SYSTEM DESCRIPTION
1. GENERAL
(a) Deceleration sensors used for the airbag system are installed on various parts on the vehicle and calculate the deceleration rate of each part during a collision.
(b) Depending on the situation, the center airbag sensor assembly sends a deployment signal to airbag and pretensioner based on the information from each sensor.
2. DEPLOYMENT CONDITION
(a) FRONTAL COLLISION
(1) Frontal collision signals are produced based on the information from the center airbag sensor assembly and front airbag sensors.
HINT:
*: In case of a frontal collision, the SRS ignition signal could be output with the deceleration sensor ON signal even without a signal from the front airbag sensors.
(2) Frontal collision signals are used to deploy the airbags and pretensioners except the side airbags.
(b) SIDE COLLISION (1)
(1) The side airbags are deployed based on signals from the side airbag sensors and center airbag sensor assembly.
HINT:
The curtain shield airbags and front pretensioners are deployed at the same time.
(c) SIDE COLLISION (2)
(1) The curtain shield airbags are deployed when both of the following conditions are met:

MONITOR DESCRIPTION
The ECM continuously monitors its main and sub CPUs while cruise control is operating.
This self-check ensures that the ECM is functioning properly. If outputs from the
CPUs are different and deviate from the standard, the ECM illumina ...
