SRS lamp
The supplementary restraint system (SRS) (4/9) contacts the driver information module (5/1) if there is a problem in the system. A signal is transmitted via the Control area network (CAN) and the driver information module lights a lamp and displays a text message. The combined instrument panel also informs the supplementary restraint system (SRS) whether the lamp is working or not.
