| 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 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 faults exist.
|
| 2. |
No active faults or crash records
exists.
|
| 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.
| (1) |
In case the variant coding is normally
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) can’t 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 airbag warning lamp. In these cases, the airbag 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. |
