inputs applied in incorrect sequence.
2. Faulty wiring, crimps, or switches at KSI,
interlock, direction, or throttle inputs.
3. See Monitor menu » Inputs.
4. Emergency Reverse operation has
concluded, but the throttle, forward and
reverse inputs, and interlock have not
been returned to neutral.
1. This is a safety fault caused by a change
in certain parameter settings so that the
vehicle will not operate until KSI is cycled.
For example, if a user changes the Throttle
Type this fault will appear and require
cycling KSI before the vehicle can operate.

SET / CLEAR CONDITIONS
Set: HPD (High Pedal Disable) or sequencing fault
caused by incorrect sequence of KSI, interlock,
direction, and throttle inputs.
Clear: Reapply inputs in correct sequence.
Set: At the conclusion of Emergency Reverse, the
fault was set because various inputs were not
returned to neutral.
Clear: If EMR_Interlock = On, clear the interlock,
throttle, and direction inputs. If EMR_Interlock = Off,
clear the throttle and direction inputs.
Set: Adjustment of a parameter setting that requires
cycling of KSI.
Clear: Cycle KSI.
Set: 1) Failure to receive heartbeat from 3140 Gage
on startup, or 2) Not receiving PDO messages in
adequate time period.
Clear: Restore CAN communication and cycle
keyswitch
Set: Tow Switch (SW-4, Pin 10) closes or Tow Switc
wiring shorts to active high signal while vehicle is not
in Tow Mode and is moving.
Clear: Cycle Keyswitch
Set: EM Brake Type set to 1.
Clear: Set EM Brake to 2 and cycle keyswitch
Set: Throttle is above "HPD Threshold" and any of
the following is also occurring: 1) Vehicle has been
turned On for less than 100 ms. 2) Operator is off
seat for more time than the 'Interlock Open Delay'.
3) Vehicle is stationary and the keyswitch is in
Neutral.
Clear: Reduce throttle below the parameter "HPD
Threshold"
Set: Throttle is actuated in "gear" before controller
"sees" Neutral (after key "on").
Clear: Return Keyswitch to Neutral
