ON/OFF switch

This switch is of spring-loaded type and makes contact only when the button is pressed. By pressing the button a pulse is sent to the control module which causes it to either engage or disengage the TCS system. Accordingly, it is not possible to see whether the system is manually engaged or disengaged just by looking at the position of the button. This can be verified by looking at the TCS OFF lamp.

The ON/OFF switch can be used to switch off the system at speeds lower than 60 km/h or to engage the system at any speed.

The TCS switch has two connections, one to pin 1 of the control moodule and the other to ground. When the button is pressed, the circuit closes and the system is either engaged or disengaged, depending on its status.

If the circuit to pin 1 of the control module is shorted to ground, a diagnostic trouble code will be generated and the system cannot be disengaged. The same trouble code will also be generated if the TCS switch is pressed continuously for more than 10 seconds.

The system is always engaged in connection with starting when the ignition switch is turned to the Drive position.
