Toyota Yaris: Brake Actuator / On-vehicle Inspection
ON-VEHICLE INSPECTION
PROCEDURE
1. CONNECT GTS
(a) Connect the GTS to the DLC3 with the engine switch off.
(b) Start the engine and run it at idle.
(c) Turn the GTS on.
(d) Enter the following menus: Chassis / Brake/EPB / Active Test.
HINT:
Refer to the GTS operator's manual for further details.
2. INSPECT ACTUATOR MOTOR OPERATION
(a) Enter the following menus: Chassis / Brake / Active Test / Motor Relay.
Chassis > Brake > Active Test| Tester Display |
|---|
| Motor Relay |
(b) Turn the motor relay on and check for actuator motor operation sounds.
NOTICE:
Do not keep the motor relay on continuously for more than 5 seconds. If it needs to be operated repeatedly, wait an interval of more than 20 seconds between operations.
(c) Turn the motor relay off.
(d) Fully depress the brake pedal and hold it for approximately 15 seconds. Check that the initial brake pedal depth is maintained for the entire 15 seconds.
(e) Turn the motor relay on and check that the brake pedal does not pulsate.
NOTICE:
Do not keep the motor relay on continuously for more than 5 seconds. If it needs to be operated repeatedly, wait an interval of more than 20 seconds between operations.
(f) Turn the motor relay off and release the brake pedal.
3. INSPECT FRONT RIGHT WHEEL OPERATION
(a) Enter the following menus: Chassis / Brake / Active Test / ABS Solenoid.
Chassis > Brake > Active Test| Tester Display |
|---|
| ABS Solenoid |
(b) Depress the brake pedal and hold it.
NOTICE:
Do not turn on a solenoid in a manner different than that shown in the following steps.
(c) Turn the SFRH and SFRR solenoids on simultaneously and check that the brake pedal cannot be depressed further.
NOTICE:
Each solenoid operates for 2 seconds and turns off automatically. If a solenoid needs to be operated repeatedly, wait an interval of more than 20 seconds between operations.
(d) Turn the SFRH and SFRR solenoids off simultaneously and check that the brake pedal can be depressed.
(e) With the brake pedal still depressed, turn the motor relay on and check that the brake pedal rises.
Chassis > Brake > Active Test| Tester Display |
|---|
| Motor Relay |
NOTICE:
Do not keep the motor relay on continuously for more than 5 seconds. If it needs to be operated repeatedly, wait an interval of more than 20 seconds between operations.
(f) Turn the motor relay off and release the brake pedal.
4. INSPECT OTHER WHEEL OPERATION
(a) Using the same procedure, check the solenoids for the other wheels.
HINT:
- Front left wheel: SFLH, SFLR
- Rear right wheel: SRRH, SRRR
- Rear left wheel: SRLH, SRLR

Front Seat Belt Pretensioners
The front seat belt pretensioners are designed to deploy in moderate or severe frontal, near frontal collisions.
In addition, the pretensioners operate when a side collision or a rollover accident is detected. The pretensioners operate differently depending on what types of air bags are equipped. For more details about the seat belt pretensioner operation, refer to the SRS Air Bag Deployment Criteria.
