DTC B1013
DTC B1013 Seat weight sensor calibration error
Warning
• Detection conditions are for understanding the DTC outline before performing an inspection.
Performing an inspection according to only the detection conditions may cause injury due to
DETECTION
an operating error, or damage the system. When performing an inspection, always follow the
CONDITION
inspection procedure.
• Calibration set value not within valid range.
• Weight acting on passenger-side seat during calibration
• Improperly installed passenger-side seat part at time of calibration
• Deformed floor where attached to passenger-side seat
• Deformed passenger-side seat under-bracket or frame
POSSIBLE
• Seat weight sensor deformed or malfunction
CAUSE
• Seat weight sensor control module malfunction
• SAS control module malfunction
• Load to or deformation of the seat belt rail
Diagnostic procedure
STEP
1 INSPECT SEAT WEIGHT SENSOR
• Properly install the passenger-side front
seat.
• Inspect the seat weight sensor. (See 08-10-
12 SEAT WEIGHT SENSOR
CALIBRATION.)
• Is the seat weight sensor normal?
2 INSPECT PASSENGER-SIDE FRONT SEAT
• Turn the ignition switch to the LOCK position.
• Disconnect the negative battery cable and
wait for 1 min or more.
• Remove the passenger-side seat and
visually inspect for the following:
— Seat under-bracket deformation
— Seat frame deformation
— Seat weight sensor deformation
— Foreign objects stuck in seat
• Are any of the parts deformed or are any
foreign objects stuck in the seat?
