SRS Control Module Kia Rio II

Airbag 4 illustrations ~379 words

DESCRIPTION

The primary purpose of the SRSCM (Supplemental Restraints System Control Module) is to discriminate between an event that warrants restraint system deployment and an event that does not. The SRSCM must decide whether to deploy the restrain system or not. After determining that pretensioners and/or airbag deployment is required, the SRSCM must supply sufficient power to the pretensioners and airbag igniters to initiate deployment.

The SRSCM determines that an impact may require deployment of the pretensioners and airbags from data obtained from impact sensors and other components in conjunction with a safing function. The SRSCM will not be ready to detect a crash or to activate the restraint system devices until the signals in the SRSCM circuitry stabilize. It is possible that the SRSCM could activate the safety restraint devices in approximately 2 seconds but is guaranteed to fully function after prove-out is completed. The SRSCM must perform a diagnostic routine and light a system readiness indicator at key-on. The system must perform a continuous diagnostic routine and provide fault annunciation through a warning lamp indicator in the event of fault detection. A serial diagnostic communication interface will be used to facilitate servicing of the restraint control system.

Scheme 32: INSTALLATION
  1. Disconnect the negative (-) cable from battery and wait for at least three minutes.
  2. Remove ignition key from the vehicle.
  3. Install the SRSCM with the SRSCM mounting bolts. Tightening Torque (SRSCM Mounting Bolt) : 1.0~1.4 kgf.m (9.5~13.5 Nm, 7.0~10.0 lb.ft)
  4. Connect the SRSCM harness connector.
  5. Install the floor console. (Refer to «INTERIOR»(ref-269624) )
  6. Connect the DAB, PAB, SAB, CAB and BPT connectors.
  7. Reconnect the battery negative cable.
  8. After installing the SRSCM, confirm proper system operation: Turn the ignition switch ON; the SRS indicator light should be turned on for about six seconds and then go off.
