The supplementary restraint system (SRS) (4/9) contacts the driver information module (DIM) (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 (DIM) lights the SRS lamp and displays a text message. The driver information module (DIM) also informs the supplemental restraint system module (SRS) whether the indicator lamp is working or not. A text message is displayed and the red warning lamp lights if the SRS warning lamp is not working.
