SYSTEM DESCRIPTION
1. DESCRIPTION OF SUPPLEMENTAL RESTRAINT SYSTEM
(a) General description.
In this system, the airbag sensor assembly installed on the floor under the A/C unit determines whether
or not to activate the SRS airbags (driver airbag, passenger airbag, front seat airbags and curtain
shield airbags) and seat belt pretensioners by receiving the collision signal from each sensor (exclud-
ing the airbag sensor assembly). When there is trouble in the system, the airbag sensor assembly turns
on the SRS warning light on the combination meter to inform the driver.
(b) Description of the dual stage control.
The airbag sensor assembly controls the dual stage deployment of the driver airbag in the steering
wheel pad and the passenger airbag on the instrument panel. The airbag sensor assembly controls
the dual stage deployment of the driver airbag according to the collision impact, seat position and seat
belt ON/OFF state. It also controls the dual stage deployment of the passenger airbag according to
the collision impact and seat belt ON/OFF state.
(c) Description of the roll±over function.
(1) The airbag sensor assembly detects inclination signals from the inclination sensor installed on
the vehicle. The roll±over function ensures passenger safety by using these signals to activate
the RH and LH curtain shield airbag assembly and seat belt pretensioner when vehicle inclination
exceeds the specified value.
(2) An RSCA OFF switch (roll±over sensing curtain shield airbag OFF switch), which allows optional
deactivation of the roll±over function, is installed on the vehicle.
(d) Description of check mode (signal check).
This airbag sensor assembly is operable using the check mode of the hand±held tester function. Check
mode can detect and output DTC by using a hand±held tester to switch the airbag sensor assembly
to the check mode.
A simulation method is used, if the malfunction cannot be reproduced during troubleshooting (the mal-
function is temporarily solved, etc.). In this case, joggling each connector, or driving on a city or rough
road with the airbag sensor assembly in check mode makes it possible to obtain a more accurate mal-
function condition.
