(5)

Perform the sensitivity check by following the
prompts on the tester screen shown in 2 pages lat-
er.

(6)

Confirm that the beginning sensor reading is within
the standard value.

OK:

Standard value: –3.2 to 3.2 kg (–7 to 7 lb)
(7)

Place a 30 kg (66.14 lb) weight (eg. a 30 kg (66.14
lb) of lead mass) onto the passenger seat.

(8)

Confirm that the sensitivity is within the standard
value.

OK:

Standard value: 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 appear properly if the
weight made from liquid is used).

When the sensitivity deviates from the standard value, re-
tighten the bolts of the passenger seat taking care not to
deform the seat rail. After performing this procedure, if the
sensitivity is not within the standard value, replace the
front seat assembly RH.

When zero point calibration has not finished normally, re-
place the front seat assembly RH.
