| 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 |
| Defect | 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.
