TCS OFF SWITCH, TCS OFF INDICATOR LIGHT
id041500108700
Purpose
• The TCS OFF switch allows for optionally enabling/disabling the TCS control at the driver's discretion.
• The TCS OFF indicator light notifies the driver that TCS control has been disabled by operation of the TCS OFF switch.
Function
• The TCS OFF switch sends a switch operation signal to the instrument cluster.
• The instrument cluster turns on the TCS OFF indicator light based on the system condition display request signal sent via CAN communication from the TCS HU/CM.
• The TCS OFF indicator light illumination and TCS/DSC control conditions while operating the TCS OFF switch are as indicated in the table.
• When the DSC system and CAN lines are functioning normally, the TCS OFF indicator light turns on for approx. 3 s when the ignition is switched ON.
• When the TCS OFF switch is pressed to disable the TCS control, the TCS OFF indicator light turns on.
-
Note
-
• To inhibit the TCS control, continue to press the TCS OFF switch until the TCS OFF indicator light illuminates.
• The TCS OFF indicator light illumination and TCS/DSC/roll over mitigation (ROM) control conditions while operating the TCS OFF switch are as indicated in the table.

Construction
• The TCS OFF switch is located on the dashboard (cluster switch).
• The TCS OFF indicator light is built into the instrument cluster.

Operation
TCS OFF switch
1. When the TCS OFF switch is operated, a switch operation signal is sent (1) to the instrument cluster.
2. Based on the switch operation signal (voltage value), the instrument cluster sends (2) the TCS OFF switch operation signal to the DSC HU/CM via CAN communication.
3. The DSC HU/CM switches (3) the TCS ON/OFF when it receives the TCS OFF switch operation signal from the instrument cluster.
TCS OFF indicator
1. The instrument cluster receives (1) the system conditions display request signal from the DSC HU/CM via CAN communication.
2. The instrument cluster turns the transistor on (2) based on the system condition display request signal.
3. When the transistor turns on, the TCS OFF indicator light turns on (3).

• When the DSC system and CAN lines are functioning normally, the TCS OFF indicator light turns on for approx. 3 s when the ignition is switched ON.
• When the TCS OFF switch is pressed to disable the TCS control, the TCS OFF indicator light turns on.
