ADDITIONAL SERVICE WHEN REPLACING CONTROL UNIT

ADDITIONAL SERVICE WHEN REPLACING CONTROL UNIT : Description

• When replacing the occupant classification system control unit, perform zero point reset procedure. Refer to SRC-42, "ZERO POINT RESET : Special Repair Requirement".
• When replacing the air bag diagnosis sensor unit configuration of the air bag diagnosis sensor unit is required. Refer to SRC-43, "CONFIGURATION : Work Procedure".

ZERO POINT RESET

ZERO POINT RESET : Description

Always perform zero point reset using CONSULT when removing and installing the passenger seat or servicing the occupant classification system. If zero point reset is not performed the OCS may not operate normally, which may increase the risk of serious injury in a collision. Zero point reset is an initializing procedure for occupant detection sensor that must be performed when replacing or removing and installing passenger seat.

If zero point reset is not performed, the initialization is incomplete and Occupant Detection System does not operate normally.

NOTE:

•  When zero point reset is performed once after removal and installation of passenger seat, CONSULT displays “complete”.
•  When reinstalling passenger seat after removal, the initial value for occupant detection sensor changes, and Occupant Detection System does not operate normally.
•  Always perform zero point reset after performing the work as per the following.

•  Reinstallation of passenger seat
•  Installation of passenger seat that is zero point reset complete
•  Installation of passenger seat that is zero point reset in complete

ZERO POINT RESET : Special Repair Requirement

1.PERFORM ZERO POINT RESET

1.  Perform zero point reset.

NOTE: When performing zero point reset, be careful of the items described as per the following:

•  Perform zero point reset after installing passenger seat to the vehicle
•  Do not put any objects on passenger seat
•  Do not apply excessive vibration to the vehicle
•  Do not touch the vehicle
•  Do not tilt the vehicle

2.  Select start on “Zero point reset function” screen from, WORK SUPPORT of CONSULT “OCCUPANT DETECTION”.
3.  “Zero point reset” starts.

>> GO TO 2.

2.CONFIRMATION OF SETTING

1.  Proceed to “Zero point reset function” screen from work support of CONSULT “OCCUPANT DETECTION”.
2.  Check that “Complete” or “Incomplete” is displayed on “Zero point reset status”.

CAUTION:

• “Complete” is displayed on “zero point reset current status” if the seat is reinstalled by seat removal and installation, or “zero point reset” is already performed.
• “Zero point reset current status” displays “Incomplete” if a new seat is installed. When turning key switch ON without performing zero point reset, front passenger air bag OFF indicator turns ON.

  When zero point reset is performed, front passenger air bag OFF indicator turns OFF.

•  Air bag warning lamp blinks in user mode only.
• Air bag sensor unit does not record whether or not zero point reset is performed.

Is condition “ALREADY PERFORMED”? YES >> Print out “ZERO POINT RESET CURRENT STATUS” screen, and inspection end.

NO >> Check condition as per the following, and perform zero point reset again.

•  Passenger seat is occupied by an object.
•  Excessive vibration is applied while performing zero point reset.
•  Occupant detection system is malfunctioning.

NOTE: If “Incomplete” is displayed on “zero point reset current status”, zero point reset is not completed normally. Check the condition as per the following and perform zero point reset again.

• Passenger seat is occupied by an object.

•  Excessive vibration is applied while performing zero point reset.
•  Occupant detection system is malfunctioning.

CONFIGURATION

CONFIGURATION : Description

When replacing air bag diagnosis sensor unit, save or print current vehicle specification with CONSULT configuration before replacement.

NOTE: If “Before Replace ECU” cannot be used, use the “After Replace ECU” or “Manual Configuration” after replacing air bag diagnosis sensor unit.

CONFIGURATION : Work Procedure

CAUTION:

•  When replacing ECU, you must perform “Write Configuration” with CONSULT.

•  Complete the procedure of “Write Configuration” in order.
•  If you set incorrect “Write Configuration”, incidents might occur.
•  Configuration is different for each vehicle model. Confirm configuration of each vehicle model.
•  Never perform “Write Configuration” except for new air bag diagnosis sensor unit.

•  When replacing BCM, perform the system initialization (NATS).

CONFIGURATION

Vehicle specification needs to be written with CONSULT because it is not written after replacing air bag diagnosis sensor unit.

Configuration has three functions as follows:

CAUTION:

•  When replacing air bag diagnosis sensor unit, you must perform “Select Saved Data List” or "After Replace ECU" with CONSULT.
•  Complete the procedure of “Select Saved Data List” or "After Replace ECU" in order.
•  If you set incorrect “Select Saved Data List” or "After Replace ECU", incidents might occur.
•  Configuration is different for each vehicle model. Confirm configuration of each vehicle model.
•  Never perform “Select Saved Data List” or "After Replace ECU" except for new air bag diagnosis sensor unit.

1.SAVING VEHICLE SPECIFICATION

CONSULT

Enter "Re/Programming, Configuration" and perform “Before Replace ECU” to save or print current vehicle specification.

NOTE: If “Before Replace ECU” cannot be used, use the "After Replace ECU" or "Manual Configuration" after replacing BCM.

>> GO TO 2.
