(b) Turn the selector switch of the Actuator checker to "FRONT LH" position.
(c) Push and hold in the MOTOR switch for a few seconds.

ABS Actuator Operation Check:

(d) Depress the Brake Pedal and hold it until step (g) is completed.
(e) Push the MAIN push switch, and check that the Brake Pedal does not go down.

CAUTION: Do not keep the MAIN push switch pushed down for more than 10 seconds.

(f) Release the switch, and check that the pedal goes down.

ABS Actuator Operation Check:

(g) Push and hold in the MOTOR switch for a few seconds, and check that the pedal returns.
(h) Release the Brake Pedal.
(i) Push and hold in the MOTOR switch for a few seconds.

ABS Actuator Operation Check:

(j) Depress the Brake Pedal and hold it for about 15 seconds As you hold the pedal down, push the MOTOR switch for a few seconds. Check that the Brake Pedal does not pulsate.
(k) Release the Brake Pedal.
(l) Turn the selector switch to "REAR RH" position.
(m) Repeat (c) to (j), checking the Actuator operation similarly.
(n) Similarly, inspect "REAR LH" and "FRONT RH" position.

ABS Actuator Checker Selector Switch Position:

NOTE: When inspecting "FRONT RH" position, push the FRONT RH switch instead of the MAIN push switch, and you can inspect in any selector switch position.
