Kia Sorento: Description and Operation
|
•
|
The airbag system is a supplemental restraint system to protect the driver and passengers from injuries by
operating the airbags and seat belt pretensioner installed on the driver's and front passenger's
seats in the event of a vehicle collision.
|
|
•
|
The airbag system is configured as follows.
|
|
–
|
Airbag Control Unit (ACU)
|
|
–
|
Front Impact Sensor (FIS)
|
|
–
|
Side Impact Sensor (SIS)
|
|
–
|
Seat Belt Pretensioner (BPT)
|
|
–
|
Airbag and seat belt warning lamp
|
The airbag control unit turns on the airbag warning lamp by detecting whether there is an abnormality in the airbag
system when the power is applied.
| 1. |
When the airbag system is normal.
|
–
|
When the airbag system is normal, the airbag warning lamp turns on for 3 to 6 seconds and turns
off.
|
|
| 2. |
If there is any problem with the airbag system.
|
–
|
If there is a problem with the airbag system, the warning lamp will be on for 6 seconds, then go
off for 1 second, then come back on and stay on.
|
|
| 3. |
When in the variant coding (EOL) mode.
|
–
|
When the IG is ON, the airbag warning lamp turns on for 3 seconds.
|
|
–
|
The airbag warning lamp blinks at 1 second intervals until the variant coding (EOL) is normally
completed.
|
|
–
|
When variant coding (EOL) is normally completed, the airbag warning lamp turns on for 6 seconds and
then turns off.
|
|
–
|
When variant coding (EOL) is not normally completed, the airbag warning lamp continues to blink at
1 second intervals.
|
| (1)
|
When variant coding (EOL) is normally completed.
|
| (2)
|
When variant coding (EOL) is not normally completed.
|
|
|
•
|
If there is a failure of the airbag system or an internal failure of the airbag system control
module, variant coding (EOL) should be re-performed after confirming the cause of failure and
completing the action using the KDS.
|
|
•
|
In the following cases, the airbag warning light continues to illuminate.
|
|
–
|
If there is a failure of the airbag system or an internal failure of the airbag control unit.
|
|
–
|
If there is a Diagnostic Trouble Code (DTC).
|
|
–
|
While communicating with the airbag control unit by using the KDS.
|
|
•
|
If a failure occurs in which the airbag control module cannot operate, the operation of the airbag
warning lamp cannot be controlled normally.
|
|
•
|
In the following cases, the airbag warning lamp turns on by using a circuit that operates
independently of the airbag control unit.
|
|
–
|
Loss of battery power in the airbag system control unit : The airbag warning lamp stays on.
|
|
–
|
Loss of internal operating voltage: The airbag warning lamp stays on.
|
|
–
|
Loss of airbag control unit operation : The airbag warning lamp stays on.
|
|
–
|
Not connected airbag control unit.
