When not using hand-held tester: CHECK SENSOR SIGNAL BY TEST MODE




a. Procedures for test mode:

1. Turn the ignition switch OFF.
2. Using SST, connect terminals 12 (TS) and 4 (CG) of DLC3.

SST 09843-18040

3. Check that the steering wheel is in the straight- ahead position and move the shift lever to P.
4. Turn the ignition switch ON.




5. Check that the ABS warning lamp or VSC warning lamp blinks as shown in illustration.

HINT: If no code appears, check the TC circuit, ABS warning lamp circuit or VSC warning lamp circuit.

Trouble Area
TC terminal circuit
ABS warning lamp circuit
VSC warning lamp circuit

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 brakes 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, 22 lbf)or more for 1 second or more.

HINT: At this time, the ABS warning lamp turned on for 3 seconds.

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. Read the DTCs.

1. Using SST, connect terminals 12 (TS) and 4 (CG) of the DLC3.

SST 09843-18040

2. Read the number of blinks of the ABS warning lamp.

HINT:
- As an example, the blinking patterns for trouble codes 72 and 76 are shown.
- Condition are explained in Diagnostic Trouble Code chart.
- For the normal code, the lamp cycles between ON and OFF at intervals of 0.25 seconds.
- If more than 1 DTC is detected at the same time, the lowest numbered code will be displayed first.




3. After the check, disconnect the SST from terminals 12 (TS) and 4 (CG) of the DLC3.




f. 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.




g. Read the DTCs.

1. Using SST, connect terminals 12 (TS) and 4 (CG) of the DLC3.

SST 09843-18040

2. Read the number of blinks of the VSC warning lamp.

HINT:
- As an example, the blinking patterns for trouble codes 72 and 76 are shown.
- Condition are explained in Diagnostic Trouble Code chart
- For the normal code, the lamp cycles between ON and OFF at intervals of 0.25 seconds.
- If more than 1 DTC is detected at the same time, the lowest numbered code will be displayed first.




3. After the check, disconnect the SST from terminals 12 (TS) and 4 (CG) of the DLC3.
