WORK PROCEDURE WHEN REPLACING CONTROL UNIT
1.PERFORM ZERO POINT RESET
Perform zero point reset. Refer to SRC-39, "
ZERO POINT RESET : Special Repair Requirement".
Is zero point reset performed normally?
YES >> 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 cu rrent 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.

ZERO POINT RESET : DescriptionINFOID:0000000012430614
Zero point reset is an initializing procedure for occupant detection sensor that must be performed when replac-
ing or removing and installing passenger seat.
If zero point reset is not performed, the initializati on 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 dis- plays “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 RequirementINFOID:0000000012430615
