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. Information necessary to service the system safely is included in the " SRS AIRBAG " and " SEAT BELTS SRS AIRBAG " articles of this Service Information.

WARNINGAlways observe the following items to prevent accidental activation. To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that 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 " SRS AIRBAG ". Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Information. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. The vehicle may be equipped with a passenger air bag deactivation switch which can be operated by the customer. When the passenger air bag is switched OFF, the passenger air bag is disabled and will not inflate. When the passenger air bag is switched ON, the passenger air bag is enabled and could inflate for certain types of collision. After SRS maintenance or repair, make sure the passenger air bag deactivation switch is in the same position (ON or OFF) as when the vehicle arrived for service.

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

WARNINGWhen working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Ignition ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the battery and wait at least three minutes before performing any service.

BELT & PULLEY

Mechanism

It is composed of a pair of pulleys (the groove width is changed freely in the axial direction) and the steel belt (the steel plates are placed continuously and the belt is guided with the multilayer steel rings on both sides). The groove width changes according to wrapping radius of steel belt and pulley from low status to overdrive status continuously with non-step. It is controlled with the oil pressures of primary pulley and secondary pulley.

Steel belt

It is composed of multiple steel plates (A) and two steel rings (B) stacked to a several number. The feature of this steel belt transmits power with compression of the steel plate in contrast with transmission of power in pulling with a rubber belt. Friction force is required with the pulley slope to transmit power from the steel plate. The force is generated with the following mechanism

Oil pressure applies to the secondary pulley to nip the plate. ==> The plate is pushed and extended outward. ==> The steel ring shows withstands. ==> Pulling force is generated on the steel ring. ==> The plate of the primary pulley is nipped between the pulley. ==> Friction force is generated between the steel belt and the pulley.

Scheme 94

Scheme 94: BELT & PULLEY

Therefore, responsibilities are divided by the steel plate that transmits the power with compression and the steel ring that maintains necessary friction force. In this way, the tension of the steel ring is distributed on the entire surface and stress variation is limited, resulting in good durability.

Pulley

The primary pulley (input shaft side) and the secondary pulley (output shaft side) have the shaft with slope (fixed cone surface), movable sheave (movable cone surface that can move in the axial direction) and oil pressure chamber at the back of the movable sheave.

Scheme 95

Scheme 95

Pulley gear shifting operation

Scheme 96

Scheme 96
  1. Pulley gear shifting operation The movable sheave slides on the shaft to change the groove width of the pulley. Input signals of engine load (accelerator pedal opening), engine revolution and gear ratio (vehicle speed) change the operation pressures of the primary pulley and the secondary pulley, and controls the pulley groove width. Along with change of the pulley groove width, the belt contact radius is changed. This allows continuous and stepless gear shifting from low to overdrive. "The contact radius ratio of each pulley in contact with the belt x auxiliary gearbox gear ratio" is the gear ratio.

AUXILIARY GEARBOX MECHANISM

1st, 2nd and reverse gears are changed with the planetary gear mechanism.

TRANSAXLE: Oil Pressure System

Oil pressure required for operation of the transaxle transmission mechanism is generated by oil pump, oil pressure control valve, solenoid valve, etc.

CVT CONTROL SYSTEM: Protection Control

The TCM becomes the protection control status temporarily to protect the safety when the safety of TCM and transmission is lost. It automatically returns to the normal status if the safety is secured.

The TCM has the following protection control.

CONTROL FOR WHEEL SPIN

ControlWhen a wheel spin is detected, the engine output and gear ratio are limited and the line pressure is increased. At the 1GR, the clutch pressure is increased.
Vehicle behavior in controlIf the accelerator is kept depressing during wheel spin, the engine revolution and vehicle speed are limited to a certain degree. From the 1GR, upshift to a certain gear ratio is only allowed.
Normal return conditionWheel spin convergence returns the control to the normal control.

REVERSE PROHIBIT CONTROL

ControlThe reverse brake is controlled to avoid becoming engaged when the selector lever is set in "R" position while driving in forward direction at more than the specified speed.
Vehicle behavior in controlIf the selector lever is put at "R" position when driving with the forward gear, the gear becomes neutral, not reverse.
Normal return conditionThe control returns to normal control when the vehicle is driven at low speeds. (The reverse brake becomes engaged.)

CONSULT DATA MONITOR STANDARD VALUE

  1. In CONSULT, electric shift timing or lock-up timing, i.e. operation timing of each solenoid valve, is displayed. Therefore, if there is an obvious difference between the shift timing estimated from a shift shock (or engine speed variations) and that shown on the CONSULT, the mechanism parts (including the hydraulic circuit) excluding the solenoids and sensors may be malfunctioning. In this case, check the mechanical parts following the appropriate diagnosis procedure.
  2. Shift point (gear position) displayed on CONSULT slightly differs from shift pattern described in Service Information. This is due to the following reasons.
  1. Actual shift pattern may vary slightly within specified tolerances.
  2. While shift pattern described in Service Information indicates start of each shift, CONSULT shows gear position at end of shift.
  3. The solenoid display (ON/OFF) on CONSULT is changed at the start of gear shifting. In contrast, the gear position display is changed at the time when gear shifting calculated in the control unit is completed.

Fail-safe

TCM has a fail-safe mode. The mode functions so that operation can be continued even if the signal circuit of the main electronically controlled input/output parts is damaged.

If the vehicle shows following behaviors including "poor acceleration", a malfunction of the applicable system is detected by TCM and the vehicle may be in a fail-safe mode. At this time, check the DTC code and perform inspection and repair according to the malfunction diagnosis procedures.

Protection Control

The TCM becomes the protection control status temporarily to protect the safety when the safety of TCM and transmission is lost. It automatically returns to the normal status if the safety is secured.

The TCM has the following protection control.

ControlWhen a wheel spin is detected, the engine output and gear ratio are limited and the line pressure is increased. At the 1GR, the clutch pressure is increased.
Vehicle behavior in controlIf the accelerator is kept depressing during wheel spin, the engine revolution and vehicle speed are limited to a certain degree. From the 1GR, upshift to a certain gear ratio is only allowed.
Normal return conditionWheel spin convergence returns the control to the normal control.
ControlThe reverse brake is controlled to avoid becoming engaged when the selector lever is set in "R" position while driving in forward direction at more than the specified speed.
Vehicle behavior in controlIf the selector lever is put at "R" position when driving with the forward gear, the gear becomes neutral, not reverse.
Normal return conditionThe control returns to normal control when the vehicle is driven at low speeds. (The reverse brake becomes engaged.)

Scheme 104: Inspection
  1. Turn ON the ignition switch with the shift selector in the "P" position.
  2. Press the shift selector handle button with the brake pedal depressed, and confirm that the shift selector can be moved from the "P" position. Also confirm that shift selector will not move from the "P" position without depressing the brake pedal.
  3. Move the shift selector and check for "excessive effort," "sticking," "noise" or "rattle".
  4. Confirm that shift selector stops at each position with the feel of engagement when it is moved through all the positions. Check whether or not the actual position the shift selector is in matches the position shown by the transaxle body.
  5. The method of operating the shift selector to individual positions correctly should be as shown. (A): Press shift selector button to operate shift selector, while depressing the brake pedal. (B): Press shift selector button to operate shift selector. (C): Shift selector can be operated without pressing shift selector button.
  6. When the shift selector handle button is pressed without applying forward/backward force to the shift selector at "P", "R", "N" and "D" positions, there should be no "sticking" of the button.
