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 will turn on for 6 seconds during the initialization phase and will then turn off afterward.
If there are any active faults after the operating voltage is
applied, the warning lamp will flicker on for 6 seconds and off for 1
second to alert the driver.
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.
When the variant coding is successfully completed, the airbag
warning lamp will turn on for 6 seconds and then turn off. Otherwise,
the airbag warning lamp will continuously flicker at intervals of 1
second.
(1)
In case the variant coding is successfully completed
(2)
In case the variant coding is not completed
When there is active fault in airbag system or SRSCM internal
fault, the variant coding (EOL) cannot 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 include:
1.
Loss of battery sypply to the SRSCM : warning lamp stays on
2.
Loss of internal operating voltage : warning lamp stays on
3.
Loss of Microprocessor operation : warning lamp stays on
4.
SRSCM not connected : warning lamp stays on through the shorting bar
Telltale Lamp Activation
The Telltale Lamp indicates whether the Passenger Airbag
(PAB) is enabled or disabled according to the occupant status on
passenger seat. If the passenger seat is empty or occupied with a child
(or a 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 to prove out. 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 turning the ignition on, talltale lamp will turn on for
4 seconds and turn off for 3 seconds during the initialization phase
and will keep ON afterward until receiving a valid enabling message from
ODS system.
