Certification Checklist Diagnostic Procedures
The following operations and conditions must be functionally verified in order for the lift to be FMVSS 403/404 compliant. If an operation does not function as described or a condition is not met, follow the refer- enced procedures to correct the problem or contact a Braun Corporation Product Support representative at
•Vehicle movement is prevented unless lift door is closed, ensuring the lift is stowed.
1.Verify lift stowed signal - pin 7 on the pump module has a +12 volt signal OR pin 9 has a ground signal (depends on interlock used).
2.Refer to the interlock installation instructions.
•Lift operation shall be prevented unless the vehicle is stopped and vehicle movement is prevented.
1.Verify vehicle secure signal (pin 6) has a +12 volt signal.
2.Refer to the interlock installation instructions.
•The platform will not fold/stow if occupied.
-Refer to Platform Fold Pressure Adjustment procedures.
•The inner roll stop will not raise if occupied.
-Call Product Support
•The outer barrier will not raise if occupied.
-Refer to Outer Barrier Fold Pressure Adjustment
•Verify platform lighting when lift is deployed and pendant illumination when lift is powered.
1.Replace bulb(s) in the light housing.
2.Check fuse (5 amp fuse on circuit board; F13)
•A visual and audible warning will activate if the threshold area is occupied when the platform is a least one inch below floor level.
1.Remove the threshold warning plate
2.Verify the threshold strip switch connectors are connected (see illustration on Page 3)
3.Replace the threshold strip switch
4.Reinstall the threshold warning plate
•Platform movement is prohibited beyond the position where the inner roll stop is fully deployed (up).
-Call Product Support.
•Lift platform movement shall be interrupted unless the outer barrier is deployed (up).
-Call Product Support.
