With Lexus Hand-Held Tester

Check the VSC sensor signal.




1. Hook up the LEXUS hand-held tester to the DLC3.
2. Check that the shift lever position is at P range, turn the steering wheel to the neutral position.
3. Start the engine and check that the "VSC TEST" displays on the multi-information display.
4. (After the battery terminal cable is connected, the first time only):
Check the zero point calibration of the yaw rate sensor.
Start the engine and keep the vehicle in the stationary condition on the flat place for 3 sec. or more.

HINT: If the "VSC TEST" does not display on the multi-information display, inspect the VSC warning indicator circuit and Ts terminal circuit.




5. Check the steering angle sensor.
Turn the steering wheel either to left or right for 450 or more from the vehicle stationary condition, and turn back the steering wheel to the straight ahead position.




6. Check the yaw rate sensor.
Shift the shift lever to the D range and drive the vehicle at the vehicle speed about 5kph (3 mph), turn the steering wheel either to left or right for 900 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 buzzer sounds for 3 seconds.

- If the VSC buzzer sounded, the sensor check is in normal completion.
- If the VSC buzzer does not sound, do the sensor check again.
- If the VSC buzzer still won't sound, there is malfunction in the VSC sensor, so check the DTC.

HINT:
- The vehicle direction should be within 1800° ± 5° at the time of the circular drive start and end positions.
- Do not spin the rear wheels.

7. Read the DTC by following the prompts on the tester screen.

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