ATC Components
ATC may be used with individual ABS modulator valves, or installed
with the ABS valve package.
When installed with individual ABS modulator valves, an ATC
solenoid valve is mounted on the frame or cross member, near the
rear of the vehicle.
When it is part of the ABS valve package, an ATC valve is attached
to the relay valve.
A cable connects the ECU to the ATC valve.
ATC components are illustrated in Figure 2.3.
Figure 2.3
Deep Snow and Mud Switch
A deep snow and mud option switch is included with ATC. This
function increases available traction on extra soft surfaces like
snow, mud or gravel, by slightly increasing the permissible
wheel spin.
Drivers use a deep snow and mud switch to select this feature.
When this function is in use, the ATC indicator lamp blinks
continuously. Figure 2.4.
Figure 2.4
Switch and lamp locations will vary, depending on the vehicle make
and model.
Here’s how the deep snow and mud feature works.
NOTE: Turning off the ignition will also deactivate the deep snow
and mud feature.
