CHASSIS ELECTRICAL 8-185
REAR WHEEL ANTI-LOCK BRAKE SYSTEM (RWAL)
GENERAL DESCRIPTION
The circuit consists of the starter switch, stoplight switch (vehicle w/o cruise control), brake switch (vehicle
w/cruise control). RWAL controller, RWAL speed sensor, RWAL valve, brake differential switch, 4WD switch,
parking brake
SW, indicator light (RWAL, 4WD, BRAKE), and test connector.
In this system, when the service brake is applied the RWAL controller judges the wheel rotation difference
signals which have been sent from the RWAL speed sensor at the rear axle differential. The anti-lock valves
control
the brake fluid pressure which is applied to the rear wheels to prevent the wheels from locking.
When starting the engine, the RWAL indicator in the instrument panel lights up at the same time as the brake
indicator
to inform the driver that the system is operating normally. (The light goes off after two seconds.)
Refer
to Section 5A3, "RWAL (REAR WHEEL ANTI-LOCK BRAKE SYSTEM)" for detail.
