ABS ACTUATOR INSTALLATION

Installation is in the reverse order of removal.

After installation, fill brake reservoir with brake fluid, bleed brake system and check for leaks. Service and Repair

ABS ACTUATOR INSPECTION

NOTE: Using the ABS actuator checker (SST), check the operation of the actuator. If the actuator does not operate. check the operation of sub-wire harness G according to instructions. If the solenoid and/or pump motor Relay are abnormal, replace the relay and inspect the actuator operation again.

1. Inspect battery positive voltage.
Battery positive voltage: 10-14 Volts.

Actuator Connectors (w/o TRAC):

2. Disconnect 2 connectors from actuator.

Connect Actuator Checker (SST) To Actuator:

3. Connect actuator checker (SST) to actuator.
(a) Connect the actuator checker (SST) to the actuator side wire harnesses via the sub-wire harnesses (SST) as shown.
SST 09990-00150. 09990-00210. 09990-00250. 09990-00280
(b) Connect the red cable of the checker to the battery positive (+) terminal and the black cable to the negative (-) terminal. Connect the black cable of the sub-wire harnesses to the battery negative (-) terminal or body ground.
4. Inspect brake actuator operation.
(a) Start the engine, and run it at idle speed.

Inspect Brake Actuator Operation, Using Actuator Checker:

(b) Turn the MAIN selector switch of the actuator checker to the "FRONT RH" position.
(c) Push and hold in the SUB MOTOR switch for a few seconds.
(d) Depress the Brake Pedal and hold it until step (g) is completed.

Brake Actuator Operation Inspection:

(e) Push the MAIN push switch and check that the Brake Pedal cannot be depressed.

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

(f) Release the switch, and check that the pedal can be depressed.

Brake Actuator Operation Inspection:

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

Brake Actuator Operation Inspection:

(i) Push and hold in the SUB MOTOR switch for a few seconds.
(j) Depress the Brake Pedal and hold it for about 15 seconds. As you hold the pedal down, push the SUB MOTOR switch for a few seconds. Check that the Brake Pedal does not pulsate.
5. Inspect for other wheels.
(a) Turn the MAIN selector switch to the "FRONT LH" position.
(b) Repeat (c) to (j) of step 4, checking the actuator operation in the same way.
(c) Also, inspect the "REAR" position following the same procedure.
6. Push and hold in the SUB MOTOR switch for a few seconds.
7. Disconnect actuator checker (SST) from actuator.
(a) Disconnect the actuator checker (SST) and sub-wire harnesses (SST) from the actuator.
SST 09990-00150, 09990-00210, 09990-00250, 09990-00280

Connect The Actuator Connectors:

(b) Connect the actuator connectors.
(c) Clear the DTC.
