NOTE:
  • Even though the ABS warning light does not go out after 1.5 seconds from ABS warning light illumination, the ABS system operates normally when the warning light goes out while driving at approximately 12 km/h (7.46 MPH). However, the ABS does not work while the ABS warning light is illuminated.
  • When the vehicle is parked in a lower temperature place for long time, VDC warning light/VDC OFF indicator light may takes few minutes to go off. This is not defective because it is resulted from low engine coolant temperature.
  • One of the wheels is locked or slipped, power train to the other wheel may changes. Changing of power train may difference in occurring normal operation. This situation detect by ABS wheel speed sensor. ABS warning light and VDC warning light come on. When the vehicle is driven in all four wheels off from ground, or all four wheels on the free roller, VDCCM detect the malfunction of speed sensor and ABS warning light and VDC warning light may illuminate. In this case, this is not a malfunction. Erase the DTC from memory.
