TCS Switch LED

TCS SWITCH LED
Whenever the TCS switch LED is illuminated TCS is available. This will default ON every time the vehicle is started. The TCS can be disabled by pressing the switch.
When the electronic brake and traction control module is in diagnostic mode (Scan tool corrected), the TCS LED will be turned Off by the EBTCM.

IMPORTANT: Clear DTCs before performing any special tests with Scan tool.
