Components and Connectors

Three warning lamps alert the driver in case of problems in the braking system. The brake pad switch H10, which is formed by a microswitch located on the pads, is grounded when the pad becomes too thin and as a result sends a signal to the instrument panel C10 at pin 1 of connector D (pin 5 of connector B for the sports-type instrument panel B) and lights the relative "brake pad wear" warning lamp.

The handbrake switch H1 and the brake fluid minimum level check switch H17 (these also are two microswitches which send a ground signal) supply the signal to the instrument panel C10 at pin 7 of connector C; both react by lighting the "handbrake on or low brake fluid level" warning lamp.

The first closes when when the handbrake lever is raised and the second when the level of fluid in the braking system falls below a certain level in the reservoir.

The third warning lamp relative to the braking system is that of the "ABS system malfunction" which is described in that section (see "ABS system").
