DRIVE-CONTROL COMPONENTS -

STOP LAMP SWITCH
This switch turns on when the brake pedal is
depressed, and turns off when the brake pedal
is released. The ABS-ECU detects whether the
stop lamp switch is on or off by means of fluctuations
in voltage (ON: system voltage; OFF: Approximately
0 V). This data is used for ABS control.
PARKING BRAKE SWITCH
This switch turns on when the parking brake lever
is pulled, and turns off when the parking brake
lever is released. The ABS-ECU detects whether
the parking brake switch is on or off by means
of fluctuations in voltage (ON: less than 1V; OFF:
system voltage). This data is used for ABS control.
ACTUATORS
ABS WARNING LAMP
The ABS-ECU controls the power transistor in ABS-ECU to
turn on and causes the ABS warning lamp to illuminate in
the following cases:
D
During initial check when the ignition switch is at the
“ON” position (for approximately 3 seconds)
D
When a problem happens in the ABS/EBD system
D
Poor ABS-ECU connector connection
HYDRAULIC UNIT
The hydraulic unit is basically the same as that of the 1999
