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
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.
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.
