Active fault or historical fault counter is greater or equal to 10.
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.
Active fault or historical fault counter is greater or equal to 10.
Normal or historical fault counter is less than 10.
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.
In case the variant coding is normally completed
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.
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:
Loss of battery supply to the SRSCM : warning lamp turned on continuously.
Loss of internal operating voltage : warning lamp turned on continuously.
Loss of Microprocessor operation : warning lamp turned on continuously.
SRSCM not connected : warning lamp turned on continuously.
