The following Step Test Procedures have been provided to troubleshoot and test all of the Kwikee® Automatic
Electric Step functions. They are designed to initially check the step's basic functions separately from the RV wiring
to determine whether or not the step is malfunctioning. The following procedures test the various components of
the step until the source of the malfunction is located. Using these procedures will shorten and reduce the time
spent troubleshooting.
Some portions of the test procedures require additional equipment. This equipment includes: a voltmeter, a well
charged 12 volts DC automotive battery, and a 4-way connector/pigtail Part Number 909306000 (Kwikee®) or Part
Number 369243 (LCI®).
If you need assistance, contact Lippert Components, Inc. Customer Service at 1-574-537-8900.
Step Test Procedure
1. Inspect the step for visible damage that might restrict the step operation.
2. Obtain a 4-way pigtail connector Part Number 909306000 (Kwikee®) or Part Number 369243 (LCI®).
Troubleshooting
12 volt automotive batteries contain sulfuric acid which can cause severe burns. Avoid contact with
the skin, eyes and clothing. 12 volt automotive batteries produce hydrogen gas which is explosive;
keep cigarettes, open ames and sparks away from the battery at all times.
Keep ngers, arms, and legs clear of step mechanism while performing these tests. Do not allow the
battery terminals to come in contact with the step.
