TERMINAL LAYOUT

Fail-Safe

INFOID:0000000009479537

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.

HILL DESCENT CONTROL/HILL START ASSIST SYSTEM

In case of hill descent control system malfunction, the hill descent control indicator lamp will remain off even

though the hill descent control switch is operated and the condition of the vehicle is the same as the condition

of vehicles without hill descent control system.

In case of hill start assist system malfunction, the VDC OFF and SLIP indicator lamps are turned on and the

condition of the vehicle is the same as the condition of vehicles without hill start assist 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.
