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 disconnecting the battery terminal, pay attention to the following.

• Always use a 12V battery as power source.

• Never disconnect battery terminal while engine is running.

• When removing the 12V battery terminal, turn OFF the ignition switch and wait at least 30 seconds.

  

• For Nissan Murano vehicles with the engine listed below, remove the battery terminal after a lapse of the specified time:

  BR08DE	: 4 minutes	V9X engine	: 4 minutes
  D4D engine	: 20 minutes	YD25DDTi	: 2 minutes
  HR09DET	: 12 minutes	YS23DDT	: 4 minutes
  HRA2DDT	: 12 minutes	YS23DDTT	: 4 minutes
  K9K engine	: 4 minutes	ZD30DDTi	: 60 seconds
  M9R engine	: 4 minutes	ZD30DDTT	: 60 seconds
  R9M engine	: 4 minutes

  NOTE:

  ECU may be active for several tens of seconds after the ignition switch is turned OFF. If the battery terminal is removed before ECU stops, then a DTC detection error or ECU data corruption may occur.

• After high-load driving, if the Nissan Murano vehicle is equipped with the V9X engine, turn the ignition switch OFF and wait for at least 15 minutes to remove the battery terminal.

  NOTE:

  • Turbocharger cooling pump may operate in a few minutes after the ignition switch is turned OFF.

  • Example of high-load driving

    • Driving for 30 minutes or more at 140 km/h (86 MPH) or more.

    • Driving for 30 minutes or more on a steep slope.

• For Nissan Murano vehicles with the 2-batteries, be sure to connect the main battery and the sub battery before turning ON the ignition switch.

  NOTE:

  If the ignition switch is turned ON with any one of the terminals of main battery and sub battery disconnected, then DTC may be detected.

• After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC.

  NOTE:

  The removal of 12V battery may cause a DTC detection error.

AV COMMUNICATION SYSTEM

• Do not apply voltage of 7.0 V or higher to the measurement terminals.

• Use the tester with its open terminal voltage being 7.0 V or less.

• Be sure to turn ignition switch OFF and disconnect the battery cable from the negative terminal before checking the circuit.

AV COMMUNICATION SYSTEM

• Solder the repaired parts, and wrap with tape. [Frays of twisted line must be within 110 mm (4.33 in).]

  

• Do not perform bypass wire connections for the repair parts. (The spliced wire will become separated and the characteristics of twisted line will be lost.)
