"◦" in ABS warning light, EBD warning light and ESP® warning light columns of the above table means warning light is lit when DTC is detected.
(1) If two or more wheel speed sensor are defective, ABS warning light, EBD warning light and ESP® warning light are lit and all the control functions are deactivated. If one wheel speed sensor is defective, ABS warning light and ESP® warning light are lit and ABS and traction control system/stability control system are deactivated.
(2) For 4WD vehicle, ABS warning light and ESP® warning light are lit and ABS and traction control system/stability control system are deactivated. For 2WD vehicle, ESP® warning light is lit and traction control system/stability control system is deactivated.
(3) SLIP indicator light, ESP® OFF light and hill descent control indicator light (if equipped) turn ON when power supply circuit voltage is low.
(4) SLIP indicator light flashes continuously at Intervals of 1 Hz.
(5) EBD warning light is lit when power supply circuit voltage is too low.
(6) For hill descent control model.
