FAIL-SAFE CONTROL
Switches to fail-safe control when malfunction is detected in encoder signal that detects up/down speed and direction of door glass. Switches to fail-safe control when a signal that is out of the specified value is detected between the fully closed position and the actual position of the glass.
| Malfunction | Malfunction condition |
|---|---|
| Pulse sensor malfunction | When one pulse signal that is the specified value or more is detected continuously for the specified time or more, while door glass is being operated UP or DOWN. |
| Both pulse sensors malfunction | When both pulse signals are not detected continuously for the specified time or more, while door glass is being operated UP or DOWN. |
| Pulse direction malfunction | When a pulse signal indicating that window is moving in the opposite direction against the power window motor is detected for the specified value or more, while door glass is being operated UP or DOWN. |
| Glass recognition position malfunction 1 | When the actual door glass position that is out of specified value is detected compared to the door glass fully closed position memorized in module, while door glass is being operated UP or DOWN. |
| Glass recognition position malfunction 2 | When pulse count that is out of the door glass full stroke value or more is detected, while door glass is being operated UP or DOWN. |
MALFUNCTION CONDITION CHART
If fail-safe control, the system changes to a non-initialized condition and the following function do not operate.
- Auto-up operation
- Anti-pinch function
- Door key cylinder switch power window function
When fail-safe control is activated, perform initialization procedure to recover. If a malfunction is detected in power window switch or more, fail-safe control is activated again.

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 AIRBAG" and "SEAT BELT" of this Service Information.
| 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 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. |
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
| WARNING | When 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 3 minutes before performing any service. |
Precaution Necessary for Steering Wheel Rotation after Battery Disconnect
Note. Before removing and installing any control units, first turn the push-button ignition switch to the LOCK position, then disconnect both battery cables. After finishing work, confirm that all control unit connectors are connected properly, then re-connect both battery cables. Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work. If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.
This vehicle is equipped with a push-button ignition switch and a steering lock unit.
If the battery is disconnected or discharged, the steering wheel will lock and cannot be turned.
If turning the steering wheel is required with the battery disconnected or discharged, follow the procedure below before starting the repair operation.
