5 F25001*
5 F25002 2 An issue has occurred with the PST
unit. Check PST Unit
6 F26001 2 Throttle value is greater than 20%
at power up. Release throttle
6 F26002 2 Wire-off detected in electrobrake
circuit. Check electrobrake wiring,
ensuring current flows
when energized.
6 F26003 2 Direction is changed and vehicle
speed is greater than allowed. Select neutral switch to
clear the fault.
7 F27001 2 Measured ORFET voltage differs
too much from measured output
voltage. Check vehicle wiring.
7 F27002 2 Controller has entered thermal or
voltage cutback region. Check for temperature or
voltage cutback condition
and take appropriate action.
8 F28001 2 Thermal or voltage cutback factors
have reduced below user-defined
levels. Check for temperature or
voltage cutback condition
and take appropriate action.
10 F20101 2 One or more configured RPDOs
not received within 3s at start up
or 500ms during normal opera-
tion. Check status of all nodes
on CANbus. Check PDOs
on all CANbus nodes
12 F22101* 2
12 F22102* 2
12 F22103 2 Vehicle application subsystem is
not receiving control or status
information. Check CANbus wiring and
configuration of J1939
signal mapping.
12 F22104 2 Controller failed to receive re-
quired CAN messages. Check CANbus wiring and
CAN network.
12 F22105 2 A message has been lost in the
CAN protocol. Check CANbuswiring.
12 F22106 2 A message has been lost in the
CAN protocol. Check CANbuswiring.
12 F22107 2 A signal in a message has been
invalid for 5 cycles. Check CANbuswiring.
12 F22108 2 A signal in a message has been
invalid for 5 cycles. Check CANbuswiring.
14 F24101 2 EMCY message received from
non-Sevcon node and anonymous
EMC level. Check status of non-
Sevcon nodes on CANbus.
14 F24102 2 Boost enable state from hardware
and processor comms does not
match. Check DCDC unit.
14 F24103 2 Boost stage is above maximum
operating voltage.
