2.
To test the supply solenoid valve response, press
the TEST button (figure 11). The diagnostic focus
shifts from the warning lamp to the supply
solenoid valve.
Press the CH/SAVE (change / save) button to
toggle the supply solenoid valve from off to on.
Press the CH/SAVE button again to toggle the
valve from on to off (figure 11).
CAUTION:
Potential overinflation hazard. When
performing diagnostics, the trailer air
tank pressure MUST NOT be higher
than the target pressure setting.
If the trailer air tank pressure is
higher, the tires will overinflate when
both supply and delivery solenoid
valves are opened at the same time.
No method exists to exhaust the
overinflated tires, other than
disconnecting the tire hoses and
manually depressing the valve stem
core at each tire.
The supply solenoid valve will remain in the last
state chosen (either on or off) when the
diagnostic focus is changed in the next step.
3.
To test the delivery solenoid valve response,
press the TEST button (figure 12). The diagnostic
focus shifts from the supply solenoid valve to the
delivery solenoid valve.
Press the CH/SAVE button to toggle the delivery
solenoid valve from off to on. Press the CH/SAVE
button again to toggle the valve from on to off
(figure 12).
The delivery solenoid valve will remain in the last
state chosen (either on or off) when shifting to
another mode of operation.
When warning lamp and solenoid valve
response testing is complete, set all responses to
the OFF state and reconnect the wheel hose at
the tee fitting.
4.
Disconnect the hand-held programming device
or go to one of the other operational modes.
If you wish to disconnect the hand-held
programming device, refer to the disconnect
procedure on page 11 (the four-pin trailer power
cable must be the first one disconnected from the
hand-held programming device and the last one
connected to the controller assembly ECU).
If you wish to go to the target pressure setting
mode, press the +PSI or -PSI arrow on the
direction pad.
If you wish to go to the fault code history mode,
press the BACK FAULTS or FWD FAULTS arrow on
the direction pad.
