ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT)

Fail-Safe

INFOID:0000000009479361

CAUTION:

If the Fail-Safe function is activated, perform Self Diagnosis for ABS/TCS/VDC system.

ABS/EBD SYSTEM

In case of an electrical malfunction with the ABS, the ABS warning lamp, VDC OFF indicator lamp and SLIP

indicator lamp will turn on. In case of an electrical malfunction with the EBD system, the BRAKE warning lamp,

ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp will turn on.

The system will revert to one of the following conditions of the Fail-Safe function.
1. For ABS malfunction, only the EBD is operative and the condition of the vehicle is the same condition of

vehicles without ABS/TCS/VDC system.

2. For EBD malfunction, the EBD and ABS become inoperative, and the condition of the vehicle is the same

as the condition of vehicles without ABS/TCS/VDC or EBD system.

VDC/TCS SYSTEM

In case of TCS/VDC system malfunction, the VDC OFF indicator lamp and SLIP indicator lamp are turned on

and the condition of the vehicle is the same as the condition of vehicles without TCS/VDC system. In case of

an electrical malfunction with the TCS/VDC system, the ABS control continues to operate normally without

TCS/VDC control.
