ASA Electronics iN-Command JRVCS105 Troubleshooting Manual page 11

Symptom
Display Commander (DC) will not
turn ON or no front panel operation
No power to the Body Control
Module (BCM), The Red Light is
off
DC screen flashing on and off after
installation
DC not controlling light or motor
functions, and DC is showing
0VDC
Electric motors do not move
Travel Lock is on
*Relay not activating
Troubleshooting The iN-Command system is pretty painless. The BCM and DC simulate all the lights, gauges,
and switches on the old control panels. The BCM Pin Vales 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
tanks correctly. Also, if the BCM has the correct output voltage or signal , 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 program is needed.

Troubleshooting
Solution
Try cycling the DC with the Power button.
Check main fuse in Distribution Panel.
Press Reset button on BCM.
Check for 12V+ on +12VDC wire to DC using a
Digital Multi-meter.
Check ground wire connection to DC.
Try cycling power using the RV main breaker.
Check if the Red power LED is off,
Check the fuse in the Distribution Panel.
Check 12V+ on wire at pin 35.
Disconnect wire from pin 7, if BCM powers up,
there is a short on the wire. Correct wiring.
Check Ground wire at pin 33.
Disconnect and reconnect 12V+ and Ground
wires from the back of DC.
Cycle power to the BCM and DC.
Check wire connections to DC.
Ensure Battery is charged. Plug in shore power.
Swap the TX and RX wires either at the BCM or
back of the DC.
Check for 12V+ at Pin 34. Ensure the relay
activates*.
Ensure 12V+ is removed from pin 19. Press
Reset button
Replace the relay with one from an unused
circuit by gently pulling it off the board. Relay is
an automotive standard at 12VDC coil,
40/30Amp 14VDC contact
