RS–82SUPPLEMENTAL RESTRAINT SYSTEM – AIRBAG SYSTEM
RS
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
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
