PowerBoard ® – Installation Instructions
Rev. T 0713 75113 pg. 11
Issue:
• Possible cause
Boards do not operate:
• Connected to incorrect vehicle wire
• Wire connections not secure
• Fuse burned
• Diodes reversed or damaged
• Factory door-ajar circuit inoperable
Board creaks or squeaks during operation:
• Gear shaft wedge bolt is loose
• Loosen mounting bracket and board
attachment screws. Adjust linkages so they
are parallel to each other and the noise is
gone. Tighten all fasteners.
PowerBoard ® Troubleshooting
Confirming PowerBoard ® is functional-black
controller:
To test if the black controller (460.91), wire harness,
motor and lights work, hook up to battery and touch
any of the 4 door trigger wires to ground. The board
for that side should go down and the lights should turn
on. The board should go up and the lights should turn
off when the wire is removed from ground.
Boards don’t operate correctly when connected
to wires identified in instructions:
Unfortunately vehicle manufactures do not
consistently keep the same wire colors in their wire
harnesses. The PowerBoard
® trigger wires need to be
connected the factory door-ajar wire that is connected
to each door latch switch. The correct wire is likely in
the same bundle that is identified in the instructions. If
PowerBoard ® Service Tips
Intermittent operation:
• Wire connections not secure
• Faulty diode or connection
• Bad ground
• Bad battery connection
Boards operate randomly:
• Wire connections not secure
• Diodes reversed or damaged
• Connected to incorrect vehicle wire
Board stays down all the time and can be
moved by hand:
• Gear shaft wedge screw is missing or loose
Board shakes and or shutters during operation:
• Bad ground
• Wire connections not secure
• Bad battery connection
One or more doors operate the board and other
do not:
• Wire connections not secure
• Diodes reversed or damaged
Delay in board operation or boards operate after
doors are shut:
• Diodes reversed or damaged
Board Hits Body:
• Install supplied PSA bumper per the
installation instructions
none of them work you can locate the correct wire
by removing the door panel and tracing the wire
bundle that leads to the door latch.
Use an ohm meter or continuity tester to find the door-
ajar wire on PowerBoards
® with black controllers.
The correct wire will go from neutral to ground when
the door is opened and return to neutral when the
door is shut. Connect one test lead to the negative
battery terminal and probe the wires with the other
lead. You can use a pin or a Posi-Tap connector
to pierce the wire insulation. The correct wire will
make the tester go from no continuity to complete
continuity when the door opened and return to no
continuity when the door is shut. You can also shut
the door latch with the door open by pushing on the
latch catch with a screw driver.
Checking Diodes:
If a diode is faulty or installed backwards, the system
will not receive necessary signal to deploy the step.
Diodes transmit current in only one direction. To test,
disconnect the diode from the system. The diode will
have a silver stripe on one end. Connect the side of
the diode without the stripe to positive twelve volts.
Connect the end with the stripe to a tester and ground
the tester. Current should flow through the diode in
this direction. There should be no current flow when
the end with the stripe is connected to positive twelve
volts. The diode is bad if current flows in this direction
or there is no current flow in either direction.
