SRSCM (Supplemental Restraints System Control Module) checks input voltage when "IG ON" to make air bag system work properly.
If input voltage is out of normal range, there can be malfunction in system operation. In this case, Check battery and charging system.
The SRSCM sets DTC B1101 and turns warning light on if voltage above threshold value is detected for more than 4 sec.
(If voltage within threshold value is detected for 4 sec. SRSCM regards DTC as being cleared and turns warning light off)
