Restraints (Except Troubleshooting): Other Kia Sorento I рестайлинг

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. DC/DC converter: DC/DC converter in power supply unit includes up/down transformer converter, and provide ignition voltage for 2 front airbag ignition circuits and the internal operation voltage of the SRSCM. If the internal operation voltage is below critical value setting, it will perform resetting.
2. Safety sensor: Safety sensor is located in airbag ignition circuit. Safety sensor will operate airbag circuit at any deployment condition and release airbag circuit safely at normal driving condition. Safety sensor is a double contact electro-mechanical switch that will close detecting deceleration above certain criteria.
3. Back up power supply: SRSCM has separate back up power supply, that will supply deployment energy instantly in low voltage condition or upon power failure by front crash.
4. 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 scan tool. (Hi-Scan).
5. Airbag 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.
6. Trouble code registration: Upon error occurrence in system, SRSCM will store 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 should not happen.
7. Self diagnostic connector: Data stored in SRSCM memory will be output to Hi-Scan or other external output devices through connector located below driver side crash pad.
8. Once airbag is deployed, SRSCM should not be used again but replaced.
9. SRSCM will determine 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.
10. Side airbag deployment will be determined by SRSCM that will detect satellite sensor impact signal upon side crash, irrespective to seat belt condition.

Scheme 43

1. Store the removed airbag with the pad surface up.
2. Keep free from any oil, grease, detergent, or water to prevent damage to the airbag assembly.
3. Store the removed airbag on secure, flat surface away from any high heat source (exceeding 85°C/185°F).
4. Never perform electrical inspections to the airbags, such as measuring resistance.
5. Do not position yourself in front of the airbag assembly during removal, inspection, or replacement.
6. Refer to the scrapping procedures for disposal of the damaged airbag.
7. Be careful not to bump or impact the SRS unit or the side impact sensors or front impact sensor whenever the ignition switch is ON, wait at least three minutes after the ignition switch is turned OFF before begin work.
8. During installation or replacement, be careful not to bump (by impact wrench, hammer, etc.) the area around the SRS unit and the side impact sensors and the front impact sensor. The airbags could accidentally deploy and cause damage or injury.
9. Replace the front airbag module, SRSCM, front impact sensor when deploying the front airbag. Replace the airbag wiring when the airbag wiring gets damaged. Replace the curtain airbag module, SRSCM, side impact sensors when deploying the curtain airbag. Replace the airbag when the airbag wiring gets damaged. After a collision in which the airbags or the side air bags did not deploy, inspect for any damage or any deformation on the SRS unit and the side impact sensors. If there is any damage, replace the SRS unit, the front impact sensor and/or the side impact sensors.
10. Do not disassemble the SRS unit, the front impact sensor or the side impact sensors.
11. Turn the ignition switch OFF, disconnect the battery negative cable and wait at least three minutes before beginning installation or replacement of the SRS unit.
12. Be sure the SRS unit, the front impact sensor and side impact sensors are installed securely with the mounting bolts.

WARNING LAMP BEHAVIOR AFTER IGNITION ON

As soon as the operating voltage is applied to the SRSCM ignition input, the SRSCM activates the warning lamp for a bulb check.

The lamp shall turn on for 6 seconds during the initialization phase and be turned off afterward. However, in order to indicate the driver, the warning lamp shall turn on for 6 seconds and off for one second then on continuously after the operating voltage is applied if any active fault exists.

Scheme 53

Scheme 54

1. Active fault or historical fault counter is greater or equal to 10
2. Normal or historical fault counter is less than 10

SRSCM INDEPENDENT WARNING LAMP ACTIVATION

There are certain fault conditions in which the SRSCM cannot function and thus cannot control the operation of the standard warning lamp. In these cases, the standard warning lamp is directly activated by appropriate circuitry that operates independently of the SRSCM. These cases are

1. Loss of battery supply to the SRSCM: warning lamp turned on continuously.
2. Loss of internal operating voltage: warning lamp turned on continuously.
3. Loss of Microprocessor operation: warning lamp turned on continuously.
4. SRSCM not connected: warning lamp turned on continuously through the shorting bar.

TELLTALE LAMP ACTIVATION

The Telltale Lamp indicates the Passenger Airbag (PAB) enabled and disabled status based on occupant status of passenger seat. If the passenger seat is empty or occupied with child (or child seat), the Passenger Airbag is disabled and the Telltale Lamp is turned ON to inform the driver that the PAB is disabled. As soon as operating voltage is applied to the SRSCM ignition input, the SRSCM activates telltale lamp prove out. OCS will send an defect status to the SRSCM as a default setting for passenger airbag deployment during the prove out period. Occupant status information and telltale status are as indicated on table. See TELLTALE LAMP ACTIVATION CHART .

TELLTALE LAMP ACTIVATION CHART

After ignition on, telltale lamp will turn on for 4 seconds and turn off for 4 seconds during the initialization phase and be turned off afterward until receipt of first valid suppression message from OCS system.
