Vehicle Damage Warnings

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 collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.

Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.

WARNING:
^ To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
^ Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see the SRS section.
^ Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors.

Precaution for On Board Diagnosis (OBD) System of CVT and Engine
The ECM has 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 EVAP system or fuel injection system, etc.
^ Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM and ECM before returning the vehicle to the customer.

Precaution for TCM and CVT Assembly Replacement
When replacing CVT assembly or TCM, refer to the pattern table below and erase the EEPROM in the TCM if necessary.

CAUTION:
^ Check if new data (Unit ID) are entered correctly after replacing CVT assembly and erasing data in TCM. (Connect CONSULT-III, and then turn ignition switch OFF.)
^ "TCM POWER SUPPLY [P1701]" may be indicated soon after replacing TCM or CVT assembly (after erasing the memory). Restart the self-diagnosis after erasing the self-diagnosis result. Check that no error is detected.

EEPROM ERASING PATTERNS








METHOD FOR ERASING THE EEPROM IN THE TCM
1. Connect CONSULT-III to data link connector.
2. Turn ignition switch ON. Confirm that CONSULT-III is turned ON.
3. Move selector lever to "R" position.
4. Select "SELF-DIAG RESULTS" mode for "TRANSMISSION" with CONSULT-III.
5. Press the brake pedal and turn the brake switch ON.
6. Press the accelerator pedal (0.5/8 - 4/8 throttle) not to exceed the half, and hold it in the half or less open position. (This will set the closed throttle position signal to OFF and the wide open throttle position signal to OFF.)
7. Touch "ERASE" on CONSULT-III, and then touch "YES".
8. Wait 3 seconds and then release the accelerator pedal.
9. Turn ignition switch OFF.

METHOD FOR WRITING DATA FROM THE ROM ASSEMBLY IN THE TRANSAXLE
In the following procedure, the TCM reads data from the ROM assembly and writes it to the EEPROM in the TCM.
1. Erase the EEPROM in the TCM.
2. Move selector lever to "P" position.
3. Turn ignition switch ON.

CHECK METHOD
^ Standard: About 2 seconds after the ignition switch ON, the CVT indicator lamp lights up for 2 seconds.
^ Non-standard: Even after the ignition switch ON, the CVT indicator lamp does not light up after 2 seconds or illuminates immediately

CAUTION: Perform in the "P" or "N" position.

Action for Non-standard
^ Replace the CVT assembly.
^ Replace the TCM.

Removal and Installation Procedure for CVT Unit Connector

REMOVAL





Rotate bayonet ring counterclockwise, pull out CVT unit harness connector upward to disconnect it.

INSTALLATION





1. Align CVT unit harness connector terminal body marking with bayonet ring marking, insert CVT unit harness connector, and then rotate bayonet ring clockwise.





2. Rotate bayonet ring clockwise until CVT unit harness connector terminal body marking is aligned with the bayonet ring marking (linear slit) as shown





CAUTION:
^ Securely align CVT unit harness connector terminal body marking with bayonet ring marking (linear slit). Do not make a half fit condition as shown.
^ Do not mistake the bayonet ring marking (linear slit) for other dent portion.

Precaution

NOTE: If any malfunction occurs in the REOF09B model transaxle, replace the entire transaxle assembly.





^ Before connecting or disconnecting the TCM harness connector, turn ignition switch OFF and disconnect the battery cable from the negative terminal. Because battery voltage is applied to TCM even if ignition switch is turned OFF.

^ When connecting or disconnecting pin connectors into or from TCM, take care not to damage pin terminals (bend or break).
When connecting pin connectors make sure that there are not any bends or breaks on TCM pin terminal.

^ Before replacing TCM, perform TCM input/output signal inspection and make sure whether TCM functions properly or not. CVT-41, "TCM Input/Output Signal Reference Value". TCM Input/Output Signal Reference Value

^ After performing each TROUBLE DIAGNOSIS, perform "DTC Confirmation Procedure".
If the repair is completed the DTC should not be displayed in the "DTC Confirmation Procedure".
^ Always use the specified brand of CVT fluid.
^ Use lint-free paper, not cloth rags, during work.
^ After replacing the CVT fluid, dispose of the waste oil using the methods prescribed by law, ordinance, etc.

Service Notice or Precaution

CVT FLUID COOLER SERVICE
If CVT fluid contains friction material (clutches, brakes, etc.), or if an CVT is replaced, inspect and clean the CVT fluid cooler mounted in the radiator or replace the radiator. Flush cooler lines using cleaning solvent and compressed air after repair.

OBD-II SELF-DIAGNOSIS
^ CVT self-diagnosis is performed by the TCM in combination with the ECM. The results can be read through the blinking pattern of the malfunction indicator lamp (MIL). Refer to the table on CVT-44, "CONSULT-III Function (TRANSMISSION)" for the indicator used to display each self-diagnostic result. Consult-III Function (Transmission)
^ The self-diagnostic results indicated by the MIL are automatically stored in both the ECM and TCM memories. Always perform the procedure on CVT-24, "OBD-II Diagnostic Trouble Code (DTC)" to complete the repair and avoid unnecessary blinking of the MIL. Reading and Clearing Diagnostic Trouble Codes
^ Certain systems and components, especially those related to OBD, may use the new style slide-locking type harness connector.
