(RV-C) Communication issues
Make sure the CAN-Low does not have a short to +12V.
Make sure the CAN-High does not have a short to ground.
Make sure there is not a short between CAN-Low and CAN-High.
Check RV-C plugs and pins to make sure there is not a loose
connection. Try and power cycle all the components.
Make sure the RV-C connector is pinned correctly.
Try a different RV-C cable.
Press the reset button on the BCM.
No BCM Power
Check if the Red Power indicator is lit.
Press the Reset button on the BCM.
Verify 12V on Pin 42 and Ground on pin 39.
Check Fuse in Main Breaker Box.
Cycle RV Power at the Main Breaker Box.
No DC Power
Cycle power with the Power Button. (Press and hold the
power button for 5 seconds.)
Verify 12V and Ground at the back of the DC.
Verify no blown fuses in the Main Breaker Box.
Electric Motors do not move
Verify 12V on pin 40.
If the Battery Disconnect switch is off, turn it on. (Some
models pull the slide power through the battery disconnect.)
Aux. Motors do not move
Verify the AUX motor Control Relay Kit’s pigtail harness is
connected and seated properly on the BCM.
Make sure the Motor Ground (black) and Motor +12V (red)
wires are connected and getting power.
Check fuse in Main Breaker Box.
Water Tank
Make sure the common pin (Pin 8) is outp7VDC. If no
voltage, disconnect the tank harness and test the pin on the BCM. If
there is voltage now, that indicates the common wire has a short to
ground.
If one of the tanks is reading, but another tank does not read,
remove the wires from the bell caps and swap the tank wires. If the
opposite tank now reads, that indicates the BCM is fine and there is
an issue in the tank line.
The tank level voltages are as follows:
o
1/3: .75 to 1.74
o
2/3: 1.75 to 3.59
o
3/3: 3.6
