Suzuki Liana RH413, Service Manual

Page: 505 / 1302

ABS: 4E-3
• When diag. switch terminal (2) of diagnosis connector
(1) (monitor connector) is grounded, the abnormal
area is output as DTC. It is indicated by flashing of
ABS warning lamp. (Refer to the following table.)
• For procedure to clear all DTCs, refer to “DTC
Clearance”.
Also ABS control module turns ON EBD warning lamp
(brake warning lamp) depending on the trouble and EBD
warning lamp does not indicate DTC.
Fail-Safe Function
When an abnormality occurs (an abnormal DTC is
detected), ABS control module turns OFF the fail-safe
relay (transistor) which supplies power to it self. Thus,
with ABS not operating, brakes function just like the
brake system of the vehicle without ABS.
