The TCS/DSC indicator light, built into the instrument cluster, informs the driver of the following vehicle conditions.
TCS is operating. (Drive wheel is slipping.)
DSC is operating. (Vehicle side-slip condition.)

When the DSC system and CAN lines are normal, the TCS/DSC indicator light illuminates for approx. 3.0 s when the ignition is switched ON to check the light function. When the system is malfunctioning, the TCS/DSC indicator light remains illuminated.
When the TCS or DSC are non-operational, operational and malfunctioning, the TCS/DSC indicator light operates according to the following table.
