CAUTION: Disconnect the negative battery cable before removing or installing any electrical unit or when a
tool or equipment could easily come in contact with exposed electrical terminals. Disconnecting this cable
will help prevent personal injury and damage to the vehicle. The ignition must also be in B unless otherwise
noted.
CAUTION: Don’t diagnosis the Antilock Brake System (ABS) under the vehicle moving status. Because the
ABS function will be stopped.

NORMAL BRAKE MODE
During non-antilock braking, pressure is applied through the brake pedal and fluid comes from the master cylinder into
the hydraulic unit. The normally open isolation cartridge and normally closed dump cartridge would remain in these
positions to allow fluid pressure to the calipers and the wheel cylinders. And each wheel begins locking.
