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 " 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

WARNINGAlways observe the following items for preventing accidental activation. When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never 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.

For details, refer to " DOOR LOCK FUNCTION: SYSTEM DESCRIPTION ". To open back door by operating back door opener switch, Intelligent Key must be within the detection area of outside key antenna. For details, refer to " BACK DOOR OPEN FUNCTION: SYSTEM DESCRIPTION ".

DISARMED Phase

The vehicle security system is not set in the DISARMED phase. The vehicle security system stays in this phase while any door is open, because it is assumed that the owner is inside or nearby the vehicle. Security indicator lamp blinks every 2.4 seconds.

When the vehicle security system is reset, each phase switches to the DISARMED phase directly.

PRE-ARMED Phase

The PRE-ARMED phase is the transient state between the DISARMED phase and the ARMED phase. This phase is maintained for 30 seconds, so that the owner can reset the setting due to a mis-operation. This phase switches to the ARMED phase when vehicle conditions are not changed for 30 seconds. Security indicator lamp illuminates while being in this phase.

To reset the PRE-ARMED phase, refer to the switching condition of No. 10 in the table above.

ARMED Phase

The vehicle security system is set, and BCM monitors all necessary inputs. If any door is opened without using Intelligent Key function, vehicle security system switches to the ALARM phase. Security indicator lamp blinks every 2.4 seconds.

To reset the ARMED phase, refer to the switching condition of No. 11 in the table above.

ALARM Phase

BCM transmits "Theft Warning Horn Request" signal and "High Beam Request" signal intermittently to IPDM E/R via CAN communication. In this phase, horns and headlamps are activated intermittently for approximately 50 seconds to warn that the vehicle is accessed by unauthorized means. ON/OFF timing of horns and headlamps are synchronized.

To cancel the ALARM operation, refer to the switching condition of No. 12 in the table above.

Note. If a battery terminal is disconnected during the ALARM phase, theft warning alarm stops. But when the battery terminal is reconnected, theft warning alarm is activated again.

REALARM Phase

When ALARM phase is maintained for 50 seconds without any cancel operation, the system status returns to the ARMED phase. At this time, if BCM still detects unauthorized access to the vehicle, the system is switched to the ALARM phase again. This REALARM operation is carried out a maximum of 2 times.

PRE-RESET Phase

The PRE-RESET phase is the transient state between each phase and DISARMED phase.

The PRE-RESET phase is not available for this models.

PANIC ALARM

  1. The panic alarm function activates horns and headlamps intermittently when the owner presses the PANIC ALARM button of Intelligent Key outside the vehicle while the ignition switch is OFF.
  2. When BCM receives panic alarm signal from Intelligent Key, BCM transmits "Theft Warning Horn Request" signal and "High Beam Request" signal intermittently to IPDM E/R via CAN communication. To prevent the activation due to mis-operation of Intelligent Key by owner, the panic alarm function is activated when BCM receives the signal for 0.4 - 0.6 seconds.
  3. Panic alarm operation is maintained for 25 seconds.
  4. Panic alarm operation is cancelled when BCM receives one of the following signals. LOCK button of Intelligent Key: ON UNLOCK button of Intelligent Key: ON BACK DOOR OPEN button of Intelligent Key: ON PANIC ALARM button of Intelligent Key: Long pressed Any door request switch: ON

DETAILED FLOW

  1. GET INFORMATION FOR SYMPTOM Get detailed information from the customer about the symptom (the condition and the environment when the incident/malfunction occurs). Check operation condition of the function that is malfunctioning. : GO TO 2.
  2. CHECK DTC Check DTC. Perform the following procedure if DTC is detected. Record DTC and freeze frame data (Print them out using CONSULT.) Erase DTC. Study the relationship between the cause detected by DTC and the symptom described by the customer. Check related service bulletins for information. Are any symptoms described and any DTC detected? Symptom is described, DTC is detected: GO TO 3. Symptom is described, DTC is not detected: GO TO 4 . Symptom is not described, DTC is detected: GO TO 5 .
  3. CONFIRM THE SYMPTOM Try to confirm the symptom described by the customer. Also study the normal operation and fail-safe related to the symptom. Verify relation between the symptom and the condition when the symptom is detected. : GO TO 5 .
  4. CONFIRM THE SYMPTOM Try to confirm the symptom described by the customer. Verify relation between the symptom and the condition when the symptom is detected. : GO TO 6 .
  5. PERFORM DTC CONFIRMATION PROCEDURE Perform DTC CONFIRMATION PROCEDURE for the detected DTC, and then check that DTC is detected again. At this time, always connect CONSULT to the vehicle, and check self diagnostic results in real time. If two or more DTCs are detected, refer to " «DTC INSPECTION PRIORITY CHART»(ref-672646-S06454220412014112400000) " (BCM), and determine trouble diagnosis order. NOTE: Freeze frame data is useful if the DTC is not detected. Perform Component Function Check if DTC CONFIRMATION PROCEDURE is not included on Service Information. This simplified check procedure is an effective alternative though DTC cannot be detected during this check. If the result of Component Function Check is NG, it is the same as the detection of DTC by DTC CONFIRMATION PROCEDURE. Is DTC detected? YES: GO TO 7 . NO: Check according to " «INTERMITTENT INCIDENT»(ref-672611-S01525861502014112400000) ".
  6. DETECT MALFUNCTIONING SYSTEM BY SYMPTOM DIAGNOSIS Detect malfunctioning system according to SYMPTOM DIAGNOSIS based on the confirmed symptom in step 4 , and determine the trouble diagnosis order based on possible causes and symptom. Is the symptom described? YES: GO TO 7. NO: Monitor input data from related sensors or check voltage of related module terminals using CONSULT.
  7. DETECT MALFUNCTIONING PART BY DIAGNOSIS PROCEDURE Inspect according to Diagnosis Procedure of the system. Is malfunctioning part detected? YES: GO TO 8. NO: Check according to " «INTERMITTENT INCIDENT»(ref-672611-S01525861502014112400000) ".
  8. REPAIR OR REPLACE THE MALFUNCTIONING PART Repair or replace the malfunctioning part. Reconnect parts or connectors disconnected during Diagnosis Procedure again after repair and replacement. Check DTC. If DTC is detected, erase it. : GO TO 9.
  9. FINAL CHECK When DTC is detected in step 2 , perform DTC CONFIRMATION PROCEDURE again, and then check that the malfunction is repaired securely. When symptom is described by the customer, refer to confirmed symptom in step 3 or 4 , and check that the symptom is not detected. Is DTC detected and does symptom remain? YES-1: DTC is detected: GO TO 7 . YES-2: Symptom remains: GO TO 4 . NO: Before returning the vehicle to the customer, always erase DTC.
