Kia Soul EV: Restraint / General Information

Kia Soul EV (PS EV) 2015-2020 Service Manual / Restraint / General Information

General

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.
