Operation

Operation due to brake pedal operation

1.  When the brake pedal is depressed, the brake switch (No.1 signal) turns on (1).

2.  When the brake switch (No.1 signal) turns on, a brake switch (No.1 signal) on signal is input (2) to the brake light unit.

3.  When the brake light unit receives a brake switch (No.1 signal) on signal, it supplies (3) current to the brake lights and high-mount brake light.

4.  The brake lights and high-mount brake light turn on (4).

Operation due to operation request signal from rear body control module (RBCM)

Note

•  For the operation conditions, refer to the [SMART CITY BRAKE SUPPORT [FORWARD] (SCBS F)], [SMART CITY BRAKE SUPPORT [REVERSE] (SCBS R)], and [SMART BRAKE SUPPORT (SBS)]. (See SMART CITY BRAKE SUPPORT [FORWARD] (SCBS F).) (See SMART CITY BRAKE SUPPORT [REVERSE] (SCBS R).) (See SMART BRAKE SUPPORT (SBS).)

1.  When the operation conditions are met, the rear body control module (RBCM) turns on (1) the transistor in the rear body control module (RBCM).

2.  When the transistor in the rear body control module (RBCM) turns on, the transistor A in the brake light unit turns on (2).

3.  When the transistor A in the brake light unit turns on, the transistor B in the brake light unit turns on (3).

4.  When the transistor B in the brake light unit turns on, current flows (4) to the brake lights and high-mount brake light.

5.  The brake lights and high-mount brake light turn on (5).
