Kia Soul EV: Restraint / General Information
The supplemental restraint system (SRS) is designed to
supplement the seat belt to help reduce the risk or severity of injury
to the driver and passenger by activating and deploying the driver,
passenger and side airbags and belt pretensioners in certain frontal or
side collisions.
The SRS consists of ; a driver side airbag module located in
the center of the steering wheel which contains a folded cushion and an
inflator unit ; a passenger side airbag module located in the passenger
side crash pad which contains a folded cushion assembled with an
inflator unit ; a side airbag module located in the front seat which
contains folded cushions and inflator units ; and curtain airbag modules
located inside headliners which contain folded cushions and inflator
units. The impact sensing function of the SRSCM is carried out by
electronic accelerometer that continuously measures the vehicle’s
acceleration and delivers a corresponding signal through amplifying and
filtering circuitry to the microprocessor.
SRSCM (SRS Control Module)
SRSCM detects front impact from the front impact sensor and
side impact from the side impact sensor and determines the airbag module
deployment.
1. |
DC/DC Converter: DC/DC converter in power supply unit
includes up/down transformer converter, and provides ignition voltage to
2 front airbag ignition circuits and internal operation voltage to the
SRSCM. If the internal operation voltage is below critical value
setting, it will reset. |
2. |
Back up power supply: SRSCM has a separate back up power
supply which will instantly supply deployment energy in low voltage
condition or upon power failure due to front crash. |
3. |
Self diagnosis: SRSCM will constantly monitor current SRS
operation status and detect system failure when the vehicle power supply
is on. System failure may be checked by trouble codes using GDS. |
4. |
SRS warning lamp on: Upon detecting error, the module will
transmit signal to SRSCM indicator lamp located at cluster. MIL lamp
will indicate driver SRS error. Upon ignition key on, SRS lamp will turn
on for about six seconds. |
5. |
Trouble code registration: When an error occurs in the
system, SRSCM will save DTC corresponding to the error. DTC can be
cleared only by Hi-Scan. However, if an internal fault code is logged or
if a crash is recorded, the fault clearing will not happen. |
6. |
Self diagnostic connector: Data stored in SRSCM memory will be viewed using GDS. |
7. |
Once airbag is deployed, SRSCM should be replaced with new SRSCM. |

Description
The ventilated seat system generates cool wind by the Push
method in the blower mounted under the seat which then travels through
ducts to the seat back and cushion.
