PVG Valves are being operated manually.

The auto tailgate release will not function when the PVG Valves are operated
manually.

It is not recommended to operate the system in this way due to safety issues.

Manual operation is only recommended for system troubleshooting or as
a last resort because of a system failure.

Tailgate and height sensors are no longer working.

Locate tailgate and height proximity sensors and enable the system following the

steps in Section 2.2.1.

All three sensors will remain illuminated when in range of a ferrous metal object

and turn off when not. Verify that all are working properly. When the dump
body is lowered, the two height sensors will be illuminated. When the tailgate

has been released the tailgate sensor will become illuminated.

•

If the sensors do not respond when tested, see the electrical
troubleshooting in Section 3.4.9. Reference drawing 20754 in Section 7.

Tailgate and height sensors have moved from the original position.

Lift the dump body using the joystick or remote, see Section 2.2 or 2.3. When

the body reaches 22° one of the height sensors should turnoff and the tailgate
should release.

The other sensor should turn off at approximately 40°. If this does not happen
for either of the sensors they may have moved during operation and require

repositioning.

If these sensors are being repositioned, ensure the body does not contact any
part of the truck when raised. Do not overextend the hoist cylinder.
