Trouble Code Clearance" in this section.
Also ABS control module turns ON EBD warning lamp (brake warn-
ing lamp) depending on the trouble that detected by the module
and EBD warning lamp does not indicate DTC as well as "ABS"
warning lamp.
Fail-Safe Function
When an abnormality occurs (an abnormal DTC is detected), ABS
control module turns OFF the fail-safe relay which supplies power
to ABS hydraulic unit. Thus, with ABS not operating, brakes func-
tion just like the brake system of the vehicle not equipped with ABS.
