When using hand-held tester: CHECK SENSOR SIGNAL BY TEST MODE




a. Procedures for test mode:

1. Turn the ignition switch OFF.
2. Check that the shift lever is on P.
3. Connect the hand-held tester to the DLC3.
4. Start the engine.
5. Select the Test Mode following the hand-held tester screen.

HINT: Refer to the hand-held tester operator's manual for further details.

VSC warning lamp circuit

7. Start the engine.

b. Check the deceleration sensor.

1. Create gravitational force (0.2 G or more) on the vehicle through deceleration. Use one of the following methods to decelerate the vehicle in the direction it is moving:

- Apply the brake of a moving vehicle.
- Drive over a bump.
- Drive on an incline.

2. When the deceleration is 0.2 G or more, check that the ABS warning lamp illuminates.

c. Check the master cylinder pressure sensor.

1. Leave the vehicle in a stationary condition and the brake pedal released for 1 second or more.Then quickly depress the brake pedal with a force of 98 N (10 kgf, 22lbf) or more 1 second or more.

HINT: As this time, the ABS warning lamp turns on for 3 sec.

d. Check the speed sensor.




1. Drive the vehicle straight forward at following speed.Then check the ABS warning lamp.

HINT: The sensor signal check may not complete if the vehicle's wheels slip or its steering wheel is turned during this check.

2. Stop the vehicle.




e. Check the yaw rate sensor:

1. Move the shift lever to D and drive the vehicle at the vehicle speed of approximately 5 km/h (3 mph). Turn the steering wheel either to left or right 90 ° or more, and drive the vehicle in a half-circle pattern.
2. Stop the vehicle and move the shift lever to P. Check that the skid control buzzer sounds for 3 seconds. If the skid control buzzer sounds, the sensor check has completed normally. If the skid control buzzer does not sound, check the skid control buzzer circuit, and check the sensor again. If the skid control buzzer still does not sound, there is malfunction in the VSC sensor. Check the DTCs.

HINT:
- Drive the vehicle in a half-circle pattern. At the end of the turn, the direction of the vehicle should be within 180 ° + 5 ° from its start position.
- Do not spin the wheels.

3. Read the DTCs.
