The SRSCM shall perform a warning lamp bulb check. The lamp shall blink for 6 seconds (±10%), at 1Hz (± 10%), 50% duty cycle (± 10%), during the module power-on prove-out phase and be turned off afterwards.
The SRSCM shall perform a warning lamp check for 1 second after the initial 6 second prove-out period. If a recorded crash or an active fault is present at power-up or at least 10 different fault qualifications have been recorded, the airbag warning lamp output will be activated ON immediately after the 1 second lamp check.
When a current fault is detected at power-up, the lamp will not be affected until the end of prove-out. The lamp will blink normally at the rate defined in Case #1 above.
