Slip Indicator Light Remains ON

BRAKE CONTROL: VEHICLE STABILITY CONTROL SYSTEM: Slip Indicator Light Remains ON
- Slip Indicator Light Remains ON

DESCRIPTION

The skid control ECU is connected to the combination meter via CAN communication.

Pressing the VSC OFF switch turns off traction control and pressing and holding this switch turns off traction and VSC controls. If traction control turns OFF, the SLIP indicator light will come on.

The SLIP indicator light blinks during VSC and/or TRAC operation.

When the system fails, the SLIP indicator light comes on to warn the driver Diagnosis System.

The SLIP indicator light comes on when traction control is terminated by pressing the VSC OFF switch.
