VSC SENSOR CHECK (TEST MODE)

In case of not using hand-held tester

NOTE: When having replaced the yaw rate sensor, deceleration sensor and/or ECU, perform a zero point calibration of the yaw rate and deceleration sensors (See step 8.).

HINT: If the ignition switch is turned from the ON to the 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 is in the P position, and turn the steering wheel to the neutral position.
3. Using SST, connect terminals Ts and E1 of the DLC1.

4. Start the engine.




5. Check that the VSC TRAC warning light blinks.

HINT: If the VSC TRAC warning light does not blink, inspect the VSC TRAC warning light circuit and Ts terminal circuit.

Turn the steering wheel either to the left or right 450 ° or more from the vehicle stationary condition, and turn back the steering wheel to the straight ahead position.

b. Keep the vehicle stationary on a level place for 1 sec. or more.




c. Check the yaw rate sensor.
Shift the shift lever to the D position and drive the vehicle at a vehicle speed of approx. 5 km/h (3 mph), turn the steering wheel either to the left or right 90 ° or more, and maintain this angle until the vehicle has turned 180 °.

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

If the VSC buzzer sounds, the sensor check is in normal completion.
If the VSC buzzer does not sound, do the sensor check again.
If the VSC buzzer still does not sound, check the VSC buzzer circuit, then do the sensor check again.

HINT:
- Make a 180 ° turn. At the end of the turn, the direction of the vehicle should be within 180° ± 5° of its start position.
- Do not spin the wheels.

d. Read the DTC.
1. Using SST, connect terminals Tc and E1 of the DLC1 or Tc and CG of the DLC3.

2. Read the number of times the VSC TRAC warning light blinks.

HINT:
- See the list of DTC.
- If every sensor is normal, a normal code is output. (A cycle of 0.25 sec. ON and 0.25 sec. OFF is repeated.)
- If 2 or more malfunctions are indicated at the same time, the lowest numbered code will be displayed 1st.

3. After doing the check, disconnect the SST from terminals of the DLC1 or terminals of the DLC1 and DLC3 and turn the ignition switch OFF.
