DESCRIPTION
The front airbag sensor RH consists of the diagnostic circuit, the frontal deceleration sensor, etc.
If the center airbag sensor assembly receives signals from the frontal deceleration sensor, it determines
whether or not the SRS should be activated.
DTC B1610/13 is recorded when a malfunction is detected in the front airbag sensor RH circuit.

INSTALLATION
HINT:
• Use the same procedures for the RH side and LH side.
• The procedures listed below are for the LH side.
CAUTION:
Be sure to read the precautionary notices concerning the
SRS airbag system before servicing it (see page RS-1).
1. INSTALL AIRBAG SENSOR REAR LH
(a) Install the airbag sensor with the bolt.
Torque: 9.0 N*m (92 kgf*cm, 80 in.*lbf)
NOTICE:
• If the airbag sensor has been dropped, or
there are any cracks, dents or other defects in
the case, bracket or connector, replace it with
a new one.
• When installing the airbag sensor, be careful
that the SRS wiring does not interfere with
other parts and that it is not pinched between
other parts.

RS–392SUPPLEMENTAL RESTRAINT SYSTEM – SEAT POSITION SENSOR
RS
INSTALLATION
CAUTION:
Be sure to read the precautionary notices concerning the
SRS airbag system before servicing it (see page RS-1).
1. INSTALL SEAT POSITION AIRBAG SENSOR
(a) Using a 1 mm (0.039 in.) feeler gauge, install the
seat position sensor.
NOTICE:
• If the seat position sensor has been dropped,
or there are any cracks, dents or other
defects in the case or connector, replace the
seat position sensor with a new one.
• When installing the seat position sensor, be
careful that the SRS wiring does not interfere
with other parts and that it is not pinched
between other parts.
HINT:
Be sure that the clearance between the seat
position sensor and the seat rail is within 0.6 mm to
1.4 mm (0.023 to 0.055 in.).
(b) Using a T30 "torx" socket, tighten the "torx" screw to
install the seat position sensor.
Torque: 8.0 N*m (82 kgf*cm, 71 in.*lbf)
(c) Make sure that the clearance between the seat
position sensor and the seat rail is within 0.6 mm to
1.4 mm (0.023 to 0.055 in.).
(d) Connect the connector.

RS
INSTALLATION
1. INSTALL OCCUPANT CLASSIFICATION ECU
(a) Check that the ignition switch is off.
(b) Check that the negative battery (-) terminal is
disconnected.
CAUTION:
After disconnecting the negative battery
terminal, wait for at least 90 seconds before
starting the operation.
(c) Install the occupant classification ECU.
(d) Connect the 2 connectors to the occupant
classification ECU.
NOTICE:
• If the occupant classification ECU has been
