In this model, the ABS indicator light (LED) [A] and KIBS indicator light (LED) [B] go on or blink by the data sent from the KIBS hydraulic unit.

ABS and KIBS Indicator Lights (LED) Function

*: The mode of “Low voltage ABS” controls ABS while reducing the load to the battery.
NOTE
When the ABS indicator light is blinking, the ABS has been in the low voltage mode (insufficient battery voltage).
When it is in the low voltage mode, the KIBS system does not function, but the ABS functions. To recover the KIBS system, charge the battery. (see Refreshing Charge in the Electrical System chapter).
