2008 RESTRAINTS

On-Board Diagnostic (Restraints) - Mazda CX-9

FOREWORD

OUTLINE

 The OBD (on-board diagnostic) system has the following functions:

 Malfunction detection function: Detects malfunctions in the air bag system and outputs DTCs.  Data monitor function: Reads out specific input/output signals and the system status.

 Diagnostic DTCs can be read/cleared using the M-MDS.

FLOWCHART

 Use the following flowchart to verify the cause of the trouble.

NOTE:

 While performing the inspection of the past malfunction code, the

applicable DTCs may be added to memory by removing or disconnecting the related parts. Inspect only the DTCs that were indicated before inspecting.

 When DTCs of the present malfunction are no longer output after present

or past malfunctions or both have been repaired, be sure to perform past malfunction display cancellation to prevent repair of malfunctions that have already been repaired.

AIR BAG SYSTEM SERVICE WARNINGS

AIR BAG MODULE INSPECTION

 Inspecting an air bag module using a tester can operate (deploy) the air bag module, which may

cause serious injury. Do not use a tester to inspect an air bag module. Always use the on-board diagnostic function to diagnose the air bag module for malfunctions.

Fig. 2: Precaution For Air Bag Module Inspection Courtesy of MAZDA MOTORS CORP.

AIR BAG MODULE HANDLING

 Before removing the air bag module or disconnecting the air bag module connector, always turn

the ignition switch to the LOCK position, disconnect the negative battery cable, and then wait for 1 min or more to allow the backup power supply of the SAS control module to deplete its stored power.

 Handling a live (undeployed) air bag module that is pointed toward your body could result in

serious injury if the air bag module were to accidentally operate (deploy). When carrying a live (undeployed) air bag module, point the deployment surface away from your body to lessen the chance of injury in case it operates (deploys).

Fig. 3: Precaution For Air Bag Module Handling

g

2008 Mazda CX-9 Grand Touring

2008 RESTRAINTS Air Bag System - Mazda CX-9

 A live (undeployed) air bag module placed with its deployment surface to ground is dangerous. If

the air bag module were to accidentally operate (deploy), it could cause serious injury. Always place a live (undeployed) air bag module with its deployment surface up.

Fig. 4: Precaution For Air Bag Module Handling Courtesy of MAZDA MOTORS CORP.

SIDE AIR BAG MODULE HANDLING

 Before removing the side air bag module or disconnecting the side air bag module connector,

always turn the ignition switch to the LOCK position, disconnect the negative battery cable, and then wait for 1 min or more to allow the backup power supply of the SAS control module to deplete its stored power.

 When a side air bag module operates (deploys) due to a collision, the interior of the seat back (pad,

frame, trim) may become damaged. If a side air bag does not operate (deploy) normally from a seat back that has been reused, a serious accident may result. After a side air bag has operated (deployed), always replace both the side air bag module and the seat back (pad, frame, trim) with new parts. After servicing, verify that the seat operates normally and that the wiring harness is not caught.

SEAT WEIGHT SENSOR HANDLING

 The front passenger-side seat and the seat weight sensor may become deformed or otherwise

damaged due to operation (deployment) of the front or side air bag in an accident. This may cause the passenger sensing function to operate improperly and result in a serious accident. Always replace the ' front passenger seat and seat weight sensor with new ones after the front or side air bags have operated (deployed). After servicing, verify that the seat operates normally and that the wirin

harness is not caught. If the collision is not hard enough to cause the front or side air bags to

operate (deploy), inspect the seat weight sensor and replace it if there is any malfunction.

SAS CONTROL MODULE HANDLING

 Removing the SAS control module or disconnecting the SAS control module connector with the

ignition switch at the ON position can activate the sensor in the SAS control module and operate

g

2008 Mazda CX-9 Grand Touring

2008 RESTRAINTS Air Bag System - Mazda CX-9

the SAS control module or disconnecting the SAS control module connector, always turn the ignition switch to the LOCK position, disconnect the negative battery cable, and then wait for 1 min or more to allow the backup power supply of the SAS control module to deplete its stored power.

 Connecting the SAS control module connector with the SAS control module not securely fixed to

the vehicle is dangerous. The sensor in the SAS control module could send an electrical signal to the air bag modules and pre-tensioner seat belts. This will operate (deploy) the air bags and pretensioner seat belts, which may result in serious injury. Therefore, before connecting the connector, securely fix the SAS control module to the vehicle.

 Because a sensor is built into the SAS control module, once the air bags and pre-tensioner seat belts

have operated (deployed) due to a collision or other causes, the SAS control module must be replaced with a new one even if the used one does not have any visible external damage or deformation. The used SAS control module may have been damaged internally, which may cause improper operation. If the SAS control module is reused, the air bags and pre-tensioner seat belts may not operate (deploy) normally, which could result in a serious accident. Always replace the SAS control module with a new one. The SAS control module cannot be bench-checked or selfchecked.

CRASH ZONE SENSOR HANDLING

 Removing the crash zone sensor or disconnecting the crash zone sensor connector with the ignition

switch at the ON position can activate the crash zone sensor and operate (deploy) the air bags and pre-tensioner seat belts, which may cause serious injury. Before removing the crash zone sensor or disconnecting the crash zone sensor connector, always turn the ignition switch to the LOCK position, disconnect the negative battery cable, and then wait for 1 min or more to allow the backup power supply of the SAS control module to deplete its stored power.

 If the crash zone sensor is subjected to shock or the sensor is disassembled, the air bags and pre-

tensioner seat belts may accidentally operate (deploy) and cause injury, or the system may fail to operate normally and cause a serious accident. Do not subject the crash zone sensor to shock or disassemble the sensor.

 Because a sensor is built into the crash zone sensor, once the air bags and pre-tensioner seat belts

have operated (deployed) due to a collision or other causes, the crash zone sensor must be replaced with a new one even if the used one does not have any visible external damage or deformation. If the crash zone sensor is reused, the air bags and pre-tensioner seat belts may not operate (deploy) normally, which could result in a serious accident. Always replace the crash zone sensor with a new one. The crash zone sensor cannot be bench-checked or self-checked.

SIDE AIR BAG SENSOR HANDLING

 Removing the side air bag sensor or disconnecting the side air bag sensor connector with the

ignition switch at the ON position can activate the side air bag sensor and operate (deploy) the side air bag, which may cause serious injury. Before removing the side air bag sensor or disconnecting the side air bag sensor connector, always turn the ignition switch to the LOCK position, disconnect the ne

ative battery cable, and then wait for 1 min or more to allow the backup power supply of the

SAS control module to deplete its stored power.

 If the side air bag sensor is subjected to shock or the sensor is disassembled, the side air bag may

accidentally operate (deploy) and cause injury, or the system may fail to operate normally and

PRE-TENSIONER SEAT BELT INSPECTION

 Inspecting a pre-tensioner seat belt using a tester can operate (deploy) the pre-tensioner seat belt,

which may cause serious injury. Do not use a tester to inspect a pre-tensioner seat belt. Always use the on-board diagnostic function to diagnose the pre-tensioner seat belt for malfunctions.

SEAT WEIGHT SENSOR HANDLING

 The seat weight sensor has a built-in strain gauge which may operate improperly if the sensor is

dropped by itself or when installed to the seat. If it is dropped, replace the seat weight sensor with a new one.

 Oil, grease, or water on the seat weight sensor may cause the system to operate (deploy)

improperly. Never allow oil, grease, or water to get on the seat weight sensor.

 Foreign material in the seat weight sensor components may cause the system to operate (deploy)

improperly. Always make sure that no foreign material can get into the seat weight sensor.

 Disassembling the seat weight sensor, or tightening any of the nuts and bolts installed to the sensor

body may cause it to operate (deploy) improperly. Never disassemble the seat weight sensor or tighten any of the nuts or bolts installed to the body of the sensor.

AIR BAG MODULE, PRE-TENSIONER SEAT BELT REUSE

 Even if an air bag module or a pre-tensioner seat belt does not operate (deploy) in a collision and

does not have any external signs of damage, it may have been damaged internally, which may cause improper operation. Before reusing a live (undeployed) air bag module and the pre-tensioner seat belts, always use the on-board diagnostic to diagnose the air bag module and the pre-tensioner seat belts to verify that they have no malfunction.
