Circuit Description
Operation (ON/OFF) of ABS warning light is controlled by ABS control module through lamp driver module in
combination meter.
If the antilock brake system is in good condition, ABS control module turns ABS warning light ON at the ignition switch
ON, keeps it ON for 2 seconds and then turns it OFF. If an abnormality in the system is detected, ABS warning light is
turned ON continuously by ABS control module. Also, it is turned ON continuously by lamp driver module when the
connector of ABS control module is disconnected.
