Kia Sedona: Description and Operation
Third generation YP (2014-2025) / Kia Sedona YP Service Manual / Restraint / Description and Operation
| Warning Lamp Activation |
| 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 lamp check.
The lamp shall turn on for 6 seconds during the initialization phase and be turned off afterward.
To alert 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.
| 1. |
Active fault or historical fault counter is greater or equal to 10.
|
| 2. |
Normal or historical fault counter is less than 10.
|
| 3. |
When turning the ignition switch ON during variant coding
(EOL) mode, the airbag warning lamp illuminates and blinks at intervals
of 1 second till the coding is completed.
In case the variant coding has successfully completed, the
airbag warning lamp will turn on for 6 seconds and then off. Otherwise,
the airbag warning lamp will continuously blink at intervals of 1
second.
When there is active fault in airbag system or SRSCM internal
fault, the variant coding (EOL) can’t be completed. In this case,
perform the variant coding (EOL) procedure again after troubleshooting
with the GDS.

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. |
Telltale Lamp Activation
The Telltale Lamp indicates the Passenger Airbag (PAB)
enabled and disabled status based on occupant status on passenger seat.
If the passenger seat is empty or occupied with a 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.
ODS (Occupant Detection System) will send an unknown status
to the SRSCM as a default setting for passenger airbag deployment during
the validation period.
After ignition on, telltale lamp will turn on for 4 seconds
and turn off for 3 seconds during the initialization phase and be turned
ON afterward until receipt of valid enabled message from ODS system.
