Warning Lamp Activation: Notes

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 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 illuminates and blinks at intervals of 1 second till the coding is completed.

   In case the variant coding is completed normally, 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.
