door post forward.
Unlock the Bulkhead Door
A. Press and hold the FOB button
for one second and release. The
door will unlock once the button is
released.
B. From the inside the cargo area,
slide the latch away from the door.
Unlock the Rear Door
A. Press and release the FOB button
twice in succession.
B. From the cargo area, press the
unlock switch on the rear door.
C. From the cargo area, slide the latch
away from the door.

Use a digital or analog voltmeter to check power and voltage!
Do NOT use a test light
Trouble Shooting Guide - 1000 Series Remote Control
1.0 No output from one or
more outputs on receiver
when transmitter buttons
are pressed
1.1 No signal from transmitter
1.2 One or more of the outputs
have failed.
1.3 Receiver outputs OK, but
relays or equipment do not
operate.
1.4 Fuse is blown.
1.5 Wire harness problem
1.1.1 Verify that transmitter is sending a signal and that
transmitter is coded correctly. See Symptom 3.
1.2.1 Open receiver and observe yellow LEDs. The output LED
should turn ON as long as relay is ON.
1.2.2 Press each transmitter button in sequence. Using a volt
meter, check each output. There should be +12V present
anytime the corresponding transmitter button is pressed. If no
outputs, call factory for RMA number.
1.3.1 Check wire and equipment for problem.
1.4.1 Check the fuse in fuse block. If fuse is blown, replace it.
1.5.1 Check input wire harness connections on J2-6 and J2-7. If
no voltage, correct wiring.
Symptom Possible Cause
2.0 Receiver is ‘dead’.
Does not operate, no heart
beat LED.
2.1 Logic ground or power
connection to receiver has failed
2.2 Chassis ground connection has
failed
2.3 Receiver and / or
microprocessor has failed.
2.1.1 Check logic ground and logic power. Use a voltmeter
probe when checking voltage.
2.1.2 If either ground or power is not present, then locate failure
in wire harness and repair.
2.2.1 Check chassis ground connection, it should be clean and
tight, no paint on metal, an external tooth star washer should be
present, no rust or dirt in connection.
2.2.2 Chassis ground should be located on vehicle frame or
directly to battery.
2.31 Check yellow output LEDs. If they DO NOT flash each
time corresponding channel is activated, the receiver has failed.
Call factory to get RMA number.
2.3.2 Check heart beat LED. If it is not flashing, the
microprocessor has failed. Call factory to get RMA number.
Symptom Possible Cause Corrective Action
3.0 No signal (code) being
transmitted
3.1 Transmitter battery voltage
low
3.2 Transmitter code is incorrect
3.3 Not all buttons send a signal
when pressed.
3.1.1 Check battery voltage, should be 3.0 VDC. Replace
battery if voltage is 2.8 VDC or less. (Signal strength is
dependent upon battery voltage.) Transmitter LED does not turn
on if battery voltage is low.
3.2.1 If transmitter is sending a signal (LED turns ON) and no
signal is being received, re-enroll transmitter to receiver. If
unable to enroll transmitter, call factory for RMA number.
3.3.1 If a signal is not transmitted on all buttons, send back to
factory for repair or replacement.

4.0 Poor range 0’ to 25’
(pulsating 0’ to 25’) 4.1 Receiver installed in poor
location near motor, large bundle
of wires.
4.2 Receiver logic power input or
ground is exposed to radiated
noise from wire harness or motors
4.3 Poor ground connection
4.4 Transmitter 3-volt battery is
low
4.5 Interference
4.6 Receiver component damaged
or defective
4.7 Other equipment installed in
vehicle causing voltage drop when
initially turning on
4.1.1 Disconnect motor and recheck range.
4.1.2 If range is ok, then ‘electrical noise’ from motors is
causing interference with RF signal.
4.1.3 Move module a minimum of 6 feet from the
motors.
.
4.2.1 Disconnect receiver logic power input or logic ground
from main wire harness
4.2.2 Run new wire from vehicle battery to red wire.
4.2.3 Remove black wire on receiver from vehicle wire harness
and install on the vehicle frame for a new chassis ground or
battery ground.
4.3.1 Remove any paint or residue from metal, use an external
tooth star washer and tighten new chassis ground terminal
securely to vehicle frame.
4.4.1 Replace battery if voltage is 2.8 volts or below
(All transmitters use: Lithium Coin Style - #CR2032)
4.5.1 Electromagnetic interference (EMI) can be generated by
motors, welding equipment, relays, RF from other radio
frequency devices, etc. which may be in close proximity to the
receiver or transmitter.
4.5.2 Move closer to module or move vehicle out of range of
EMI caused by high levels of radio frequency from devices such
as welding equipment, as this is a temporary problem.
4.5.3 If EMI is caused by relays, door motors or lift motors then
the receiver must be moved or shielded or the EMI noise
diverted to ground. Call the factory for details.
4.6.1 Call factory for RMA number and return unit for repair.
4.7.1 Remove all other equipment from logic ground and power.
Check range. If ok, run power & ground directly from battery.
