• 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.

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.
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.
