id041500105500
Purpose/Function
• The DSC OFF switch, located on the dashboard, allows for optionally enabling/disabling the TCS/DSC control at driver discretion.
• The DSC OFF indicator light, built into the instrument cluster, informs the driver that TCS/DSC control has been disabled by operation of the DSC OFF switch.
Operation
• When the DSC system and CAN lines are functionally normally, the DSC OFF indicator light illuminates for approx. 3.0 s when the ignition is switched ON to check the light function.
• When the DSC OFF switch is pressed to disable TCS/DSC control, the DSC OFF indicator light illuminates.
• The DSC OFF indicator light illumination and TCS/DSC control conditions while operating the DSC OFF switch are as indicated in the table.

Note
-
• The smart city brake support (SCBS) system will operate even if the DSC OFF indicator light is illuminated after the DSC is stopped by operating the DSC OFF switch. If the smart city brake support (SCBS) system operates while the DSC has been stopped, the DSC becomes operational and the DSC OFF indicator light turns off.
