Hyundai Santa Fe (TM): 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 LED lamp check.
The lamp shall turn on for 6 seconds during the initialization phase and turn
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 is turned on and blinks at intervals of 1 second
till the coding is completed.
In case the variant coding is normally completed, the airbag warning
lamp is turned on for 6 seconds, and then turned off. Otherwise the
airbag warning lamp continuously blinks at intervals of 1 second.
When there is active fault in the airbag system or SRSCM internal fault,
the variant coding (EOL) cannot be completed. In this case, do 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 is turned on continuously.
|
2. |
Loss of internal operating voltage : warning lamp is turned on continuously.
|
3. |
Loss of microprocessor operation : warning lamp is turned on continuously.
|
4. |
SRSCM not connected : warning lamp is turned on continuously.

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 below table.
Occupant Status |
Telltale Lamp |
PAB |
Empty |
ON |
Disabled |
Child (Small Occupant) |
ON |
Disabled |
Adult (Large Occupant) |
OFF |
Enabled |

OFF |
Enabled |
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.
