Toyota RAV4 (XA40) 2013-2018 Service Manual: Initialization
- Zero point calibration
Notice:
Make sure that the front passenger seat is not
occupied before performing the operation.
Hint:
Perform the zero point calibration and sensitivity check if
any of the following conditions apply.
- The occupant classification ecu is replaced.
- Accessories (seat cover etc.) Are installed.
- The front passenger seat is removed from the vehicle.
- The passenger airbag on/off indicator (off)
comes on when the front passenger seat is not
occupied.
- The vehicle is brought to the workshop for repair due
to an accident or a collision.
- Zero point calibration and sensitivity check
procedures:
Hint:
Make sure that the zero point calibration has
finished normally, and then perform the sensitivity
check.
- Adjust the seat position in accordance with the
table below.


- Connect the intelligent tester (with can vim) to
the dlc3.
- Turn the ignition switch on.
- Perform the zero point calibration by following
the prompts on the tester screen.

Hint:
Refer to the intelligent tester operator's manual
for further details.
Ok:
completed is displayed.
- Perform the sensitivity check by following the
prompts on the tester screen.
- Confirm that the beginning sensor reading is
within the standard range.
Standard range:
-3.2 To 3.2 Kg (-7 to 7 lb)
- Place a 30 kg (66.14 Lb) weight (e.G. A lead
mass) onto the front passenger seat.
- Confirm that the sensitivity is within the standard
range.

Standard range:
27 to 33 kg (59.52 To 72.75 Lb)
Hint:
- When performing the sensitivity check, use a
solid metal weight (the check result may not
be accurate if a liquid weight is used).
- If the sensitivity deviates from the standard
range, retighten the bolts of the front
passenger seat taking care not to deform the
seat rail. After performing this procedure, if
the sensitivity is not within the standard
range, replace the front seat assembly rh.
- If the zero point calibration has not finished
normally, replace the front seat assembly rh.

Hint:
The skid control ecu forms a single unit with the abs
and traction actuator.
Abs (anti-lock brake system):
the abs helps prevent the wheels from locking
when the brakes are applied firmly or on a slippery
surface.

Test mode procedure
Hint:
By switching the skid control ecu from normal mode to
test mode, abnormality detection sensitivity is enhanced
and troubleshooting can be conducted efficiently.
Perform a sensor check in test mode after the speed
sensor or sensor rotor has been repaired or replaced.
