Fail-Safe
INFOID:0000000010049146
CAUTION:
If the Fail-Safe function is activated, perform self-diagnosis for VDC/TCS/ABS system.
ABS, EBD SYSTEM
In case of an electrical malfunction with the ABS, ABS warning lamp and SLIP indicator lamp will turn on. In
case of an electrical malfunction with the EBD system, brake warning lamp, ABS warning lamp and SLIP indi-
cator lamp will turn on. The system will revert to one of the following conditions of the fail-safe function.
• For ABS malfunction, only the EBD is operative and the condition of vehicle is the same condition of vehicles
without VDC/TCS/ABS system.
• For EBD malfunction, the EBD and ABS become inoperative, and the condition of vehicle is the same as the
condition of vehicles without VDC/TCS/ABS or EBD system.
VDC / TCS
In case of VDC/TCS system malfunction, SLIP indicator lamp is turned on, and the condition of vehicle is the
same as the condition of vehicles without VDC/TCS system. In case of an electrical malfunction with the VDC/
TCS system, the ABS control continues to operate normally without VDC/TCS control.
