Without Scan Tool

In case of not using the hand-held tester:
VSC SENSOR SIGNAL CHECK (TEST MODE)

NOTE: When having replaced the yaw rate sensor, deceleration sensor and/or ECU, perform zero point calibration of the yaw rate and deceleration sensors (See step 7.).

HINT: If the ignition switch is turned from ON to ACC or LOCK during test mode, DTC will be erased.

a. Procedures for test mode:
1. Turn the ignition switch OFF.
2. Check that the shift lever position is at P range. Turn the steering wheel to the straight-ahead position.




3. Using SST, connect terminals Ts and CG of DLC3.

4. Start the engine.




5. Check that the VSC warning light blinks.




b. Check the yaw rate sensor.
Shift the shift lever to the D range and drive the vehicle at the vehicle speed of approx. 5 km/h (3 mph). Turn the steering wheel either to left or right for 90° or more, and maintain 180° circular drive for the vehicle.

Stop the vehicle and shift the shift lever to the P range. Check that the VSC warning buzzer sounds for 3 sec.

If the VSC warning buzzer sounds, the sensor check is in normal completion.

If the VSC warning buzzer does not sound, check the VSC warning buzzer circuit, then do the sensor check again.

Trouble Area
warning buzzer circuit

If the VSC warning buzzer still does not sound, there is malfunction in the VSC sensor, so check the DTC.

HINT:
- Drive the vehicle circularly by 180°. 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.

1. Check the steering angle sensor.
Turn the steering wheel to either left or right to the full lock position, from the vehicle stationary condition, and turn back the steering wheel to the neutral position.

c. Read the DTC.




1. Using SST, connect terminals Tc and CG of DLC3.

2. Using SST, connect terminals Tc and CG of DLC3.

3. Read the number of blinks of the VSC warning light.

HINT:
- See the list of DTC shown.
- If every sensor is normal, a normal code is output. (A cycle of 0.25 sec. ON and 0.25 sec. OFF is repeated.)

4. After doing the check, disconnect the SST from terminals Ts and CG ,Tc and CG of DLC3 and turn the ignition switch OFF.
