ABS, EBD SYSTEM

If ABS malfunction electrically, ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp will turn on. If
EBD malfunction electrically, brake warning lamp, ABS warning lamp, VDC OFF indicator lamp and SLIP indi-
cator lamp will turn on. Simultaneously, the VDC/TCS/ABS become one of the following conditions of the fail-
safe function.

< ECU DIAGNOSIS >

[VDC/TCS/ABS]

ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT)

• For malfunction of ABS, only the EBD is activated and the condition of vehicle is the same condition of vehi-

cles without TCS/ABS system.
NOTE:
ABS self-diagnosis sound may be heard. That is a normal condition because a self-diagnosis for “Ignition
switch ON” and “The first starting” are being performed.

• For malfunction of EBD, EBD and ABS become inoperative, and the condition of vehicle is the same as the

condition of vehicles without TCS/ABS, EBD system.

VDC/TCS 

If VDC/TCS/ABS system malfunction electrically, VDC OFF indicator lamp, SLIP indicator lamp are turned on,
and the condition of vehicle is the same as the condition of vehicles without VDC/TCS control.

CAUTION:

If the Fail-Safe function is activated, then perform self-diagnosis for VDC/TCS/ABS control system.
