DESCRIPTION SOLUTION HOW TO CHECK
1 - 6 Solenoid High
Resistance
Voltage across
solenoid (battery
side (logic power)
to controller side
measured (B+
terminal)) is greater
than the hard coded
5V.
• Replace solenoid • Test the solenoid by measuring ohms
across the large terminals.
• The error usually only occurs when
drawing large currents (200A)
through the solenoid. The solenoid
may be under rated or oxidizing
with ag
1 - 7 Flash Memory
Error
Code updates from
the App may force

move during brake
check.
• Check motor brake • Turn key off and disconnect brake
harness from motor brake. Try
pushing vehicle, you should not be

• If new brake has been installed,
check installation, over/under
torquing brake can cause issues
1- 10 Resistor
Missing
The large external
power resistor was
not detected during
start up tests.
• Check resistor wiring • Resistor wires should go to switched
side of solenoid and to the ‘R’
terminal on the controller
2 - 1 Direction
Switch Fault
Both FWD & REV
signal came on at
the same time.
• Check and replace
FWD & REV switch
• The diagnostic page of the App will
give you readings for the Forward
switch and Reverse switch
• Check the Switch. Does the Switch
feel the same when toggled from
FWD to Neutral to REV? If so check
continuity of the switch.
