Step With Control Unit
1. After the installation is complete and with the entrance door open, turn the override switch to the
'OFF' position.
NOTE: Some steps are not equipped with an override switch. They are activated only with a door switch.
2. Close the door. The step should retract and lock in the ‘up’ position.
3. Open the door. The step should extend and lock in the ‘down’ position with the under-step light
illuminated.
NOTE: The under-step light operation is as follows:
A. The light is ‘on’ when the step is extended
B. The light is ‘off’ when the step is retracted
C. In the event the coach door/screen door is left open, the light will turn ‘off’ after five minutes.
4. If your step is equipped with an override switch, turn it to the 'ON' position. The step should remain in
the extended position with the under step light 'OFF' when the door is closed.
5. With the step override switch turned 'ON', the step extended, and the entrance door closed, turn the
vehicle ignition on. The ignition override system will go into effect and steps automatically retract.
NOTE: If the yellow wire from the 4-way connector is not connected to an ignition power source, the
ignition safety system will be inoperative and the step will remain in the extended position. In this
case, the override switch MUST be turned 'off' for the step to retract.
6. Turn the vehicle ignition off and open the door. The step will extend and lock in the 'down' position.
This is the 'Auto Extend' feature. When the vehicle ignition is turned on, the step will activate with the
door movement, regardless of the step override switch position.
NOTE: If the yellow wire from the 4-way connector is not connected to an ignition power source, the
ignition will not cause the step to retract if the step override switch is on, regardless of the door
position.
If the ground to the control unit is lost, either between the step control unit and the vehicle chassis (the long green
ground wire) or between the vehicle battery and the ground (negative battery cable) the step will not function.
Make sure the battery terminals and all wire connections are clean and tight. Verify that all wires meet the minimum
requirements.
Operation
If the vehicle is driven with the step in the extended position, there is the possibility of causing
major damage to both the step and the coach.
Step control wiring is only to be used for step and step light (provided with the step) functions. Do
not splice, cut or tap into any of the step wiring. Failure to heed this warning may result in voiding of
the warranty, and/or failure of the step control, which may result in the loss of step function or re
in the step control.
