PROBLEM CAUSE CORRECTIVE ACTION
The slide-out
does not
extend A. The parking brake is not seen by the controller
as being applied;
B. Not enough air pressure in the accessory air
tank to permit proper operation of the vacuum
generator;
C. Faulty vacuum generator, connection to the
vacuum generator open, seal deflating valve
solenoid open circuit;
D. I/O-B module output defective, regulated 5-volt
supply to sensors shorted to ground, “out limit”
sensor shorted to ground, connection to the
motor negative relay solenoid open circuit;
A. Make sure the parking brake is
applied. Confirm parking brake
application with the parking brake
light on the telltale panel.
B. Run the engine at fast idle a few
minutes to increase air pressure in
the accessory air tank and try again.
C. Turn the relieving shut-off valve
handle clockwise to deflate the
inflatable seal, disconnect the
pressure transducer. Do not forget to
reconnect the pressure transducer
and to close the relieving shut-off
valve. Failure to do so could damage
the seal and lead to water infiltration;
D. Operate the slide-out with the manual
override procedures.
The slide-out
does not
retract A. Not enough air pressure in the accessory air
tank to permit proper operation of the vacuum
generator;
B. Faulty vacuum generator, connection to the
vacuum generator open, seal deflating valve
solenoid open circuit;
C. I/O-B module output defective, “in limit” sensor
shorted to ground, connection to the motor
positive relay solenoid open circuit;
A. Run the engine at fast idle a few
minutes to increase air pressure in
the accessory air tank and try again.
B. Turn the relieving shut-off valve
handle clockwise to deflate the
inflatable seal, disconnect the
pressure transducer. CAUTION, do
not forget to reconnect the pressure
transducer and to close the relieving
shut-off valve. Failure to do so could
damage the seal and lead to water
infiltration;
C. Operate the slide-out with the manual
override procedures.
When
extending, the
slide-out stops
after having
extended by 1
inch The security pin valve solenoid circuit is shorted to
(+) 24-volt and the pin remains engaged; Disconnect air supply from the safety pin
cylinder;
Transmission
DRIVE range
or REVERSE
cannot be
selected (the
slide-out
telltale light is
illuminating). A. Slide-out not in full "in" position;
B. Faulty “in limit” sensor. The slide-out is
retracted but the controller doesn’t not see it
as retracted.
A. Retract slide-out.
B. Confirm that all slide-outs are
retracted. On the slide-out control
panel, disconnect the 5 pins green
connector on the I/O-B module to
disable the transmission inhibit.
CAUTION, this is a temporary
measure, the vehicle must be
serviced as soon as possible.
