Second Generation XM (2011-2019) / Kia Sorento XM 2011-2019 Service Manual / 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, side airbag and belt pretensioner in certain frontal or side collisions.
The SRS (Airbag) consists of ; a driver side airbag module located in the center of the steering wheel, which contains the folded cushion and an inflator unit ; a passenger side airbag module located in the passenger side crash pad contains the folded cushion assembled with inflator unit ; side airbag modules located in the front seat contain the folded cushion and an inflator unit ; curtain airbag modules located inside of the headliner which contains folded cushions and inflator units. The impact sensing function of the SRSCM is carried out by electronic accelerometer that continuously measure the vehicle’s acceleration and delivers a corresponding signal through amplifying and filtering circuitry to the microprocessor.
SRSCM (SRS Control Module)
SRSCM will detect front impact with front impact sensor, and side impact with side impact sensor, and determine airbag module deployment.
1.
Self diagnosis: SRSCM will constantly monitor current SRS operation status and detect system failure while vehicle power supply is on, system failure may be checked with trouble codes using GDS.
2.
Airbag warning lamp on: Upon detecting error, the module will transmit signal to airbag warning lamp located at cluster. Airbag warning lamp will indicate driver SRS error. Upon ignition key on, airbag warning lamp will turn on for about six seconds.
3.
Trouble code registration: Upon error occurrence in system, SRSCM will store DTC corresponding to the error. DTC can be cleared only by GDS. However, if an internal fault code is logged or if a crash is recorded the fault clearing should not happen.
4.
Self diagnostic connector: Data stored in SRSCM memory will be output to GDS or other external output devices through connector located below driver side crash pad.
5.
Once airbag is deployed, SRSCM should not be used again but replaced.
6.
SRSCM will detect whether passenger put on seat belt by the signal from built-in switch in seat belt buckle, and deploy front seat airbag at each set crash speed.
7.
Side airbag deployment will be determined by SRSCM that will detect satellite sensor impact signal upon side crash, irrespective to seat belt condition.
8.
SRSCM is sensing the vehicle rollover by using the rollover sensor. SAB, CAB, BPT will be able to expanse if mechanic moves the SRSCM during IGN ON state. For this reason, disconnect the battery negative cable during the SRSCM repair procedure.
9.
Check for the normal operation of SRSCM after repair procedure.
