Troubleshooting
DC/SP will not turn on
Verify the BCM is powered on.
Check main fuse in Distribution Panel.
Verify red wire from BCM 12V (pin 37) is connected to 12V input on DC/SP.
Verify ground from BCM (pin 40) is connected to ground input on DC/SP
No Power to the BCM
Check if the RED power LED is on.
Check the main fuse in the Distribution Panel.
Check for 12V at pin 36.
Check for ground at pin 34.
Cycle power to the BCM
DC/SP Flashing On and Off
Ensure wires from BCM to DC are not damaged or pinched
Ensure wires are making contact with pins.
Press Reset button on BCM.
Cycle power to the BCM.
Light Group is not working Check 12V at pin 16 and ground at pin 17.
Check Light Group fuse in the Distribution Panel.
Motor Functions are not working Check 12V at pin 35.
Travel Lock is on (Motor Functions Disabled) Ensure 12V is removed from pin 15 (When the brakes are no longer being applied, or tow cable
is removed).
Press Reset button on BCM.
Functions not operating from DC/SP or App and
Battery voltage displays 0V Check to Ensure RX and TX wires are connected properly (RX from BCM connects to TX on
DC/SP; TX from BCM connects to RX on DC/SP).
The NCS50 BCM with the SP/DC allows you to either use the RV Switch Panel or iN-Command App to control your RV’s functions. The BCM Pin
Values portion of this guide will clear most issues. Basically, if the BCM does not have the desired voltage, or signal input, it will not be able to
function or read battery voltage. Also, if the BCM has the correct output voltage, but nothing is functioning, the problem lies in the wiring leading to
the malfunctioning component or the component itself.
Any issues that are related to iN-Command that cannot be cleared using the above list will be tied to the BCM and DC hardware and software.
Careful inspection of the BCM will need to be done (possibly blowing the BCM board with air to remove any dust, debris, or conductive material). If
the BCM looks clean and undamaged (without burnt or cracked components) with all the wires secure and not touching each other, troubleshooting
the software is needed.
Contact an ASA representative 1-877-845-8750 for questions regarding iN-Command software or hardware issues.
