TCS/DSC INDICATOR LIGHT

id041500108900


Purpose/Function

•  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.)
―  Roll over mitigation (ROM) is operating.
―  Trailer Stability Assist (TSA) is operating.
―  DSC system malfunction.

Operation

1.  The instrument cluster receives (1) the system condition display request signal from the DSC HU/CM via CAN communication.

2.  The instrument cluster turns the transistor on, or turns it on intermittently (2) based on the system condition display request signal.

3.  When the transistor turns on, the brake system warning lights/ABS warning light turns on or flashes (3).

•  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 to ON to check the light function. When the system is malfunctioning, the TCS/DSC indicator light remains illuminated.
•  When the TCS, DSC or roll over mitigation (ROM) are non-operational, operational and malfunctioning, the TCS/DSC indicator light operates according to the following table.
