Section 26: XLII SLIDE-OUT
PA1564 42
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
A. The security pin valve solenoid circuit
is shorted to (+) 24-volt and the pin
remains engaged;
A. 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-out 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.
