SYMPTOM
T
The electric door begins to move but stops or reverses direction.
The electric door closes all the way but then opens on it’s own.
The sensitive edge does not work or is not sensitive enough.
The step well light does not operate.
All of the outputs are on regardless of switch position.
This is a very specific symptom. The key word above is “All”. When this happens it usually means that
somewhere in the system, the communications wire, pin 2 on a 3 pin plug, is being shorted to ground. In
the past we have found a screw driven through wires shorting it to ground as well as defective modules
causing the problem. To isolate this, begin by disconnecting all of the 3 pin plugs from the master. If when
you do this, all of the outputs turn off, begin connecting the 3 pin plugs one at a time until the lights come
on again. When they do, you have identified the circuit responsible for the problem. Disconnect the 3 pin
plug from the module on the other end of this circuit. If the system returns to normal, you have a bad
module. If it does not, you may have a short to ground in your harness.

. Check the fuse located on the master module. Power to run the door comes from the master via this
fuse.
. Unplug the three pin plug from the door module 00-00787. This part of the harness should go back to J4
or J5 at the master. Check multiplex communications on the harness by measuring the voltage between
pins 2 and 3. You should measure 6.5-9 volts. Check between pins 1 and 3. You should measure
battery voltage. If these check out the harness is ok.
If there is an exterior key switch, check to make sure that it is not in the close position. When the door
is closed via the exterior switch, the interior switch is disabled.
. Check the jumper settings in the door module and the dip switch settings at the switch adapter. If the
switch adapter is set for “A”, the door module must also be set for “A” (See the module page to
determine how to set the jumpers.).
Make sure that power ground is connected to pin 8 on the 8 pin connector of the door module
Try replacing the door module. Make certain that the module jumpers are configured properly.
Check to see if there is an obstruction in the path of the door or a mechanical problem that impedes the
movement of the door mechanism.
. The sensitivity setting on the door module may be set too sensitive. See the door module page in this
manual for proper setting.
In the path of the door mechanism there should be a switch that closes when the door is very close to
being closed. This switch should be connected to the door closed inputs on the door module. The sole
purpose of this switch is to defeat the sensitive edge when the door is nearly closed to allow the door to
seal closed. This problem will occur if this switch is missing, defective or misadjusted.
Refer to the door module page 10 in this manual for sensitive edge settings
1. The step well light output on the door module is on a voltage sensor. If the voltage is too low the light
will turn off. Check the battery voltage. Check the bulb.
