• 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 “ABS” with CONSULT-III.

LDW/LDP SYSTEM

• In case of malfunction in the LDW/LDP system, lane departure warning lamp is turned ON, and the condition

of vehicle is the same as the condition of vehicles without LDW/LDP control.

• In case of malfunction in the VDC/TCS/ABS system, lane departure warning lamp is turned ON, and the

condition of vehicle is the same as the condition of vehicles without LDW/LDP control.
