INFOID:0000000009460735
WARNING:
Always perform zero point reset using CONSULT when removing an d installing the front 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.
ADDITIONAL SERVICE WHEN REPLACING CONTROL UNIT : Special Repair Re-
quirement

WORK PROCEDURE WHEN REPLACING OCS CONTROL UNIT
1.PERFORM ZERO POINT RESET
Perform zero point reset. Refer to SRC-42, "ZERO POINT RESET : Special Repair Requirement"
.
>> Inspection End.
ZERO POINT RESET
ZERO POINT RESET : DescriptionINFOID:0000000009460737
Zero point reset is an initializing procedure for the OCS (weight) sensors that must be performed using CON-
SULT when removing and installing passenger seat or servic ing the OCS system. If zero point reset is not per-
formed, the initialization is incomplete and OCS may not operate normally.
NOTE:
• When reinstalling the passenger seat, the initial value for the OCS sensors may change, and the OCS may
not operate normally.
• When zero point reset is performed after removal and installation of passenger seat, CONSULT displays "complete".
ZERO POINT RESET : Spec ial Repair RequirementINFOID:0000000009460738
1.PERFORM ZERO POINT RESET
1. Perform preliminary checks: NOTE:
• Level the vehicle
• Minimize vibrations near the vehicle
• Remove any objects on passenger seat
• Do not touch the vehicle during zero point reset
2. Select START on ZERO POINT RESET from , WORK SUPPORT of “OCCUPANT DETECTION”.
3. “Zero point reset” starts.
>> GO TO 2.
2.CONFIRM RESET
1. Check that "Complete" is displayed on “Zero point reset status”.
CAUTION:
• “Complete” may be displayed if the seat has been reinstalled, or “zero point reset” has already been
performed.
• "Incomplete” may be displayed if a new seat is installed.
• Air bag warning lamp flashes in user mode if zero point reset is "incomplete".
Is zero point reset status "complete"?
YES >> Print out “ZERO POINT RESET CURRENT STATUS” screen. Inspection end.
NO >> Recheck the preliminary check items and perform zero point reset again.
