Traction Control Switch: Description and Operation

CIRCUIT OPERATION
The traction control system uses a switch that allows the operator to turn the system OFF. Circuit B27 is used as the input from the switch to the Controller Anti-Lock Brake (CAB). Ground for the switch is provided on circuit Z1.

When the switch is pressed a ground path is completed from the CAB, through the switch, to the Z1 ground circuit, and to ground.
