Product Information Steps with Control Unit NOTE: An important change covered in this owner’s manual is the “Step Lockout Switch” (previously called the “Power Switch”). The name changed because of a change of functionality from the former “Power Switch”. The new control units are equipped with an ignition override system designed to prevent the vehicle from being driven with the step in the extended position (STEP LOCKOUT SWITCH IS IN THE ‘OFF’...

If the step does not work or operates erratically (for example, extends part way and shuts off): Check the vehicle battery. Low supply voltage may cause erratic operation of the step. Poor ground connections may also cause erratic operation of the step. Check battery voltage and condition.
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. Always make sure that the step is fully retracted before traveling. If the step is left extended and strikes an obstruction while the vehicle is moving, major damage to both the step and the vehicle could result.

Connect the motor’s red wire to the positive battery terminal and touch the motor’s yellow wire to the negative battery terminal to extend the step. To retract the step, reverse the connections. NOTE: On steps with reverse polarity plug Lippert® Part Number 365884 reverse the red and yellow wire connections to perform this test.

To check the door switch: Connect a voltmeter between the red wire from the 4-way connector (vehicle half) and the brown in the same connector (Fig. 9). The voltage should be a minimum of 12 volts DC when the door is closed and zero volts when the door is open.

Maintenance Step Assembly Lubrication Clean all mud, salt, and road grime from the step before lubricating. Lubricate all moving parts (bearings, pivot points, slides, clevis pin, and drive linkage ball) every 30 days with a good quality moisture and heat resistant penetrating grease.
Maintenance In a Salt Environment To maintain step finish when the step is exposed to a salt environment for extended periods of time, routinely spray step with fresh water. Adjusting Cam Stops If the cam stops are not properly adjusted the step may not extend fully to the locked-out position. Using a step with loose or out-of-adjustment cam stops may cause damage to the motor assembly and/or the drive linkage.
