TCS OFF SWITCH, TCS OFF INDICATOR LIGHT
id041500108700
Purpose
• The TCS OFF switch, located on the dashboard, allows for optionally enabling/disabling the TCS control at driver discretion.
• The TCS OFF indicator light, built into the instrument cluster, informs the driver that TCS control has been disabled by operation of the TCS OFF switch.
Functions
• The TCS OFF switch sends a switch operation signal to the instrument cluster.
• The TCS OFF indicator light and the TCS OFF switch indicator light turn on when the LDWS OFF switch is on.
Operation
TCS OFF switch
-
1. When the TCS OFF switch is operated, the TCS OFF switch operation signal is sent (1) to the instrument cluster.
2. Based on the switch operation signal (detected voltage value), the instrument cluster sends (2) the TCS OFF switch operation signal to the DSC HU/CM via CAN communication.
3. When DSC HU/CM receives the TCS OFF switch operation signal from the instrument cluster, it switches (3) the TCS to operational or non-operational.
4. The instrument cluster turns on (4) the transistor when the TCS OFF switch is on.
5. When the transistor turns on, a ground circuit with the indicator light is established, and the indicator light turns on (5).
TCS OFF indicator light
-
• When the DSC system and CAN lines are functionally normally, the TCS OFF indicator light illuminates for approx. 3.0 s when the ignition is switched to ON to check the light function.
• When the TCS OFF switch is pressed to disable TCS control, the TCS OFF indicator light and the TCS OFF switch indicator light turn on.
• Press the switch again to turn the TCS back on. The TCS OFF indicator light and TCS OFF switch indicator light will turn off.
-
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.
