PROBLEM
The slide- out
functions normally
but the control pad
green indicator light
blinks.
The slide-out does not
extend.
CAUSE
Something is defective and
may eventually create an issue
if not repaired. The problem
may be:
A. Faulty limit sensor causing
the slide- out to stop
overcurrent;
B. CAN network
causing the transmission inhibit
safety to be non-operational;
C. Vacuum pressure transducer
disconnected or damaged
(vacuum is applied for a fixed
time of 7 seconds);
D. Seal inflating valve solenoid
open circuit (the seal is not re-
inflated and water can penetrate
in the vehicle);
E. Security pin valve solenoid
open circuit (the security pin is
not extended while vehicle is
riding).
The parking brake is not seen
by the controller as being
applied;
Not enough air pressure in the
accessory air tank to permit
proper operation of the vacuum
generator;
Faulty vacuum generator,
connection to the
generator open, seal deflating
valve solenoid open circuit;
I/O-B module output defective,
regulated 5- volt supply
sensors shorted to ground, "out
limit" sensor shorted to ground,
connection to the

circuit;

problem
Using the Driver Information Display (DID), request a
diagnostic of the electrical system.
Make sure the parking brake is applied. Confirm
parking brake application with the parking brake light
on the telltale panel.
Run the engine at fast idle a few minutes to increase
air pressure in the accessory air tank and try again.
Turn the relieving shut-off valve handle clockwise to
deflate the inflatable seal, disconnect the pressure
vacuum 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;

Operate the slide- out with the manual override
procedures.
