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.
Brake warning lamp
The brake control module (4/16) (called ABS module on model years up to and including 2001) informs the driver information module (5/1) via the
Control area network (CAN) if there is a fault in the brake system. The driver information module indicates this to the driver by lighting the red general
warning lamp and displaying a text message.
The brake fluid level sensor detects the level of the brake fluid in the reservoir. When the level is low, a switch in the sensor closes and the warning lamp
lights. This function is directly connected to the driver information module.
