:

When performing the procedure after removing cowl top cover, cover the lower end of windshield with urethane, etc to prevent damage to windshield.

CAUTION:

• To replace TCM, refer to Description.

• To replace transaxle assembly, refer to Description.

• Turn ignition switch OFF and disconnect the battery cable from the negative terminal before connecting or disconnecting the CVT assembly harness connector. Because battery voltage is applied to TCM even if ignition switch is turned OFF.

  

• When connecting or disconnecting pin connectors into or from TCM, do not damage pin terminals (bend or break).

  

  Check that there are not any bends or breaks on TCM pin terminal, when connecting pin connectors.

• Perform TCM input/output signal inspection and check whether TCM functions normally or not before replacing TCM. Refer to Reference Value.

  

• Perform “DTC (Diagnostic Trouble Code) CONFIRMATION PROCEDURE”.

  

  If the repair is completed DTC should not be displayed in the “DTC CONFIRMATION PROCEDURE”.

• Always use the specified brand of CVT fluid. Refer to Fluids and Lubricants.

• Use lint-free paper not cloth rags during work.

• Dispose of the waste oil using the methods prescribed by law, ordinance, etc. after replacing the CVT fluid.

The TCM and ECM have an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to warn the driver of a malfunction causing emission deterioration.

CAUTION:

• Be sure to turn the ignition switch OFF and disconnect the battery cable from the negative terminal before any repair or inspection work. The open/short circuit of related switches, sensors, solenoid valves, etc. will cause the MIL to light up.

• Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will cause the MIL to light up due to an open circuit. (Be sure the connector is free from water, grease, dirt, bent terminals, etc.)

• Be sure to route and secure the harnesses properly after work. Interference of the harness with a bracket, etc. may cause the MIL to light up due to a short circuit.

• Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube may cause the MIL to light up due to a malfunction of the EGR system or fuel injection system, etc.

• Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM and ECM before returning the Nissan Murano vehicle to the customer.

REMOVAL

• Rotate bayonet ring (1) counterclockwise. Pull out CVT unit harness connector (2) upward and remove it.

  

INSTALLATION

1. Align marking (A) on CVT unit harness connector terminal with marking (B) on bayonet ring. Insert CVT unit harness connector.

   

2. Rotate bayonet ring clockwise.

3. Rotate bayonet ring clockwise until marking (A) on CVT unit harness connector terminal body is aligned with the slit (B) on bayonet ring as shown in the figure (correctly fitting condition).

   

   CAUTION:

   • Securely align marking (A) on CVT unit harness connector terminal body with bayonet ring slit (B). Then, be careful not to make a half fit condition as shown in the figure.

     

   • Never mistake the slit of bayonet ring for other dent portion.
